I decided to just go all the way into the 7 gallons. I was pretty surprised at how little root development there was in the (slight less than) gallon pots. Should have taken a picture. Not like alarming or anything, but not circling by any means. I think maybe it’s preferable to see some circling before transplanting?
Thanks again for everyone’s support today!
Didn’t add any epsom into the mix. I figure that might straighten itself out with the fresh soil, but something I will be keeping a close eye one. I doubled my
calmag addition.
I think my new topic of inquiry is figuring out when to flip. I’m going to swap the metal halide for the HPS for a day soon and record leaf temperatures at varying temps/humidities and light distances to the canopy. I’m pretty sure I’ll be safe at 16” but I want to be somewhat scientific about it within my climate. Right now the leaf temps under the tippy top of the canopy max out at 1 degree above ambient temps. Pretty happy with that. I expect that will rise with the addition of humidity from the new big pots. More humidity means higher leaf temps usually.
So the strain is Grimm Truffles. It’s a cross between white truffles and cindarella 99. Cindy supposedly stretches 3-5x. Truffles probably a lot less. I can’t seem to figure out a ballpark estimate of how topping effects stretch. The breeder (Brother’s Grimm) claimed on the phone that I can expect a 2x stretch. I don’t know if I believe that and either way I will be wise to account for a 2.5x stretch. Does that sound reasonable? If I need to assume 3x, so be it. I just don’t know but I’m certainly going to aim for my target of 42” tall plants, from the soil surface, or roughly 52” from the floor. Any advice? These plants are pretty damn compact. It seems like a lot of growth so far for what amounts to about 7” tall plants currently. I’m not going to scrog them. I’ll probably just do some light LST and support the tops with yo-yo clips if and when that becomes necessary. Gonna lollipop the lower 1/3 or so, maybe a teeny touch more than 1/3. I topped above the 3rd node and have a nice even canopy developing.
So for a 2.5x stretch factor, I’m looking at flipping at 17” tall. 21” for a 2x stretch, or 14” if you guys think she may go for a triple stretch. Any words of wisdom for me?
