Well... I believe you veg longer. I think these could get bigger and yield more but I'm a fan of diversity/variety so I'm targeting performance for my needs.
A 10gl soil softpot w 27gl rez would get very big if vegged longer than a few weeks.
I built that one in the pic to hold two 5gl softpot setups. I use the doubles for short, slow growing indica's and a single 10gl for hybrids etc...
I'm also lowering my max water level a tad to encourage more root growth from the wick
Yeah, I veg longer- because bare root hydro in hydroton rocks with ebb n flood tables were giving me fits. Then I had clumps of leftover dead roots fuck up my RDWC.
I did get that under control, but if I'm going to model commercial facilities, then I need to use their methods. In Colorado, most use coco DTW, but it's not for the reasons you might think; rather, they're unable to pour spent nutes down the drain and therefore are forced to put them into coco instead. This way, they can toss the whole thing as dry waste instead of contaminated water.
Besides, if the client wants to use coco, I need to be ready, willing and able to accommodate them. So far, the veg in Tupur rocks and the substrate is very forgiving and productive.
