This is my first time writing and my first time growing as well. I have a couple of bagseed plants and they have been growing about 3 weeks. I recently bought a 70 watt hps lamp that works fine and my plants have been doing really well under this light. I feel in a couple weeks that i may want to upgrade to a better, more powerful light, and conveniently enough my friend has a ballast that he will loan me for free. It is a 400 "volt" general electric ballast for street lights. My friend said the street light it came off of was a high pressure sodium, but the ballast is made for flourescent lights(or says the guy at lowes). So, this is what i want to do, and I hope that it works out. I am thinking about taking apart my 70 watt lamp, hooking it up to my new ballast and putting a 400 watt hps bulb in.
So these are my questions...
1. Can i connect a 400 volt flourescent ballast to a 400 watt hps bulb (keeping in mind it did come off an HPS street light)
2. Will the lamp be able to take a 400 volt charge with the support of the ballast? Or do i need to buy a new lamp as well?
3. Will a 70 watt HPS lamp be enough to grow two plants, if not then how many watts or lamps should i get?
4. What are the results like when vegging a plant with HPS lights?
