m0useanswered grow question 2 months ago I would do 2 strains with 2 plants each OR 1 strain with 4 plants, doing multiple strains can be a bitch especially with Autos as you can't use HST on them as effectively as photoperiods to control height.
I have done a tent of 6 different autos before, and one tent with of a bunch of photos. The photo tent worked out better. Autos are great outdoors IMO, indoors unless your only running 1 plants I think there is to much variables unless their genetics are locked in. But that's not to common.
In the end its your choice. Feeding Amendments be them organic or not, take time and a bit more understanding of how they work in the soil to feed the plant. If feeding with liquid nutrients they are going to outperform almost always as its ease of access to the plant is a huge bonus in smaller pots. And liquid nutrients can be organic or synthetic. pretty much all the samething. Biobuzz vs TA are good examples of organic vs synthetic on liquid side of things, both produce nice plants.
Best cost point is dry and mixing it yourself. Jacks is a good brand for that.
Good Luck!
