So I figure my lights at 300w right now. I have 4 cobs being driven @700ma from my wall @110v im assuming this is right, I went (W)=(V)(A) so (W)=(110)(.700) any LED guys out there to verify this?
Hi Brokeleg, your math is good (W)=(V)(A) but I'm not sure if ur cobs are 110v each. Is this a cumulative series wired voltage? In this case you should have 77W. For a detailed math I'd need cobs and driver model. Thx
No it's not like that. Just like your phone charger works at a reduced voltage (usually 5 volts) even though it's plugged at 110V, your lights works at a reduced voltage (how much depends on the one you are using)
Hi @Brokeleg! Indeed, that would make 308W but it depends on your resistance and the voltage drop. I recommend to get a smart-plug so you'll be able to track your energy consumption efficiently. Happy growing!
@Brokeleg,that is what i think exactly to much water. They started to droop in week 5. i hope she recovers. In worst case repot her. and give her new drye r soil. but try at first to reduce watering. Because autos dont like transplanting . But they also dont like it to have wet roots. they may molder
@Larimar, yeah they havent been looking great i raised my light, and put a dimmer on it. Dont know if this is from too much light or maybe to much water?
Next time if it’s in door keep it indoors. I’ve seen so many growers ruin there crops from putting their plant out in the garden for a few days of sun, then putting vback in the tent and infecting there whole grow area. Stay indoors dude✌️🏻
