No problem, I love talking about grows
Yea the roots grow both out the bottom and up the sides as far as I put LECA in the tray. You can also see where they come out above the LECA but they prune themselves off.
My plan was to start the plants in a 1gal and then place that inside a 5gal but I really don't see a need, at least yet.
The current idea for the next grow will be clones from Tent A and either test GH Flora Trio against Dyna- Gro by using a separate res for each tray or more likely right now run 3 clones i ea in 1gal, 2gal, 5gal pots and see if there's a difference.
I've pretty much got both tents set up for the "gen 2".build which means I can start trying some experiments and fine tuning as well as start planning the next gen for the tents, custom DIY frame work to hold the trays, ScrOG, lights is the main part as well as some system for easier draining and filling of the reservoir.
The other decision I'm still wrestling with is do I want to run a nursery in one tent or run both as I do now one in flower, one in veg. I'm leaning towards sticking to what I do now esp. if the ScrOG runs well for me and after I try running a 2 or more strain grow under it. If I can run multiple strains well under the ScrOG I can just clone from the current veg tent flip the lights to flower and start vegging the clones in the tent that just finished flowering. Fortunately I don't really need to decide right away, but I'd like to get back to not dealing with seeds every grow.
