Hi I have a question about heat. I'm looking at a 150W HPS on ebay from htgsupply and I really want to get it. My question is how much heat will it produce? It has a glass insert for the hood. Here is my closet grow. I have 221W in my closet right now on one plant. Set up like this
View attachment 1156649. Right now I can get my temps down to around 70, probably lower. You can get at least 2 plants under one light right? How much warmer will the HPS be with the glass and vented hood and the fan blowing across the canopy?
