Greenhouse Perpetual Grow In The Tropics

[CBDMed]

It's not really a test. It's more like just seeing how big they'll get in veg, and to allow phenotypic differences to fully emerge.

Ahh, right! Because you are a clones guy.
That would make sense.

They are so tall I need to top them in order to fit in the flower house... space in there is only about 8 ft. I actually just got in from topping them! (pics later)

So that's part of it, but not the whole story. Also, I just have a laid-back Hawaiian approach and don't carefully plan out the whole sequence from clones, to veg, to flower. It just flows organically. If the flower house is full, then I have to wait. I also need to stagger the harvests so that I don't have too much bud material to process.

Next time around I'll be growing the clones and topping much sooner, to make them more bushy.


This one I have is actually a Gelato cross from Humboldt, Calif., not a pure Gelato.


First time with these Gelato cross and Blue Dream cross (also very tall). The 2 Blue Dream I'm guessing will start showing flowers next week, then it will take probably another 5-7 weeks for buds.

Sounds great!

Some pics from yesterday. (Sorry about low-quality phone camera... getting a much better one very soon.)

In the veg house... L to R, meet Lorraine, Gilda, and Jane... the Gelato cross plants, after being topped. They got plenty of water w/ fert yesterday, but are showing a bit of droop today, so I'm feeling they have really maxed out their pots... too long in veg. I will nurse them along, but this super-vigorous variety really needs to complete its lifecycle on schedule. I can maybe fit one of them in the flower house... we'll see.

The potential 20:1 CBD seedling is doing very well. I'm looking forward to having the buds tested.

18 clones going now... 9 new ones as of yesterday, from the Gelato cuttings

In the flower house, foreground are the 2 Blue Dream cross plants... they are leggy and not a lot of foliage... next time around with the clones, it will be good to top early to make them more bushy. They are almost showing the start of flowering.

Well into flowering now... one of the 2 GSC x Kush plants... a favorite in my grow. Clones of clones.

 

[cbdhemp808]

Lorraine, Gilda, and Jane. I felt it was a good idea to defoliate a bit on them today... mostly giant old fan leaves that were obstructing other leaves, and some off-looking leaves. I've figured out a way to rearrange in the flower house, and will move Jane in there next dry cycle. I think Gilda's going to become the mom of choice. As for Lorraine, I'm thinking of flowering her on the part of the flower house deck that is uncovered, no roof. That would be an interesting experiment.

 

[cbdhemp808]

In the flower house today...

Full up... 6 plants, 4 varieties... (2) GSC x Kush, (1) Maui Wowie, (2) Blue Dream x, (1) Gelato x. First to finish will be GSC x Kush, then Maui Wowie, then the Blue Dreams, then Jane the Gelato.

Side view. One of the GSC x Kush on the far right foreground, starting to smell good!

Jane the Gelato happy in her new home

Everyone is looking happy! Especially Chunky Boy, haha

Everyone is looking happy! Especially Chunky Boy, haha

cuz he's got the life of Riley, our mini black panther. BTW Chunky is just one of his nicknames... his real name is Akuma (short for the Japanese, yoru no akuma, or night demon). he's a very good boy. we also have his mom who is part Tonkinese... extremely friendly and with the lengendary Tonkinese "kissing" habit. look it up!

 

[CBDMed]

I used to have some Siamese, and they were great fun.
Very interesting about the kissing cats!

Hey, sorry if I missed this, but may I please ask, what size are your greenhouses, and how many girls does each one hold?

 

[cbdhemp808]

Hey, sorry if I missed this, but may I please ask, what size are your greenhouses, and how many girls does each one hold?

The veg house is about 12 x 16. However, there's a lot of other stuff in there... 2 tables, a low bench, a work bench, and a bunch of empty pots, etc. Someday I will get things more organized. The available space for plants would fit about 8 large plants. I need to leave plenty of space between plants for air flow, due to our mold-prone environment. I also don't have fans rigged up in there. Being off-grid, I need to be careful with power use.

The flower house is about 13 x 10.5. There's a lot less clutter in there. 6 large plants will fit.

Hey everyone, here's my veg greenhouse, photo taken today.

