room temp in the 70's. company told me to switch out the power supply with one of my other lights to see if its the power supply vs the cob.. havnt got around to it yet hah
Had a w90 on my seedlings 24 hr light cycle for a about a month so far and came home this morning to find the cob not putting off any light... the fan was still working but no light :( hope its not broke already.. i sent a message to company just now. I bought 8 of these things, but only had one...
