Thanks

Are you running the cmh or are you interested in it? Just got 4 in myself. Loving it!

I have 315W Sun Systems for my grows.
Love it in my 3x3 tent.
Got 19.6 ozs last grow in soil.

I read your grow the other day and it convinced me that I made the right decision on my lights. I went with the Double ended 630 cmhs in a 10x10. Sample running 3 plants 2 strains under one light for right now.

Hey dudes, I started a thread while i was toasted a while back, "calling all CMH + COCO growers!" Lol..........I think it still exists:headbang:in the coco growers section....I only have one CMH in an 80 x 80 x 160cm tent and I love it dude, I have just put one ufo led in there to help a little gal who is struggling in the corner, think I will keep it in tho:pass:
 
Hey chums,

I use the retro fit 860w Phillips CDM globes in a GrowLite OG vertical cooled hood on an old 1000w MH ballast.

Interesting results, definitely a great light but I got massive stretch in preflower. Next time will need to train heavily to save on vertical space,
I didn't get a final result this grow due to my grow security being compromised, had to pull early.

Hey @fettled6 ...that fuckin sucks mate:fire:people fuckin with your grow dude....just curious what strain it was that stretched dude?:pass:

P.s ....I have heard that running CMH lamps on a HID ballast is a big NO NO, different wavelengths I think(?) apologies in advance if you know your stuff and i am wrong dude, just trying to keep us all safe dude:eyebrows::d5::woohoo:

The retro fits can run on magnetic square wave mag ballasts

The plants were 55days old and 5ft tall

4 different strains, need to employ more vigorous training and trimming than I am used to to keep them under control!
