New grower here and need some help if possible. I plan on getting a 4x8 tent with 2 maxsisun pb4000 is that correct? They say 1 pb4000 for a 4x4 so 2 for a 4x8 should work right?

That light is only 1.9 umol / j efficiency. You would be better off with this one. It has an efficiency of 2.5 umol/ j. That translates to almost 25% more light per watt.

Definitely 2. 2 only puts you at about 25 watts a foot. That will work with the high efficiency boards but 30-35 is better.

Sorry man, I didn’t mean to sound harsh. When looking at lights look for Samsung lm301h or b diodes and meanwell drivers. They are the most efficient and have a good spectrum. You also want some extra red diodes in there to help with flower.
to know how powerful a light is look at how many watts they actually use from the wall. Most 1000 lights are 100-150 actual. The 600s are usually 65 watts or so.

it’s cool man I know when you hear new people talk we sound stupid. I’m just really confused right now. I’ve been good up until this point picking out lights. I want a 4x8 tent which would be set up in basement. Now, my budget for lights is around 1,000 give or take hopefully cheaper. It’s a first grow so I’m ok with not the top of the line lights but I do want something that I will be able to yield something good. Thanks for helping a brother out man.
