I built a 4 in 1 big box...1 for clones/veg, 1 for veg and 2 for flowering...all in one. (8'x2'x7' each box is 4'x2'x40 inches)
Every 35 days the plants get switched to the next box...perpetual grow with an up to 70 day max for flower cycle.
Each box is cut off from the others (top divider not in pic) and can set lights and timers separately.
Pic is from awhile back when I was building and painting, but it may give you an idea.
Dude HOW!!?? That's insane man you did an amazing job!! But HOW do you flower a plant in such a small space!?? I do mainly photo but this is a pic of an AUTOflower I have right now that is still taking up most of my 4'×4', my photos are much larger so I just cant wrap my head around the logistics lol. And what kind of medium are you in? I'm in 5g DWC buckets but I think I'll try to switch to a lower height rez. Do you have enough room for decent root growth?
I built wired scrog nets that are held up by the plants and don't need to be tied to the pot or anything. It helps to limit the height...usually about 10-12" in height and when strong enough I take out the temp legs you see in the pic.
And when it flowers...about week 4 or 5 I think...no more legs.
I use an under the bed tote (66 liters) and put pumps and everything inside...no holes/leaks...7" in height for +7 gal per plant basically....I do 2 plants at a time...every 35 days or so.
I'm still working on it...or building as I go, but it does work.
