My HTGSupply 250w ballast is now a 250w paperweight. I need to replace it, but I'm poor. What is the best bang for your buck? I'd like to spend as little money as possible, preferably less than $100. What are you thoughts?
Nothing against MH bulbs (I have two setups with a 250w and a 600w), but one thing I figured out early on was MH bulbs actually increase the nutrient uptake of the plants under it. Not that that's necessarily a bad thing, just have to pay attention to them to look for signs of deficiency and fertilize a slightly more frequently than normal. Just a fun fact for yaalkhall said:But, I have to ask; why HPS and not a full-spectrum HID, i.e. Metal Halide?
