MK-Ultra Hempy - C02 - 1000 Watts

Re: MK-Ultra Hempy, C02, 1000watts.

That's a very good point about keeping trash out of the tub and keeping the solution in the dark. Probably would get all kinds of algae and crap.

Fortunately, I think I could fix those shortcomings with some screen and a simple shade for the runoff. I hadn't even thought of those issues. Thanks doc!

I think your plan is sound.

If I was gonna go bigger, I'd go with a bato bucket system too. I'm surprised they're not more popular here in the US.

They're popular with some of the folks I know....and these guys grow on a much larger scale than anyone here on this forum.

What I like so much about the Bato's is that they're all interchangable. Just undo the top drip, pick up the bucket, move it anywhere, or plug another one in in its place. All you need is a PVC rail with a hole drilled in it for drainage.

Using the perlite medium saves on water. The system only needs to cycle on once or twice a day max....could go as little as every 3 days. Can't over water and the square footprint of everything makes good use of the lights. Having the plants up on tables makes pruning, spraying and LST quite easy as well.

How cool would it be to have 4 or 5 tables, each under a 1k light. Start a table, 12 days later start another...then another....pretty soon you're harvesting twice a month....perpetual.

The operation I saw had 3 Jack Herer mothers and 4 OG Kush mothers. He took 4 clones from each, every 12 days...vegged for 12 days and then flowered. 5 tables.

The perlite made for massive growth. No pests from soil. Hand watering is easy if there's a power outage.....and the plants can go a couple days without water unless it's really big.

I think you can tell I was impressed....

DocBud and Setting Sun. Great information. Just soak up as much information about Hempys Buckets as I can find. Now Researching Bato Bucket Systems. Exciting! Like I said everytime I stop in here DocBud I get Schooled.
Keep up all your doing, Great journal and great growin'. Thanks!

Damn I just started making/using hempy pots. Now DocBud mentions bato buckets. Wow, learning never ends. I like the hempy's hate the waste, now bato buckets recycle!!!! Just got to think out a way to do it on the cheap now.

The drain to waste aspect of hempy's is one of their best features. It's better to do that than the recirculate in a reservoir. If you measure out carefully how much you need to water, you'll get about the same in runoff that you would from evap. from a reservoir.

Also, remember that you're dumping that whole res every week or so.

Hempy's can't be beat for 10 or fewer plants.

For people with more free time, there is no reason you couldn't grow up to 20 plants this way. Hand watering would take a while, but it's not impossible if you've got the time.

I have aspirations for a larger scale grow, and I want to stick with hempy's.....hence the Bato buckets.

Day 26 of flower....nearly halfway there!

I've got two plants where the top colas are nearly filled in. Both should be in the 14 inch range. The plant that is furthest along is also the one that is starting to show a few yellowish fan leaves. The question is: Under feeding? Over feeding? Which one?

The last two feedings have been very light, designed to be flushes actually, and while the plant remains healthy overall, the yellowing margins have increased in the last 24 hours....so I'm going with under feeding.

Opinions are most welcome!

Re: MK-Ultra Hempy, C02, 1000watts.

The yellowing you get from underfeeding tends to look more generalized than that, and along with the tip burn, leads me to think it's overfeeding.

That particular plant may just be more sensitive than the others.

Thanks! What do you think I should do to correct the problem?
Does it look like Calcium, or just general nute burn?

The reason I flushed the plant was because I was feeding it aggressively and it's sister got a little bit of claw going....which is fixed now.

Hey Doc, your comment about the amount of run off when watering hempys leads me to believe I missed something. I was under the impression you water them 2 to 3 times a day to keep the roots that aren't in the res from getting too dry,can you clear this up for me?

When the plants are first put into the buckets, the roots aren't long enough to reach the bottom. Consequently, the first week to 10 days the plant looks a bit ragged, while the roots are growing hard to reach moisture. During this time, it is often a good idea to water 2-3 times a day, until the roots reach bottom. When that happens, there is no mistaking it....it's like someone turned on a switch.

Once the roots are established, you only need to water every 2-3 days. When you water, there should be some run-off, out the hole in the bucket. The more run-off the better, up to a point. If you water with a half gallon, you'd want to see maybe a cup of runoff.

