I don't know much either to be honest, but the green wire was grounded to the hood from the factory when I hacked it up for my cool tube. So it's probably good enough.Your ground wire needs to be connected to something that runs into the ground, other wise it won't do anything when the time comes. I don't think grounding it on your hood, which is connected to your ducting, is the best idea. I may be wrong though, it's been a good while since i took electricity 101.
Correct! I hacked it up with a dremel lol but I reused the wiring and socket.When you buy one of those euro wing reflector's (the cheap bendy ones) they come grounded to the hood so I don't see why it would be a problem.
I'd say ebb&flow would be the easiest and you could probably set it up for a single plant by the size of tray you use. For a single plant I'd probably go with a 4" rockwool cube and fill the tray with hydroton. There is a post here on RIU I think that explains the DIY Ebb&Flow set up.I'm thinking that I want to try a hydroponics set up. Whats easiest and most basic for a single plant and what are must haves and what are should haves?
I have this system and not real happy with the MH lamp, not really seeing any difference in growth compared to my cfl grows. . I also had a problem using the yo yo hangers, probably just me, so I switched to ratchet hangers. I've been growing with cfl's so I'm new to this and feeling my way through.
I'm using a 250w MH bulb that came with the system it just doesn't look like the plants are reacting any different than when I was using cfl's. I'm wondering if the bulb supplied with the kit is sub par and maybe this would be an upgrade. If you could point me to this $11 bulb I would appreciate it.you probably can't use them effectivly, I suggest spending the 11 dollars and getting a light off an ebay store
With the system I have ( http://www.ebay.ca/itm/250W-Digital-Ballast-HPS-MH-Grow-Light-System-/370622128347?pt=LH_DefaultDomain_0&hash=item564acce0db#ht_3775wt_1396 ) I will flower with the HPS bulb. As I stated above I'm thinking these bulbs supplied with the system are not that good. The aquarium lights have very high Kelvin rating.grazz go soil,i would like to see the results.
slotr1 yeah you can use those bulbs.not the greatest flowering bulb but it will work, good for veg and should keep the stretch down in early flower.

I am talking about light spectrum when I say kelvins. I thought they were important, that's what made me noticed the aquarium bulbs with with 15,000 and 20,000 kelvin rating compared to other MH bulbs with 4000 to 6500 kelvins.This isn't ebay but it'll work for you.

Kelvins are the spectrum of light production I believe, I'm thinking you mean Lumens or candle power in which case higher is better 99% of the time.
