Better find a source of calcium. Epsom salt is magnesium sulfate.
:passitleft:

Thanks Felipe, I haven’t decided yet, but this crossed my mind yesterday, and I’m glad you jiggled it again. I’ve always thought of it as I t’s calcium that makes the flowers so sweet.

:passitleft:

I wish I didn’t have 20lbs of the old forumla still.

:passitleft:

And I’m glad I don’t. Lol!

How long can you hold premixed MC around?

I currently use an organic veg nute, so there is practically no hold time. It will start growing in my gallon jug fairly quickly. Once it’s in the pots, I don’t worry so much because that’s the bacteria and fungi I want to grow, and my plants take it up fairly quickly - I feed about every two to three days.

I try not to keep any premixed around unless I’m dumping it into the pot the next day. My current Carnival is a good example. I mix three quarts. She drinks just over two quarts and I set aside the remaining to pour into her pot the next morning. I could just as easily water her 1/2 gallon a day and get more flush, but she’s too big to move easily, strung up for support as she finishes, and I don’t want to have much runoff in the saucer.



I know how much water the plants need. I mix up for each plant or group getting the same drench.

Stan... I haven’t heard of anyone using Jack’s for hempy. Is it at all adaptable to hydro?

People have been using the brand for years in drain-to-waste hydroponics setups. But "Jack's" isn't a product, it's a product line, and some products might be more useful in a hydroponic environment than others. EDIT: And quite an extensive product line at that, lol. If I didn't just miscount, they have 86 different products listed on their webpage (Jack's Classic products, Jack's Professional, and Jack's Professional Specialty Elements).

Jack's Professional 5-11-26, their calcium nitrate product, and Epsom salt is a common combination for people who use the brand in hydroponics. I've also seen mention of Jack's Classic 5-12-26 Hydroponic / Jack's 15-0-0 Cal-Trate (calcium nitrate) / Jack's Classic 10-30-20 Blossom Booster (for those who use flowering "boosters"). A web search such as "Jack's hydroponics" (sans quotation marks) would undoubtedly bring up many results, and probably show you more product combinations that are in use (and at what ratios).
 
Just get yourself a 1.5lb box of Miracle Grow granular All Purpose Plant Food at Wal-Mart when they close it out each fall. I got 3 boxes this fall for $1.49 per box...….regularly $5.94 a box
 
I've looked into using Jack's. I was particularly interested in the bloom booster's npk as a possible stand alone, until I investigated and found they require a cal and mg supplement... not stand alone enough for me.

I've seen some beautiful plants grown with MG

Yeah most folks probably expect a flowering supplement to get used in concert with a nutrient program that is correct in its other aspects, lol. But with such a huge number of products, you could try sending them an email with your exact requirements - they probably have at least one employee whose sole job is to help people select the right product for the job. Maybe you could get the person to send you a set of samples to try against whatever you have now. Wouldn't be the first time such a thing has happened.
 
Hempy rocks! But then we all knew that. :laughtwo:

Brix has struggled for confidence in cloning and seed germination, when it suddenly occurred to him to add a seeding mat to the process.

Boom! Roots!




A Northern Lights seed sprung up too! :woohoo:


That makes four plants now growing hempy in Brix’s garden, along with my two in the corner,


....so a majority of what’s in here at the moment is hempy. :slide:




I fly out for a quick trip on Saturday, so there’ll be a 10-day gap in pictures. Prepare to be stunned when I get back. :laughtwo:
 
After all of this rockwool is gone I am switching to perlite germination. Here is my current garden nonetheless.






I think everyone is happy at 1/2 tsp each per gallon, Mega-Crop and Maxibloom, ph right about 5.5, fed daily. Going to ride this grow out with that ratio. After this round I have to purchase nutes again... guess we will see what happens.

The male on the left is gone as of 30 mins ago. I did cut off one grow shoot and threw it in a cup of water just to see if it will open up and drop some pollen. Little side experiment.
 
