Hi I'm saving up for a better flowering setup...looking to do 2 units of SF4000 in one 4x4 or 5x5 tent. I have the SF2000 and a 2x4x5ft tall tent been using as a veg/clones tent. Wanted opinions from more experienced players out here.
SF4000
Spectrum: 660-665nm,3000K,5000K, IR 760nm
PAR: 1217umol/s
Lux: 79296Lm±5%@AC120V
Draw: 456.9W±5%@AC120V
Light Size: 648mm x 536mm x 59mm
Based on the size dimensions I can to fit two SF4000 lights (0.648m x 1.072m) in at least a 4x4.
For 914W power draw:
(2x79296Lm)/16 = 9,912 Lumens/sqft for a 4x4.
(2x79296Lm)/25 = 6,344 Lumens/sqft for a 5x5.
SF2000 in the 2x4 would run pretty warm temps. I'm concerned this might be too much heat. Should I get the two and up the CFM air output? 12 plant limit, I have 150 seeds, and want to get this right. I don't want any fluff in my buds! Lol
Would you go for the two in a 4x4 for max light intensity? Or in a 5x5 with some space between the lights for better heat/air circulation? Or one SF4000?
Let me know what you think, thanks!
