hey guys, I don't run a CMH YET, but I was talking with the owner of Maryland Hydroponics yesterday and he guarantees that their digital ballasts WILL run 400w CMH bulbs! It is their own brand so they have it made to THEIR specifications. I also trust the owner, always makes good on their store...

Ohhhh! I did not know that. I have some T5HO single tube fluorescent bulbs coming so I will def mount them on the sides. Thanks guys, after a day of TRUE darkness the smell just SKYROCKETED! They are def going into full flower. Again thanks! Oh and I have a secret jardin grow room, but i just...

Nope, my mistake, you guys were right, pinhole leaks all over the place! Duct Taped the whole thing and placed a dark cloth over it. Also shielded the vents from light... Will that revert them to bud growth?

Nope, just turned off the lights and went in side, even at this time of day, no light leaks.... but I will get something to throw over it just in case

Naw I think I have that covered, it's a darkroom and that pretty light tight... but maybe a black sheet over it couldn't hurt...

Hey guys, could you guys help me figure this out... my plants just arent forming true buds/colas and it's the 5th week of flower! They have plenty of hairs but nothing else. Stats: 600w HPS 200W CFL, + 150w florescent sub canopy lighting 5-gallon pots with coco-coir Fox Farm line fertilizers...

Hey guys. I'm having issues with stretching, so I want to try some subcanopy lighting. My one question is this, since I'm running a 600w hortilux as the primary light (4th week of flower), should the subcanopy light be blue or red. I know blue makes for more compact plants in veg but I know red...

good to know! thanks man!

I'm reading 81F during the day and my place it set to 70 at night. I thought that would bee too large a temp differential so I used a heater to keep it at 77+- at night. Is this ok? Should I remove the heater at night and just let the temp drop? My light is air cooled and there is no way to add...

cooler at night? I read the larger the temp difference the more the stretch... huh... could have been dead wrong though. Anyone's take?

Ok guys, I made another post in the marijuana problems forum... namely because I forgot I had this thread. Anyway, here is how they are doing: 4th week of flowering. I had to cut off most side branches, there was no way they could support colas and they prevented light from reaching lower...

My babies are in their 4th week of flowering and t took them 3 weeks just to grow pistols/hairs. the inter-nodal length is getting way too long. I have them under a 600w, HPS with supplementary 200w Blue horticultural CFL. I thought that would help stop stretching. Any ideas?! I have...

that depends on what you mean by 'better.' I don't know any HPS bulbs that produce truly white light, only amber. But blue/white light is best for veg, amber/red for flowering.

600w in that small an area? damn, that seems like overkill... your going to need to air cool the bulb. A 400w would be a bit much let alone a 600w. The infrared is going to be too high to compensate for without an air cooled fixture and a glass lens. Even then, keep the surrounding area cool.

your best bet is to transplant them into some good soil in larger containers. This has happened to me in the past and that usually fixes it. Just make sure not to use MG soil this time. They do have an organic version at Home Depot but the chicken guano in it gave me a nasty bronchial infection...

There are plenty of us faggots who love the ganja and know our shit... you make a good point, try not to sound like a jackass while stating it.

I have heard of people doing that, but only for 24 hours, not 36. I have heard of using the 36 of darkness at the END of flowering to stress them into resin production. But hermies may result...

thanks :) they are my babies...:hump:

it's 600w on a lumatech digital ballast, should be enough and it's like jesus walked into the room when I open it. So I think I'm set with lights. I also did a bit of research as well. I used Bushmaster, which is cytokine based. It's effects have been a bit more powerful than expected so I...

I know I should have waited for pre-flowers to show but I was a bit impatient. They are from female seeds though, same as my last grow and they were %100 female. I'm not worried about the sex, but I put them in flower when they were small because I wanted to keep them from becoming monsters...