@gwhunran @Tkmk @The70’s @TwelveCoffee @Buds Buddy @HappyHazmat88 @Vegan4life @stardawg17 @Gandalfthewhite @Foss @Ganja Droid 420 @PREZEE @Phytoplankton @Diyandimitrov @Trala @HappyDays @NuggetJuggler @Phillybonker @kisshell @Farmer Reading @Grand Daddy Black @Tokin Roll @DeeBoy @Kanno26 @Jon @Brewsterman @Cola Monster @Sloppy @Bill284 @Braddah Waiheesohai

Veg/clone greenhouse w/ photoperiod lighting, 13w daylight spectrum LEDs.

The bigger plants are in 15 gal. smart pots. Custom living soil mixture including coco, perlite, homegrown worm compost, and all vegan organic nutrients. I use Mycos root booster "in the hole" when I up pot.

The Blue Dream and Gelato genetics are the most impressive plants I've ever grown – huge leaves and fast growing. The growth pattern makes me feel like they want to be big trees! I'm looking forward to how these turn out, and to take clones and grow the clones, which I'm guessing will have more dense branching than the seedlings. Genetics from Northern Cali. Interesting to see the Blue Dream cross next to Gelato cross – similar growth habit and leaves, but the Gelato is a lighter shade of green (same soil and conditions).

First time I've grown a 100% indica plant – Godzilla.

Hey CBD,
Thanks for posting your thread online. I am learning a lot.
I think our climate is slightly different, but after that there seem to be more similarities than differences.
I was wondering if you might have any opinions that you might like to share about 15G smart pots?

The reason I ask is that I am hoping the visa situation will (finally!) be cleared up soon, and we want to get land, and then build a greenhouse or six (hahaha).
(I am hoping to transition to regular seed, so I want some smaller greenhouses on the side, for males.)

There is a greenhouse here that plants direct in ground, I think either in March or April.
Then they run lights 24/7 until fall, when they cut the lights (I think about the same time as the Fall Equinox.
(I think Gas Lantern Routine would do better, but that is another matter.)
Only, if I start in Solo cups at the Spring Equinox, and then uppot, I could Gas Lantern them until the Fall Equinox, 6 months later.
So would that be 6 months of vegging?
Then I could close out the summer grow, and grow autos (for variety) during the winter. (I see some of the sponsors have some real good CBD auto regular varieties that take 3-4 months, which is perfect...)

So my question is, I see you also run mostly indica-dominant.
And you said you use 15G smart pots.
Do you find 15G smart pots big enough for vegging 6 or 7 months?
Or do you ever wish you had 20s?

Also, have you ever considered planting straight in the ground for a final container?
Or all things considered, is it just easier (or better) to use smart pots?
Thanks.

We think we might want off-grid (at least for a backup).
I used a generator-inverter setup one time when I lived off grid in northern California, and I bought a solar generator one time, but I have never done a full-fledged off-grid thingy, and wondered if you would mind sharing advice, etc.
Thanks.

Moved 3 plants to the flower house – the 2 GSC x Kush and the little Maui Wowie clone mom – creating much needed space in the veg house. Moved the veg plants around for better spacing, and up potted a couple small seedlings. All plants looking fantastic. The Gelato-x and Blue Dream-x have shot up, and I elevated some of the lighting. All plants got a solid watering, w/ high-N fert in the water.

In other news, there's one more CBD plant almost finished in the flower house. This one produced a very nice yield for a smallish plant, and my careful pruning paid off. Here's some pics...

it's a 2-stem plant, and each stem ends with a "big" cola ... here's one of them

That looks beautiful here's some of mine right now. I haven't went to my outdoor spot in a while someone else is taking care of it I bet you they're doing real good too.

 

[cbdhemp808]

I think you're feeding them too much gold... must be very expensive. haha... cool lighting on that shot!

 

[Jame9111]

I think you're feeding them too much gold... must be very expensive. haha... cool lighting on that shot!

Yeah I joined this site not long ago to try to fix them we came to that conclusion..

 

[cbdhemp808]

I was wondering if you might have any opinions that you might like to share about 15G smart pots?

We make our own smart pots out of black weed cloth that we purchase by the role online, which is permeable to water and air. I have designs for multiple sizes, but we chose 15 gal because it was a comfortable max. size for 2 people to lift into the wheelbarrow when moving from veg to flower house. As of today, I'm starting to think that 10 gal may be sufficient. But I'm not going to change just yet... I need to do some experiments with moving plants to flower sooner.

