I use a box saw to cut off the bottom third:
I put my cuttings in clear cups inside solid cups, so I can see the roots as they grow...I recommend it highly! I would have done all the split clones that way but I don't have that many clear cups.Pulling out the clones and shaking off the soil that way gives you a good chance to see how strong the roots are.
True! Well...the difference part anyway. I planted anything with roots.There's quite a difference across the group. Allows you to select the strongest one or two for potting up.
It would be if I had been Darwinistic, but I gave them all a fighting chance. I might end up keeping two or three of that entire flat!The scientific application of Darwinism. I like it!
Thank you VG! I can hardly wait for harvest day to see how many seeds I actually have. And then plant one to make sure it's viable...So happy that you got some seeds!! Well done, ol' chap!
Thanks Otter! I hope you had a good one.Awesome root pruning tutorial Shed! Thanks! Happy 4th!
Sorry about the rain Bode, but at least the plants are happy. Thanks!Highya ITS,
I agree with SO! Very nice segment on mother root pruning! Also, I hope you and yours have a nice 4th of July celebration! Raining on the East Coast. Oh, well. Happy Smokin'
Perseverance is right! It's so nice that something finally happened after all this time, even it was seeds on the unexpected plant.Congrats on the seeds, Shed! Perseverance pays off.
And, Happy Independence Day! I hope you're off doing something fun.
I'm good that way.I knew I saw this somewhere. It's like you read my GSC thread before posting your root pruning tutorial again.
Thanks 013! I'd never hit these kinds of page numbers without the great folks who subscribe here. I'd still be on page 10 talking to myself.I better jump in on this odd numbered milestone - congrats on 1300 pages Shed
Brilliant fix!I'll drop this update when most of you are sleeping, and if you're not already this might do the trick. :zzzzzz:
You may recall that I have had some trouble with the pH rising in my ProMix HP due to the high nitrate nitrogen content of my (and most) fertilizer. The way to lower it is by using a nutrient with ~30% ammoniacal nitrogen content for a couple of weeks. The roots will lower the pH for you as they take up that form of N.
science!
When I did my original slurry test on the Tin Can Kush and Red Dragon, I did not have the calibration fluid handy to reset the tester, and the results came back at 7.4. Way too high compared to the 5.5-6.0 range it's supposed to be.
For two weeks I've been running those two plants on a blend of nutes that include the ammoniacal N which should have lowered the pH of the ProMix, and this morning I tested them both again.
Here is the slurry test before I calibrated the pH pen. Red Dragon...6.4pH:

Tin Can Kush, also 6.4pH:

Better, but not ideal. Then I calibrated the pen using brand new 4.0 and 7.0 liquid.
Here is the actual RD pH:

And the TCK pH:

