250w HPS users....

[TheOneWill]

What would go best with these dimensions. I got a 400watt hps laying around and wanna see if it will work in the size of cab if not I'm gonna have to get a 250.
2 ft deep 3 feet wide and 3 1/2 feet tall. I plan on using a cool tube.

Deft, CMH bulbs do not work with digital/e-ballasts.

After looking at lumatek's specs (http://www.lumatek.co.uk/Products.htm), it looks like their ballast do indeed work with metal halide bulbs. I've also heard that lumatek ballasts are pretty good on EM noise as well.

Common MH bulbs and ceramic MH bulbs are quite a bit different. For whatever reason ceramic bulbs are not compatible with e/digi-ballasts. The CMH bulbs that most of us are after are actually HPS retrofits so they work on HPS ballasts. Believe me, if CMH bulbs ran on e/digi-ballasts I'd probably have a grow log ready for you guys to check out by now as I am a supporter of those type of ballasts.

So if anyone could recommend a quiet/silent 250w mag ballast, by all means...

In the CMH thread simba said that noisy magneto ballasts are just hot, at least thats what he said. He talked about sticking on heat sinks for computer use to solve that lol.

Hey Deft, It works that way with my balast too!

8bit, lemme just throw this out there: a lot (most?) of the people who grow under 250 watt lights are doing so either because they want to do a small grow cheaply, or because it's all they have available to them given the idiot legal issues. As such, a lot of 250 growers don't go out and buy a particular ballast and lamp and reflector. Instead, they use what's either cheap or around.

As an example, I have been growing under a 250 watt HPS light I bought from insidesun.com. Does it work? Yeah. Does it work particularly well? I dunno, probably not better than any other system. It's hard for me to recommend it to you because it's not amazing, and it's not fancy, it was just cheap and available.

I know I'm not answering your question directly (again), but I'm hoping someone will answer to tell me how wrong I am and say what ballast they like to use. Otherwise, the answer you're likely to hear is 'find something and make it work.' Folks who do choose a specific ballast and buy that one are probably buying digital equipment. I would say that if you want a good magnetic HPS ballast, find a company who makes quality ballasts in general and then buy their 250 watt model.

These plants are growin under 270 watts of light, took these pics last night

This is DP Blueberry, it's really starting to develop a sweet smell, but really skunky




I'm not exactly sure about the origins of this strain but due to the description of the guy that sent me these beans I believe it is Soma's NYCD x Cotton Candy crossed with S.A.G.E., smelling this really tickles my nose when smelling too long, reminds me of lemons and something just really spicy.




End of 7th week.

[THC•20]

250W harvest!

God damn, I need some help from some of you heavy yielders of the 250. I need to get the most out of my plants as possible lol. I want at least 6 oz a grow, I grow 3 plants at a time. It'd be even nicer if I could pull 3 oz/plant with 270 watts lololol.

 

[guest101]

Sog it mate! 9 smaller plants... to 16.
Scrooging and LSTing tends to make less harder and a bit more leafy buds.
Aparently, whats more, results in less... quality that is!
Keep it green!

 

[Deft]

Yea I intend to get a SOG going, trouble is I need to grow some moms first lol, but I have a good bubbleberry female and just took a clone of a biddy early female and have two biddy early seedlings vegging away.. I need to go check out all the dumpsters at local nurserys and find some adequate large square pots, I used to work at one and used to throw out dozens and dozens of pots from plants that died before being sold... wish I had kept some of the good ones lol.

I just bought my 250hps for $109.60, bulb ballast reflector and housing, its a security light but will be fine once I set up a good reflector and wire the ballast remotely.

Does anyone know where you can get mylar from a common chain store?