So.... this photo has been tickling my brain. I want to talk about it, because it forms an important lesson in the hempy cloning world. Thanks for the source SS. It's a clone in BN's garden.

There could be a few things that caused all the yellowing. I'd totally clip of all those completely yellow leaves and the yellow parts of the other leaves.... they're just forming a mold risk.... not why I'm here tho. It could have been high nutes or temps, or drying them out too much, but I bet it was getting them too wet.
One of the worst things I can do to my clones under covers is to get the leaves wet in any way. The lingering water seems to block respiration and cause the death. Keeping covers on them ramps the humidity up to 100%, and the babies are getting all their water thru respiration. As an added screw-you, mold starts so fast under the domes.
Like previously stated, it might have been something else, but this is totally what they look like in my world when I've let water linger on the leaves and I thought I'd take the opportunity to speak about the issue with it. Look at that cute new growth popping up thru the center... fun!

This wasn't a hempy clone, it was a regular old Rapid Rooter clone. The one hempy clone I have taken showed absolutely no yellowing. I think this Rapid Rooter clone was a bit too wet and a bit too cold, but that's just a guess. I have more hempy clones on the horizon though, it worked really well.

Excellent!
No misting under the hempy cover baby. If the cover gets drippy, vent it a touch to let that moisture dry, then re-cover. If you're using a plastic bag, just turn it inside out and the dry part will be on the inside.
 
A little experiment. Hat tip @Tead for a whole lot of leg work.

Dat's awesome stuff baby!
Tippy tho... be super careful. I bet you end up with some sort of footing to help with that. Mine were 6" round but I still had to be careful when the girls got big. If you end up with leaking around the base cap, don't be tempted to use normal silicone sealant... only marine grade will work.

Definitely wobbly. I stood in the isle at the hardware store and seen the threaded 3 inch plugs and thought I could embed those in some wood since there are hex head if I used a female adapter. I might do something different in the future.

The thought behind this test was to go cheap as possible but be effective in the effort. I plan on vegging for another week and I am putting these clones strain into the flower tent. I want to see how much yield is possible from this method. More like a sea of green hempy style. I did a mix of vermiculite and perlite, but thought I should just go straight perlite after the deed was done. I am hoping that they will be around 18" tall with a nice size nug on the end and a trellis net should suffice for stability. I mocked up a foot print and I could get a minimum of 20 of these in my 2x4 tent. We will see how these go before I commit.

I did however put water in the tube prior to filling with medium. The goal was to see how much liquid the res would hold. I poured it into a measuring cup after it dribbled out. It was exactly 1 cup. So when I go to water I am think of dumping 1 solo cup worth of nutes down and walk away.
 
I’m having good luck with my cheap 2L nursery pots. I taped the drainage holes on the bottom with waterproof tape, then melted my hole in the side. Pots were $1 each. Tape was $15, but it will last a decade.

The pic is from two weeks ago, but I wanted a pic that sows the pots.

Way to go BigBear! Frugality wins again. :high-five: And Buck..... :thumb: I’m waiting to see what you do to stabilize the field. You want to avoid any tendency to go all domino. Lol!

When I ran the small pots that only held about 2 cups of perlite I pulled an average of one ounce per plant, even taking into consideration the Mendocino Underdog that seeded herself and gave up nothing. I think you’ll be surprised Buck. Until the roots hit the res you might want to tape the holes and fill a little deeper, the way beez does, but then again, if your roots are into the 8-12” range you’re into the feeding zone.

In my garden, when they got to around halfway into flower I’d stop worrying about runoff anyway, so the 1/2 cup dump and run is my modus operandi anyway. I want to see how well that works from start to finish. Thanks for being the guide. :hugs:
 
Things are filling in nicely. Lava rock hempys are doing the trick. 1/2tsp Mega-Crop and 1/2tsp Maxibloom per gallon.