There is a greenhouse here that plants direct in ground, I think either in March or April.
Then they run lights 24/7 until fall, when they cut the lights (I think about the same time as the Fall Equinox.
(I think Gas Lantern Routine would do better, but that is another matter.)

That's an interesting concept... growing in a greenhouse but using photosynthetic lighting. Are they trying to maximize light, or control flowering? If the latter, then yes, night interruption would be much better.

Only, if I start in Solo cups at the Spring Equinox, and then uppot, I could Gas Lantern them until the Fall Equinox, 6 months later.
So would that be 6 months of vegging?

The dreaded "S" word (ha ha)... I use 2" square nursery pots and allow plants to grow for about 5 days (~3" tall), then up pot to 1 gal, burying the stem so about 1.5" is showing above the soil.

It's a good question... how long to keep plants in veg. 6 months is definitely doable. The question is, what's the best duration of veg for a given strain, in terms of best outcome for flower production. Pot size is also a key factor.

So my question is, I see you also run mostly indica-dominant.
And you said you use 15G smart pots.
Do you find 15G smart pots big enough for vegging 6 or 7 months?
Or do you ever wish you had 20s?

Yes, I do favor indica dominant plants. I tend to like vaping indica over sativa. I also like blending buds, when grinding, to produce mixtures of THC and CBD, and sativa does have a nice energizing effect when combined with CBD. This is what I'm referring to when I say THC "turns up the volume" on the CBD.

Regarding pot size as relates to duration of vegging... that's a good question. I think of it this way... a given photo strain will have its optimum lifecycle duration – i.e. optimum time in veg as well as in flower. Pot size needs to support the plant through this, and if you have insufficient pot size, then the outcome will be the pot will be "maxed out" too soon – i.e. too much root growth for the pot and insufficient nutrients, resulting at least in a small plant, and at worst, in various other problems.

As you can imagine, there are various factors affecting all this.

Let's look at a best-case, hypothetical scenario first. Let's say the plant is a slow-growing indica. It will be a short plant when it reaches its max height, and it will do just fine in a 6 gal black plastic nursery pot. Let's say vegging time is 2 months, and flowering time is also 2 months. The plant is grown in a well-fertilized, balanced organic living soil. The plant is also fed during watering, every other watering, with a high-N liquid fert w/ other nutrients. During flowering, the weather is mild, not hot. The plant should grow very well and produce a nice yield.

Now for a hypothetical worst-case... Let's say the plant is a tall-growing hybrid variety (50/50 indica/sativa). This plant will easily reach 8 ft tall or more, but height depends on the container size and other factors. The plant is grown in an 10 gal black plastic nursery pot. Let's say vegging time is 4 months, and flower time 2 months. The plant is grown in a well-fertilized commercial soil mixture, but without emphasis on soil biology. No supplemental nutrients are added during watering. By the middle of flowering, the weather is hot, and this plant has maxed out its pot – the pot is root bound and needs to be watered almost every day. Soil nutrients have been depleted, and all the watering is leaching out minerals from the soil. The soil becomes too acidic. The plant starts to show signs of serious nutrient deficiency – leaves start to yellow and die. Drooping leaves encourage the grower to water more, but this only makes things worse. The grower consults the gang at the 420 magazine forum, and thankfully, is just barely able to pull off a harvest.

Also, have you ever considered planting straight in the ground for a final container?
Or all things considered, is it just easier (or better) to use smart pots?

Because I have the two greenhouses, and need to control flowering, I need the portability. I am considering growing some trees in our big greenhouse, once I do the repair/renovation work. In that case, I will use our 40 gal smart pots, and will probably grow clones of both the Gelato and Blue Dream genetics that I'm growing now. Those plants will be able to grow very tall, and top out around 9.5 ft (to fit the space). I haven't decided yet if I'll use night interruption lighting for that grow – it would be interesting not to use it, and let the plants just flower as soon as they're ready.

 

[cbdhemp808]

Also, could I please ask you about your off-grid setup?
We think we might want off-grid (at least for a backup).
I used a generator-inverter setup one time when I lived off grid in northern California, and I bought a solar generator one time, but I have never done a full-fledged off-grid thingy, and wondered if you would mind sharing advice, etc.

