A free seed I received from Nirvana. Just don't know what it is. Smokes, tastes and smells great, flowered for around 70 days or so If I remember right

can you use CMH in a electronic ballast? and is it much different from MH?

Well technically the answer is: NO, like wyteberrywidow said, however there are digital/electronic ballasts that are specifically designed to fire CMH bulbs. This is the best site Ive found for CMH bulbs: (---->CLICK HERE<----) They are the Philips MasterColor CMH HPS-Retro White which are supposedly the best on the market for growing and there the only company that Pre-Burns there lamps, why pre-burn, because they have a very high initial failure rate so when you buy from these guys your guaranteed a 100% operational bulb. As for the difference between CMH & MH, well I'm no expert but like wyteberrywidow said standard metal halides produce light mostly in the blue and white spectrum making them great for vegetative growth, the CMH on the other hand produces a much fuller spectrum, some say its the closest artificial light to summer sun you can get indoors, check out the Philips CMH spectrum compared to HPS:

And here is a Philips MasterColor CMH compared to a GE CMH (Not all CMH's are equal):


I'm building a closet grow box approx 4'x5'x3' and I have a 6" air cooled hood and 400W ballast and I will ABSOLUTELY be using a Philips MasterColor CMH, can't start anything until some electrical work is done but I can't wait to get started .

Pure organic Northern Light cycle. With Topping and Lolipopping techniques used.

Thought I would give an update on my grow. Its been about 3 weeks since last post. Looking really good. It looks like i've got about another 2 weeks.

So your only using one 400W HPS and no other supplemental lighting? If so that's some pretty good results, I imagine you have a air-cooled hood w/ducting etc., what size inline are you using? Is it a passive system, where is your intake and from where do you get your fresh air ie: Air conditioner, window/outside, floor/wall vent, surroundings/room? Sorry for all the questions as I'm new to this and this will be my 3rd attempt at growing (First two failed from lack of experience, equipment and proper setup) so I want to make sure I do things right this time. I'm going to build a grow box out of 2x2's that's approx. 4'x5'x3', I'll be using a 6" air cooled hood with a 400W Philips MasterColor CMH on one end and a 250W HPS on the other end and if I can get the funds together I'm even thinking of putting one of these on both sides of my hood (length wise), one with a RED bulb & one with a BLUE bulb, Check out this BAD BOY: (---->THE BEAST<----)

The point behind this is that not only will it produce excellent results, I won't have to make any physical changes to my lighting through out the entire grow, one setup does it all, this seems like the perfect setup for me but what do you experienced Master Growers think?

Yes there a few dollars cheaper from that site, however they don't Pre-Burn them first so its a shot in the dark weather you'll get a working bulb. Read my post #4802 (10 Posts Back) and you'll see why Pre-Buring is important.

im in also now lolView attachment 2016909250 to 600 now a 400 lol

curious as to why you went down from 600 to 400? I just got my 600 today but im still going to use my 400 hps.. I love that light plus it was my first purchase ever indoors..Im happy with the results i got from it..So ill be running both for flower in seperate tents. 1x 600 tent , 1 x 400 tent and maybe ill get a 250 to veg dont know yet..

that high failure rate stuff is hype to get ya to buy it from him...the owner of advanced tech lighting is Simba on the icmag thread...I have been using it from that company for years...just purchased 4 400 watt hor and 1 400 watt ver and they all tested fine...not to mention the prior five which are all still working within lumen parameters...there is misinformation on the icmag thread...major one is the uvb claim...it does NOT produce any useful amount of uvb if it produces any at all...jus saying

 

[Shane1661]

I'm putting a 400w Dual Spec in a cooltube, into this cab when I can afford one: opinions lol

View attachment 2020462

It's 90cm wide x 80cm high x 40cm deep though I'm sectioning off the small right hand bit for extraction and storage.
so minus about 25cm from the 90cm

I've used a 400w before and had amazing results in a relatively small space, had to go to CFL's and LED's for stealth/lack of space and money, now I've developed this cab for my next grow.

What do you guys think?

Any advice on using a 400 watter

Happy Growing!

That box is a little small to house a 400. 3 feet wide x 1 foot deep and less then 3 feet tall? if you dimensions in cm's is correct then that is too small for a 400.

That's what I first thought, but looking at some other grows in smaller cabs with 400w hid's than this is what inspired me to try this.

I do have a pretty powerful exhaust fan too XD
