pretty cool man, took me a minute of staring at it to get it, but i do now.
are you going back to colosseum instead of stacks? what are your thoughts on this since you've got your new system.
i've been meaning to build some slanted racks like that for my 42x18" trays. i think the plants would like that better than me trying to push them out. i was thinking something not so solid(1x8 with a 2x4 on the lip) but heath's design is really strong and i don't need any more accidents.
i think plant #'s vs. veg time and having the environment dialed are the two most important thing in maximizing gpw all other things being equal...
colosseum is the king of vert but its not for large scale though...
edit:
this is what im talking bout