We have no services at all on our rural road, so we are off-grid by necessity. This means water catchment, solar electric, and satellite internet. We haven't even used a generator, but I just bought a small one for a project that requires it.

I have an extension cord running out to the big greenhouse (presently offline), and on to the veg house, in conduit.

Our solar power system is very small... about 40amps @ 12v. We have 6 x 6v deep cycle golf cart batteries, wired for 12v. That feeds a 1500w pure sine wave inverter. The system runs our refrigeration, LED lights, blender, satellite internet, power tool charging, and an efficient washing machine.

My night interruption lighting in the veg house consists of about 8x 13w daylight spectrum bulbs, which are on a timer to go on for a few minutes at 12 midnight, 2am, and 4am. The 2 clone domes each have a 24w SANSI grow light which is on from about 6:30am to 7:00pm.

We make our own smart pots out of black weed cloth that we purchase by the role online, which is permeable to water and air.

That's a great idea!
I don't have time for that at the moment, but I need to get the fabric pots on order, because shipping can take a while unless you want to pay zillions.

I have designs for multiple sizes, but we chose 15 gal because it was a comfortable max. size for 2 people to lift into the wheelbarrow when moving from veg to flower house. As of today, I'm starting to think that 10 gal may be sufficient. But I'm not going to change just yet... I need to do some experiments with moving plants to flower sooner.

Ahh, ok. Perfect.
I ordered the 15Gs.
I was thinking 15s, but was wondering if I should go 20.
But if you are thinking of dropping to 10, I will start with 15s (when we get there, haha).

That's an interesting concept... growing in a greenhouse but using photosynthetic lighting. Are they trying to maximize light, or control flowering? If the latter, then yes, night interruption would be much better.

Yeah, I am not really sure what they are doing.
But it did not sound real healthy to run lights 24/7 without a rest, so I kind of lost interest in going to see their operation.
I might want to see it, if I want to plant in ground. But I think mostly I will be in a greenhouse, in containers, because it is so much easier to control the moisture, at least for a small operation.
I heard that they had some under greenhouses, and some that just grows wild, out in the open (fenced, but open air).
But if they don't let the plants rest, then I am not so interested to go there.

The dreaded "S" word (ha ha)... I use 2" square nursery pots and allow plants to grow for about 5 days (~3" tall), then up pot to 1 gal, burying the stem so about 1.5" is showing above the soil.

Ahh, ok. I only got started on them because I am trying to imitate Emilya's watering techniques as best I can.
She uses Solo cups, so I broke down and got some.
I plan to wear them completely all the way out, if that helps. I hope to use them for many years to come. It seems like less plastic than to buy hard pots of the same size.
I looked online and I can get hard pots of the same size that should last a lifetime, but it will be like $160 to get them here. So it seems like there is actually less "carbon footprint" (to use a term) with the Solo cups than if I buy hard plastic pots. I do try to treat them gingerly, so they will last.

It's a good question... how long to keep plants in veg. 6 months is definitely doable. The question is, what's the best duration of veg for a given strain, in terms of best outcome for flower production. Pot size is also a key factor.

Those sound like good questions.
I did grow Northern Light one time, and that was a small, compact little plant!
I never did an autopsy on the root ball on that one, to see if it could have lived in a smaller pot. Next time I grow Northern Light I will have to do an autopsy on the rootball.
Anyway, I think I get what you are saying.
I thought if I did sativa I would probably want a really big pot, depending on the rootball, but I don't know how well sativa does in a greenhouse. How tall did you say your greenhouse was?

Yes, I do favor indica dominant plants. I tend to like vaping indica over sativa.

Sí.
I do like sativa sometimes, but somehow indicas seem a lot more potent.

I also like blending buds, when grinding, to produce mixtures of THC and CBD, and sativa does have a nice energizing effect when combined with CBD. This is what I'm referring to when I say THC "turns up the volume" on the CBD.

Sí!
I can't wait to get back to growing photoperiods! If I remember correctly, Harlequin is an all-CBD sativa that is my all-time favorite strain (and Harle-Sour Tsunami is good also).
I don't know if everyone receives it the same way, but to me, Harlequin is a very clear-headed CBD strain. Probably my best strain for clear-headed, on-your-feet kind of work.

Regarding pot size as relates to duration of vegging... that's a good question. I think of it this way... a given photo strain will have its optimum lifecycle duration – i.e. optimum time in veg as well as in flower.

