laylow - I think you should give it a go, once you see the growth rate you'll be sold.

nice garden!
other options:
* hand watering to eliminate hoses = reduce yield by 10% min unless you're prepared for 5 feeds a cycle at peak flower, the feed has to be fed gently so it doesn't wash through, say 1 minute/plant = at least 20 minutes by the time you've started and cleared up, 5 times a cycle = 100 minutes a cycle ....not for me
* sealing the bottom catch tray so that run-off is used by the plants, and not wasted
= 1) N/P/K of what? Fresh feed will definitely contain what your plant wants, add some recycled and you're adding what it's already decided it didn't want, why should it want a stronger feed of something it's already decided it didn't need
=2) Removal of salts and cleansing of roots
=3) No chance of spreading pythium from 1 plant to the whole lot as I found out, this
Went to this in 5 days, all the other roots are dead so it's just the 'main' ones left
Run off can successfully be used in the vegetable garden in the summer with old coco, we grew enough beans/peas/squash to feed 5 people
* placing wheels onto the bottom catch (wooden tray build), and cutting off corners to make an octogon-or circular-shaped tray, so that it can be spun around. this will give you access to the all of the plants all of the tyme, w/out restricted access to the far corners - why bother, you'll tangle your drip lines, you shouldn't rotate them for 'even coverage' or they'll end up with airy buds and after 4 weeks you don't want to be moving them about
* lowering one of the lites, so that they become staggered and off-set. this will provide greater overall coverage & make it so they dont shine in to ea other. plants like different angles of lite.... without computer modelling the light waves could actually interfere with each other, so let's Keep It Simple

keep having fun
So.....
HGO Hows the damn plants??????
