In so many words I was trying to say that you can't cover that area for that amount of money.
The ufos barely do 4 sqft. The Spectra 280W for 650 does 16 square feet, So with both combined your still short and over budget.
You can cop 2 ISIS panels which my and maybe a UFO just for kicks (Maybe the UFO as side lighting - stretching the LED's thin will def have negative consequences on your penetration). To fully and effectively cover 24 sqft in full flower (which is when it counts) you will need to spend over 800 bucks to do it right.
Either shrink the grow area or enlarge the budget. What ever you do, don't cheap out as that usually leads to dissatisfaction.
If your talking about spending 1000 the doors blow wide open. 2-3 ISIS 170W panels, 4 240w Blackstars (24 sqft on the money), 1 ISIS and 1 357 Magnum, 2 Spectra 120W and a UFO, the list goes on.
I would just stray away from a solution that calls for cutting corners. Make it a 4x4 room first, cop a couple of ISIS, or 3x240W Blackstars, or the 280W spectra, or A magnum and try that out first. Get the money from that and start the 24 sqft room up properly.
can you guys please help me. my grow space is 4.5' x 5' x 7(WxLxH). can you guys tell me what lights would be decent from this in a price range of 800? i see that spectra, 357 mag and others are decent. i read that blackstar is decent, then i hear it isnt.. im confused... i have 800 to spend and want invest it the best that i can, please give me opinions on what i could get. thanks!
