250w HPS Club And Help Guide

oh yeah im waiting for any of the stores in my town to get some soil. you can tell its outdoor season. people buying all the bags.
 
i think it doesn't matter white to white or black to white..... it'll work ether way , that green wire is for ur protection , electricity wont hit u if it has a way to go in to the ground , it will not damage any equipment in case something goes wrong cuz the excess electricity will go in to the ground.... like someone said before , if u connect the green wire to ur reflector and in some way wires come in contact with the metal hood on the reflector and u touch it , u wont get hurt... cuz the electricity from the white or black wire will not go in to ur body but in to green wire and safely to the ground, if u don't have proper grounded plug/socket in ur house , this will not work... and i dont know about ur country but most public housing buildings in my country do not have that , they connect grounding wire to the 0 wire with a plug , no third wire... that may or may not be the case with ur house /apartment
 
Just popped a couple seeds a few days back. They are my Mystical Mutant which turned out to be very awesome.. nice berry, fruity smell and a social to couchlock buzz and so far the best medicine I've had for my thoracic/cervical pain. Since I didn't keep any clones one of these will be kept as a mother. The other pics are the clones I kept under a single 100 watt (26 real watts) CFL for about 10 weeks while waiting for the BM/MM grow to finish up. Looks like I'm going to have another midget grow since they haven't stretched much at all since putting them in flower about 4 weeks ago.

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.

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.

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.

Correct! I hacked it up with a dremel lol but I reused the wiring and socket.
 
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'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.
Must haves:
Tray (I used a Plastic Cement tray from HD)
Fittings (available online)
Hose
Pump (Harbor Freight)
Timer
Resiovour <sp> (rubbermaid tub, fit to your area.. I use a 20 gal but only fill it with 10 gals)
and all the other stuff you already use to grow.

BTW: I'm thinking of trying soil..lol
 
Maybe someone here can answer my question. I'm new to using metal halide lamps and would like to know if MH bulbs that say aquarium lighting are usable as grow lighting? They seem to be rated much higher in kelvin units than grow bulbs and I am not sure if they are usable with my 250w system. Any help is appreciated. Thank You
 
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.

you probably can't use them effectivly, I suggest spending the 11 dollars and getting a light off an ebay store

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.

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.:confused:
Thanks for all your help guys.

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.

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.

Yeah bro, my 250 came with MH and HPS bulbs. I never bothered to use the MH, but the HPS "seemed" to do great, I've gotten some nice smoke off that bulb.
However, i recently spent $12 on a GE Lucalox bulb. All I can say is holy shit. I grow 12/12 from seed, and one of my plants is nearing the end. About a week after I started with the Lucalox, the bud just grew gargantuan. It's probably gained an extra 40% mass in the last week and a half.

Nowadays, you really don't even NEED to run a MH for veg anyway.

Here's what i bought, it's 2100k

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.
The bulb I am using is rated 4000k and 25,000 lumens. Maybe I'm expecting more than I should with the MH and HP setup after using cfl's all these years. Thanks for the link, I have purchased many a cfl from them.
