Not much at all has long has you have a fan blowing over them,if anything you will be adding heat.They really are great lights .I would love to try another grow ,but with a sf4000 over one plant,im thinking it could produce a very nice weight.The final product was really nice.The worse out of them all was the exodus ,it was growing under a scrog tale for the first 2 weeks of flower.The buds are solid ,hoping i can get a nice bit of bud from tent grow.Dont think that auto is gonna do much ,its started to flower to small tbh.How much heat do they put out?
So with no fresh air whats your room temp just running lights?There is no denying ,that these lights are great in veg has well has flower.Auto is getting pulled ,its flowering its way to small .I would rather give sugar factory more room ,than get a oz if that of a plant.Front 4 Sugar factory ,Auto dj shorts blueberry x greenhouse northern lights View attachment 4769046View attachment 4769047View attachment 4769048
