Thinking of trying indoor this fall, first step lighting?

[EugeneDebs420]

Any 480-600w bar light will get the job done in a 4x4, I run a mars fce4800 and a samphon 480w in my 8x4 they both do the job great and don’t create to much heat. For 5x5 600-720w would be plenty. You don’t have to go super expensive on the lights you’re gonna find surprise expenses elsewhere on you first indoor grow environmental optimization is way more important than light brand (and usually where those surprise expenses come in) heating, cooling, humidifying, dehumidifying, ventilation all equally as important as lighting.
