The age old question HPS, MH vs LED

Grow So High

I switched from a 1000w HPS to 2 leds that total 640 true watts for this run due to heat issues and to bring back my electric bill a little. Haven’t noticed much of a difference tbh. HPS had a slightly faster growth time but can’t tell the difference in bud and resin production. Just buy from good quality brands even if they are “blurple” lol

When everyone is talking about HPS are we talking about Ceramic HPS?? Because of power and heat nothing beats those right??

yeah but isnt the heat from HPS already enough... more only equals to less PAR... the IR from CHPS is immense and will boil the top leaves
