Harvesting 1 out of 2 plants sharing the same reservoir

No, your drying and growing tents require two separate environments. For drying you want to chop and hang the whole plant in a dark room that's 60°f and 60% RH. Your grow tent needs higher temps and lower humidity during bloom. Your plants will dry out way too fast if you try to dry them in your grow tent and that will lock in chlorophyll and other unwanted chemicals before the aerobic bacteria has a chance to break it down. You'll end up with harsh tasting smoke that won't burn well. Just set up a closet or something to dry your plants in.

Ola amigo tudo bem? E simples, uma caixa de tenis ou uma caixa maior, fazes furos em volta da caixa. Colocas algo a passar de uma lado ao outro, como se fosses estender a roupa xD E colocas la as buds, fechas bem e tens o problema resolvido. no meu cultivo anterior fiz isso e correr tudo bem :) Parabéns pelo cultivo e abraço

Thanks for the insight. I definitely didn't think this through before growing two strains in one reservoir. Lesson learned. Now I just need to figure out how to flush and dry my first harvest.

I would NOT dry in your grow tent. You do not want photosynthesis occurring after harvest. I have a separate tent just for drying which makes it easy to harvest one plant sooner than the others. I would not flush in a system like yours. Switching to just water won't hurt but it certainly will not help the plant that is still trying to fatten it's flowers. It's one reason why growing different varieties is not the best in a shared hydro system. If growing in soil it's much easier as you can give each plant what it needs. In your case is there any way you can rig a temporary water only system for the plant you intend to harvest?
