Hellou , i have a question . Which is the best LED for indoor grow?? Lumatek zeus 600w or Spider farmer sf4000

You’re gonna get better even light distribution with an option like the zeus.. so you can fill out your area more evenly. The Mars hydro FC4800 is an top end choice for a fraction of the cost of the lumatek. I’d go with a bar light set up like that

Giving those two option in a 1.2m square are (4ft x4ft) the Zeus is the better option with more yield potential as it’s a larger footprint and also 230w more powerful. The Zeus could probably do a 1.5 meter square area to be honest. A better option than the sf4000 would be the Mars FC4800, I am using one and it really is impressive. Feel free to check my diary to see it in action.

Well, I'm a bit new to some of this, but from what I see, I think it depends on if you plan to fill the tent or just grow a couple of plants in the center of the tent. The SF 4000 has better light closer to the center while the Lumatek Zeus 600w has more consistent light all the way to the edges. Just looking at the Light maps at 18" and 16" respectively. I personally have only used the Spider Farmer SF-2000, and its been good to me so far.
