Autos, week 4-5 from seed, preflowers barely showing.
Time to go HPS?
Do HPS lamps run hotter than MH - If so how much higher should I raise them (MH now @ ~22')
Any other thoughts/comments?
edited and corrected
Has anyone used these bulbs for veg and/or flowering? It says there good for all stages of growth but those temps seem high from veg usually being around 4200 and flowering being at around 2100 kelvin temps..
The other day I was having a conversation with another grower I know about, what else, growing! In particular we were discussing grow lights and we had a bit of a disagreement over what was the best in terms of actual performance, overall cost, cost compared to performance, and so on...
