I'm building a growbox out of 2 30 gallon rubbermaid containers for 4-5 plants. I am about to buy either a 70w HPS light to hang from the top and put a few 2100k CFLs in the box as well. Or a 150w HPS to put in the box. The containers will be stacked on top of one another. There will be a rectangle cut in the bottom with tower fan pushing air in, and a computer fan at the top pushing air out through a carbon filter. My question is which will be cooler. Any suggestions are much appreciated.
SparkNotes: 70w HPS + 4 CFLs or 150w HPS. Which will be less likely to melt the plastic.
