Meaning the main chamber is 2x4 or 3x3? Either way. Aim for actual wattage of 50/Sq ft… so a 2x4 or 3x3 would want ~300 watts. Ofc that number will decrease as technology increases. My flower tent is a 2x4 with a sf2000, 250 max draw. If I were to do it all over I’d have built my own hlg equivalent, since it’s cheaper than the sf2000 to do so.
Spider farmer is definitely the up and coming budget brand. If I ever buy a light that isn’t HLG in the future you bet it’ll be another sf. Besides wiring, that’s all you need to make a light better, brighter, stronger than the sf2000 which costs $70 more.
Crazy how if you do you’re own wiring you can save butt loads. Where name brand becomes cheaper than off brand…
