The coming vert farm will be a sight to see I can assure you!
Really looking forward to this since you have unlimited plant #s.
You can fit 64 cuttings in a 4x4x30" tall space around 1 600w. 1 plant per ft2 with next row of plants 10" above.
A 600w bulb makes 90,000 lumens, not bad.
The sun makes 98000 lumens per m2.
People claim yeilds of 2lbs per 600w.
896g ÷ 600 = 1.4933333333 GPW
People have also claimed 2.678lbs per 600w.
1200g ÷ 600 = 2 GPW
Thanks DHF, you have contributed alot of great information.
Here is the link to heath's flooded tube vertical journal, more great info.
Page 36 about midway down vert farmer has great contributions.
I really like the 8 trees around 2 stacked 600w.
1792g (4lb) ÷ 1200 = 1.4933333333 GPW
This seems to be be the more economical way in terms of effort to setup and maintain. Although, you are limited in terms of potential max yeild per 4x4 floor space to around 4lbs, maybe more once really dialed.
Coliseum SOG you can add more shelfs, plants and 600w lights going upward to increase potential 4x4 floor space yeild.
A friend of mine had one of these systems, coliseum by growco.
Keep on kicking ass man!
