I am currently running 3000 watts for personal use...but i know its not the lights.
HPS is awesome...those that shit on them never grew with one..and a buster hood the heat goes straight outside....less heat than a board with a meawell in the room.. for sure.
Strips seem to outperform boards. Get them from Peter at growadady...what a deal...the man knows his shit and the price is crazy.
Cobs are better than strips or boards...But i love the mismash of what became everything...when i had 300 bucks i got that board...mejiu for 250 etc
Crazy.
They all grow. Grow it !!
