from the limited information i have found so far on the forums, the CMH 400W is better than MH for veg, and HPS for flower. It emits a spectrum much closer than either do, yes the other lamps peak higher in one or two area's but the CMH is my option for both cycles, unless I can fit a 1000W HPS...

Ok, I took a soil sample from both of them, in an hour or so when i get the results i will post them, thanks for the info so far!

Ok so here is my room, its a 2x4x7 (Pic below). I just got myself a 30inch Cooltube for 2 bulbs. Currently I am using a 400W CMH, my option for the second bulb is a 1000W HPS, or another 400W CMH. The purpose of getting the 2 bulb cool tube is to remove my 432W T5 side light. I love full...

Hey These are two of my babies that are having a hard time adjusting i guess, Where the tops of the plants are at is right around 73F-75F during lights on, 62F-68F during lights off. I have fed them ONCE with 1tbsp of molasses per gallon of water, then about 5 showed signs of over watering, so...

Nevermind, I just found out that It will be 8,000 Lumens per sq ft with two, and half that with one, since the sun is 10,000 I guess it literally would produce twice as much. Thanks for those of you that at least viewed this thread, sorry for the repeat question!

So where do the 400W CMH lights stand? I skimmed the last 19 pages and did not see anything, but maybe I missed it.

Well I am using a CMH 400W, and I was debating getting the 30 inch cool tube to fit both in, but I am only working with a 2x4x7 room, my question is, how much % yield gain could I expect on my grow? If the finished bud amount would be dramatic, I guess I will go ahead and buy this cool tube, and...

A plug and play unit like.... what? Thanks for the input!

So I have a 2x4x7 Room with an AC intake on the floor and an Exhaust in the roof, my problem is that my temperature drops VERY low during the night. I have heard that you do not want more than a 15 degree change as to not stress the plants. The AC is controlled by one control in a separate part...

thanks Thats what I wanted to hear!!!!

Well I felt like making a post so here is the worst case out of 8.

lol funny you mention that, I spoke with riddleme the other week, and I use his technique of "Making it rain" I think i just need to let them dry out more in the sink before i throw them back in the room, for my next watering. It's a real pain dealing with soil in a hardwood floor closet >_< I...

lol I tried one of those outdoors, and i HATE them! I guess im going to get the PH, N, P, K kit tomorrow :P the PH is just under 7 by the way, across the board

I know they are small, but I dont think they will get that tall, this is a pic of one of the healthier ones

thanks for the input! I watered them with plane jane today, and i might do it tomorrow as well, as a flush.... Or should I wait until the next time they need water? It could be nute burn, since molasses is the shizz!

Bump! I need help I want them to be healthy! I really know next to nothing about pre bagged soil and I am thinking I went wrong there.

I am using a 400W CMH in a cooltube 6inch hooked up to a 320cfm exhaust for a 2x4x7 room. I have a 8bulb T5 on the side and a 4 bulb t5 on the other side (4ft, 6/6 6500k/3000k). An oscillation fan is also going at the pants growth level, pulling air from the AC vent I put in the floor. 1048W...

I am using Fox farms Light warrior on my Jilly Bean seedlings that are just under two weeks old. I watered with 1tsp of Molasses in my one gallon pitcher. I had little trays that went under the pots but they retained too much water (they were left like that less than 5 minutes) They were seeded...

I have 8 Jilly bean seeds (non feminized) sitting in the dark cycle at day 7, call me crazy but I have been reading a bunch of BAD reviews on Jilly Bean, as far as end product. I have 1 White Russian seed that is fem from serious seeds. Would I be better off Vegging the White Russian to hell...

It is from seed, but I also have Utopia haze coming up next. I do believe it was adapted indoors for 3 years? Basically it depends on the strain then? The more it is grown indoors the less root system it develops?