Perfecto (as my dad liked to say)! I'm back to using the MC-based mix, bumping the blended nutes even higher now for the final push in flower.
I'll try to get some plant pics in the morning. Morning!
And remember to calibrate your pH pens people.
Science FTW!science
Thanks Otter! The rep at ProMix gave that to me, and it works a charm every time.Brilliant fix!
Srsly.Science FTW!
Thanks BigD! I did the last pruning in early March, so it seems to last about 4 months. I wonder if that will be the same in soil as it was in ProMix, and if the time of year will also have a major effect on it.Nice update on your clones. I’ve seen your root cutting before, but it’s nice to see it again as a reminder. You should have a lot of new root tips for good growth.
In terms of the percentage of ammoniacal N in the nutes, I would guess that the less there is the longer it would take. In the meantime the plant isn't getting the nutes it needs from the substrate. Also, a higher percentage of nitrate N is better for the plants, as MrSauga posted here:Good to see your use of ammoniacal nitrogen lowered the pH for you. Does the ammoniacal nitrogen have to be at least 30% or is there a range like 30 +/- a certain amount?
If I had bought a 22lb bag of something that was 66% nitrate and 33% ammoniacal I would probably use that rather than MC as my normal base, but I've got sunk costs to deal with.The nitrogen should be mainly in the nitrate form as it provides more compact and controlled growth. More extensive leaf and stem growth occurs with ammoniacal and urea nitrogen. In general, to avoid excessive stretching and oversized leaves, more than 60 percent of the nitrogen provided to plants should be in the nitrate form. Ideally 70 to 80 percent as this will provide a moderate growth response and avoid overly large cannabis plants.
Yes, the pH was a lot lower after calibration, and the corrected pH was right in the range I was looking for. ProMix HP is set at the factory with a pH of 5.5-5.8 after two waterings, and I was told that anything above 6.2 would be considered high enough to need rectifying.So the pH of your soil is lower than you thought after calibration correct? Is the 5.7-5.9 within the range you were looking for?
I got these from Grandpa Tokin and it seems he got them from someone named Res1 in CO. So they very well might have been feminized seeds (since I got three females!).The seeds I have are Golden Goat x Tahoe OG But I was correct on where I got them. They came from Colorado. Res1 used to host a forum called “The Dank Den” it was a great place. When I started growing he helped me out a lot.
Thanks Carmen! Not much training on these other than topping and keeping the upper nodes flat while the lowers catch up...pretty much standard for me these days. And I hope I end up with at least a little pollen in addition to whatever seeds I get from that plant. I'd like to have a huge stash of Candida seeds to be able to get to folks in need.Wow, it feels like just the other day they were sprouts. They look beautiful. I'm sorry I missed their training. Good luck with collecting that pollen and treating for pm, Shed.
Thanks Rexer! I'm really happy that the purpling is just beautiful and not some sort of deficiency in the making, like I thought it was when it started.Absolutely beautiful, that Red Dragon pic especially is stunning!
FTFY!Tuesday update will be all plant pics, no meters or scales!
Beautiful buds on that RD My son's RD has not started flowering yet. I sure hope his looks like that.Here is the Red Dragon:
I really like the bud structure of that plant. Those tops - and there are quite the many - are all shaping up nicely.And the Tin Can Kush:
So the seeds that you did get, came from the STS plant that self seeded... did I understand that correctly?Neither of them show any signs of seeds even though I shook the STS one over them almost daily back when they had pistils.
Deal away. I think you know how to correct things now so it shouldn't matter what you use. Just means more thinking in the long run, and using that stupid pH pen.If I had bought a 22lb bag of something that was 66% nitrate and 33% ammoniacal I would probably use that rather than MC as my normal base, but I've got sunk costs to deal with.
LOL! I'll use the bypass lane for the scales from now on.FTFY!
Thanks Carcass, but this plant is nowhere near as gorgeous as your runaway POTM winner.Red Dragon's a real looker- and the TCK is a close second!
Beautiful leaf coloring on the RD -reminds me of the SSH a few months back...
Thank you Reave! The older I get, the less I like the heat. Where I live I'm really only good in the shade.Looking good shed. Weather is looking nice your way too. And that July weekend worked out nicely. Bring on the heat.
I hope so! I'm looking forward to pics of that plant come August...Beautiful buds on that RD My son's RD has started flowering yet. I sure hope his looks like that.
Thanks BL, and with another 35 days left (or more as we outsiders wait for more amber) I'm hoping it has a lot of bulking to do!I really like the bud structure of that plant. Those tops - and there are quite the many - are all shaping up nicely.
Indeed. Though I never saw any pollen anywhere, there must have been enough to pollinate some of the nearby pistils.So the seeds that you did get, came from the STS plant that self seeded... did I understand that correctly?
If I can get soil to work as a medium, maybe the pH drift won't be as much of a problem as it was with the old ProMix HP. But if I can't get soil to work (I have given myself a year-end deadline), then I'll be back to peat-based.Deal away. I think you know how to correct things now so it shouldn't matter what you use. Just means more thinking in the long run, and using that stupid pH pen.
I'll try to gauge the end-weight of the branches on both tonight and see. I get the feeling it just had a wider structure generally, which puts more weight over nothing. It started flopping pretty early on.The RD floppiness. Is that from heavy buds? I ask because it's something I'm trying to understand. Regardless of what is in the mix, heavy buds will flop a plant pretty quick.
You can't imagine how hard it was not to make a joke about this!which puts more weight over nothing. It started flopping pretty early on.
