Alright. So I'm going to need a ballast for both 100 watt HPS & MH.
Do you have any recommendations on where to look? There are no local garden stores.
I just ordered two lightbulbs: a 100 watt HPS and 100 watt MH. The directions mention a ballast. They are sized to fit a regular socket..
Are these needed? I don't want to catch anything on fire.
What kind do I need to get and where can I get them?
Thanks for the help in advanced.
