Hi, I want to build a SOG hydro system, for around 30 inch tall plants. I was trying to decide between 6" tubes with netpots in them, or a dutch-bucket system with either 1- or 2-gallon pots. Both would use grow rocks.
If I used the tubes, a 5" netcup would be the bigest that would fit, vs the 1- or 2-gallon pots if the dutch-buckets. You mentioned that a 3 1/2" netpot would be the minimum for a 30" plant, but if there was no size limit, what would be the ideal pot for that size plant? Like, would a 1 gallon pot with rocks be better than the 5? netpot, and would a 2-gallon pot be even better? Or would the extra pot space be wasted with that small of a plant?
BTW, if I did use aero tubes with 5? netpots, would there be any point to using aero sprayers on the sides of the netpots or would continuous drip be just as good (like would the roots all be inside the netpot with not that much outside it to spray)?
thanks