Sorry, I was with you in agreement right up until that last part, and then you lost me.
What it means, "without emphasis on soil biology"?

No supplemental nutrients are added during watering.

I really liked the idea of Subcool supersoil, because it makes watering a snap!
I *just harvested the last of the non-Subcool plants, but I must confess that I got in the habit of feeding then the existing liquid 'nutes, because I am still trying to build a stash. (Still running behind.)
I am thinking that the extra nutes will help the little girls grow faster.
That could be completely wrong, but I am trying to them get going.
Once I get to my final destination, I hope it will be much more of a set-and-forget or else a Jadam or KNF situation.
Does any of that relate or pertain?
Or did I miss it entirely, haha?

By the middle of flowering, the weather is hot, and this plant has maxed out its pot – the pot is root bound and needs to be watered almost every day. Soil nutrients have been depleted, and all the watering is leaching out minerals from the soil. The soil becomes too acidic.

Ahhh.... sí....

Because I have the two greenhouses, and need to control flowering, I need the portability.

Ahhh, ok! That makes sense!
And you go that way because all you need to do is cut the night lights?
So you transport the 15 from the night-light-veg house to the non-night-light flowering house?
And that way, you have a constant harvest???
Wow, fresh weed is always the nicest! I love vaping all of the early aromas and flavors off of fresh buds! It makes for a longer session, but for me it is so much nicer!

How could I do it with regular auto CBD seeds?
Sometimes you buy 5 seeds, and sometimes 10 or even 12.
I guess with 5, they are assuming that at least 1 or 2 or even 3 will be a female, and you can select for the strongest male.
However, they all go into flower around a certain age.
So maybe start the 12 seeds, say 6 are females, and keep the strongest male, that is a crop of 7? And then separate the male to a male flowering house?

Or would you want separate small rooms for each male that flowers, so you can be sure to isolate the pollens, without them mixing?
And put up bee screens on both the male and female houses?

It kind of seems like with auto regular CBD plants, I will need to end up running "batches" in gender-segregated housing???

I am considering growing some trees in our big greenhouse, once I do the repair/renovation work.

Great!
What is your ceiling height on that one?
And what needs to be renovated/repaired?

In that case, I will use our 40 gal smart pots, and will probably grow clones of both the Gelato and Blue Dream genetics that I'm growing now.

Oh, wow. 40 gallons....

Those plants will be able to grow very tall, and top out around 9.5 ft (to fit the space). I haven't decided yet if I'll use night interruption lighting for that grow – it would be interesting not to use it, and let the plants just flower as soon as they're ready.

Ahhh.... yeah, now I see what you are saying.
Yes, kind of, if you were hypothetically to start them in the spring, how big would they get by fall?
And then that is kind of their "ideal expected growth characteristic" in a normal plush growing season?
And based on that, you could tell what size pot you need?
Makes sense.

(Hmmm.... now I wonder if I should get some 40 gallon pots, too!)

Yeah, ok. I can relate. That seems like my setup when I was in northern California, except that I could not do solar, because I was way down in a draw.
I had a propane fridge and propane stove. I would run a generator whenever I wanted to run the vacuum cleaner, or power tools. I tried to charge it once a day, and I would usually use the computer at the same time. And I had 6 deep cycle batteries, and an inverter. So I get what you are talking about. So basically I would just add solar panels to that.

I used to love being way out in the middle of nowhere, with no traffic, and no interruptions. It was incredibly peaceful. It was like camping every day.

 

[cbdhemp808]

That's a great idea!

oh man... I wrote a long detailed response and then my computer shut off for no reason... lost the whole thing!

will attempt again later.

Some pics from today. I now have a badass new quad-camera in my new phone, so I'm looking forward to taking some awesome macro shots... once I figure out how to use it! I've got a tripod mount on order. Enjoy!

I looked online and I can get hard pots of the same size that should last a lifetime, but it will be like $160 to get them here.

This is what I use, 2" square nursery pots. You can get 100 online for about $20. Shipping shouldn't cost very much.

I thought if I did sativa I would probably want a really big pot, depending on the rootball, but I don't know how well sativa does in a greenhouse. How tall did you say your greenhouse was?