Cannabis likes to dry out a bit between waterings...not to the point of stress, but it would rather be on the dry side than on the wet side.

Does that help?

I think the buds look fabulous, the leaves not so much.

I would listen to Setting Sun, but if isn't a big hassle, pull your plant from it's pot and check the roots or smell the runoff water for a "stink" that isn't the fert. Just following step one of Roseman's guide.

brother, hope you get it figured out. I know nothing of hydro yet other than what I have read, but hempy is kinda foreign to my brain. I get how it works but white soil....wth.

Re: MK-Ultra Hempy, C02, 1000watts.

Very helpful,I misunderstood your initial explanation. If it was even your post. I am still gathering info for when i finally get to grow, and can't thank you enough for all your help. Although now i'm pretty interested in learning about bato buckets.

That's a damn good idea! I don't think I've got a root issue, but it's good to rule it out. This plant just took off and is quite mature for its age. Southern Weed had a similar situation.

Bato buckets are just automated hempy buckets. I'll stick to hempy until I'm ready to go over 12 plants....which should be soon.

That looks like Calcium deficiency to me Doc.

If you've already flushed it, I would just give that one 1/2 strength nutes and see how it goes.

Hey there great grow! I really like hempy buckets, or the idea of it.

As to your leaf problem, I didnt read to see what you were feeding your plants and the EC/PPM of the solution but those leafs resemble a mag/cal deficiency. The tips do look like nute burn but then again Phosphorus deficiencies burn the leafs like that until they die. P def. would not be uncommon during bloom either.

Dont you just love diagnosing problems?

Dont rule out of MG def for sure though. MG def. start in older mature fan leafs and start at the tip and progress inward between the veins. Epsom salt will solve that or magIcal, my favorite.

Re: MK-Ultra Hempy, C02, 1000watts.

all good points botanist.

when in doubt, I prefer to err on the side of underfeeding.

I think it's safer and it avoids flushing if I was wrong.

If the plant doesn't improve soon, then you can increase the nutes and not much harm done, whereas an overnute situation can cause more damage and takes more work to recover from.

that's the tack I take when I'm not sure, but that's me. If you're confident enough about underfeeding being the issue, I'd take it from there.

Re: MK-Ultra Hempy, C02, 1000watts.

hey I just chimed in. I didnt read any past posts so I was just expressing my opinion. I wasnt calling anyone out, my bad. Good thread

 

[Setting Sun]

Re: MK-Ultra Hempy, C02, 1000watts.

Not at all man, you made some good points and observations, and you may very well be right.

I didn't think you were calling anyone out or being negative in any way.

maybe my tone seemed like I was miffed or something, but I wasn't at all. It's much harder to communicate well on forums than face-to-face.

No harm, no foul, brother

Great observations. It looks like a calcium deficiency to me....however:

1.) I've been using filtered tap water. Plenty of calcium.
2.) I've been feeding fairly aggressively, the highest PPM was about 1450. I'm using the FF trio with the addition of

8ml hygrozyme
5ml Canna boost or 6ml Atami Bloombastic or 1 1/2 tsp Hammerhead....never all 3.
Botanicare sweet.

There's lots of P,K, Mg in those products, which led me to believe that perhaps I locked out calcium...of maybe just burned them a bit. They were growing so damn fast with no trouble.

Here's what I'm going to do:

1.)stop with the Canna Boost. I had similar troubles on my last grow---got a great harvest with good tasting bud, but I could have done better. I don't know anyone else using Canna Boost....and no one else using my nutes has these problems. No more Canna.

2.)I"m going to feed them with a weaker nute solution....around 600ppm, using RO and 8ml of CalMag.

3.)There's still lots and lots of green on these plants. In fact, there are too many leaves IMO. If some of these great big fan leaves drop off, I don't think it will be a problem.

It's only one plant, that had a history of root trouble as a baby. This plant also has the most advanced bud development. Interesting.

The best thing about this grow is that it has impressed upon me how important the first 2 weeks of life are.

My reasoning for feeding them light is that if it is a deficiency, it will slowly get worse. If it's over feeding, they will slowly recover.
