Hi folks, I am a n00b and thinking about setting up Aero/Nft. I saw great tutorial made by StinkBud. Basically, he advises to have an aero-cloner, aero-vegger, and 3 aero flowering apparatuses; 5 altogether. I works on 3 week cycles: Clones 3 weeks, then put to vegger for 3 weeks, and then to flowering for 8-9 weeks -- note: you have 3 flowering aeros so you can put your veggies to flower every 3 weeks. Now, here is where the problem lies....He says to clean out the reservoirs every end of the cycle. That simple, I get that. You clean out the cloner and vegger every 3 weeks (end of cycle). But then the flowers?? you put them to flower. However, they stay in the very same apparatus for 8-9 weeks. He says you clean out the flower reservoir when you take 'em out. But really? Can it go for 2 months with the same water? All you do is add water and nutes to maintain PPMs?? Thanks everyone.