I think they'll do just fine. They can be topped early to produce a more bushy plant. I have been growing Maui Wowie, which is maybe 80% sativa, and haven't even needed to top. Some of my plants can get well over 8 ft in the veg house, but I need to top them so they fit in the flower house – i.e. pot plus plant must be less than 8 ft.

I can't wait to get back to growing photoperiods! If I remember correctly, Harlequin is an all-CBD sativa that is my all-time favorite strain (and Harle-Sour Tsunami is good also).

I would like to grow Harle-Tsu, but haven't found a good seed source yet. Do you know of one? Some Harle-Tsu phenos are supposed to reach 20% CBD. THC is supposed to be 1% or less.

Sorry, I was with you in agreement right up until that last part, and then you lost me.
What it means, "without emphasis on soil biology"?

That was part of my worst-case hypothetical grow scenario, meaning the grower wasn't thinking about soil micro-biome – i.e. adding things like... fresh worm compost, mycorrhiza, enzyme tea, aerated worm compost tea, biochar, etc.

RE: moving plants from veg house to flower house

And you go that way because all you need to do is cut the night lights?
So you transport the 15 from the night-light-veg house to the non-night-light flowering house?
And that way, you have a constant harvest???

Yes, the flower house is far enough away, and there's thick vegetation in between, so the light doesn't reach the flower house. I don't have a "constant" harvest... there's a lag between harvests. I can cut down the lag by staggering the addition of plants to the flower house. Currently I typically wait about 5-7 weeks for flowers to finish, harvest, and then move the next batch from veg to flower. The flower house can hold 6 big plants, so I could move 3 in, and then wait 2-3 weeks, then add 3 more. Or better yet, just add 2 at a time, and wait 2-3 weeks before adding the next. Once this pattern is started, then all I need to do is add 2 plants each time I harvest 2 plants. For this to work smoothly, the varieties should all have similar flowering times.

RE: how to do a perpetual grow using regular auto seeds

How could I do it with regular auto CBD seeds?
Sometimes you buy 5 seeds, and sometimes 10 or even 12.

And put up bee screens on both the male and female houses?

I'll answer your last question first... yes, it's possible bees would carry cannabis pollen, but it's very much beside the point, because cannabis pollen is easily carried far in the air currents. Cannabis is wind pollinated. So, what you need to do is not release any pollen into the surrounding air.

I haven't done any breeding to produce seeds yet, but I have collected pollen before. I used tiny amber glass vials with screw-on lids (about 1 in. tall) to contain the collected pollen, and then put these in the freezer where the pollen remains viable for at least 18 months.

The way I would approach this would be to select the tallest, best male plant, and then a few days before the plant releases pollen, move it into an indoor isolation chamber – for example a grow tent. You only need a low-wattage, full-spectrum LED bulb in there. The trick is not to release any pollen into the surrounding air, when you are collecting pollen. The pollen is stored in the freezer until you're ready to hand-pollinate your females. (There's a lot more to this process, but this gives you an idea how it goes.)

RE: status of my big greenhouse

What is your ceiling height on that one?
And what needs to be renovated/repaired?

The height at the apex is about 10 ft. So, pot height plus plant height needs to be less than 10 ft.

It's a custom-built greenhouse with a custom design. It looks like a PVC hoop house sitting on top of sturdy side walls. The side walls have a 2ft base wall of painted masonite, and then 5ft of screen above that.

We are re-doing the roof frame and creating a ridge vent that will contain exhaust fans for cooling. There's also a bunch of weeds growing in there. It needs to be cleaned up, etc. With the ridge vent installed, we'll gain another 2ft of height on one side of the apex.

RE: selecting pot size based on "ideal" growing scenario

... if you were hypothetically to start them in the spring, how big would they get by fall?
And then that is kind of their "ideal expected growth characteristic" in a normal plush growing season?
And based on that, you could tell what size pot you need?

This is getting into the fringes of my understanding of the subject. I normally don't think much about what is the ideal vegging time – I just grow a bunch of strains and phenos, and then move plants from the veg house to the flower house organically, as space opens up in the flower house.

But I would like to evolve toward timing the move to better coincide with ideal timing, for any given strain, indica/sativa, etc. I don't even know of any particular information about benefits of vegging longer than necessary, or not. So, I have some experimenting to do. In terms of pot size, it's easy to see that vegging longer than necessary may imply a larger pot will be needed.
