Unfortunately I can't do this anymore since I'm using a no-till living soil box nowThey are looking good. I too have struggled with different growth growing more than one strain. I’m in soil so I can give my short plants a little booster chair to the lights to even things up. Ima;ways plan just one strain but it doesn’t always work out that way
Growing different strains simultaneously is something you need to know your strains for.
While this is hard when growing from seeds, clones you already have grown once are quite easy to handle imho.
The only strain I know of my three is the Amnesia Core Cut on the right side. It's a super silver haze pheno of which clones are available in Europe since 1994.
The left ones are said to be Bruce Banner... which I first read about in this OF thread and the middle ones are Pineapple Punch, noname selection of the growshop which sells the clones in Austria. Probably very much on the indica side.
