400w Club-Show Off Your 400w Pride And Joy

You can hit 1gram per watt no matter what light you are growing with if you have the skill. Hitting that 1gram per watt mark is a bitch to get there, and not many actually make it. I have been sitting at like 1/2-2/3 a gram per watt for the past year or so.

I am going to be sealing my room and running Co2 at 1500ppm consistantly next time, so I am hoping to get a little closer to that mark. I think that Co2 and experience are the ways to hit that 1g mark. Co2 will not be the "cure all", but if you have the experience, and have been hitting like 2/3 a gram per watt without it, I think that would be the best way to make it there.

I was running a 400watt ballast kit from HTG for quite a while with just a home depot HPS bulb. I have since switched to a 600watt ballast kit from HTG and actually bought a horticulture bulb. Going from 400watts to 600watts, my yeild nearly doubled.

Jonask, Beautiful buds man. Can you tell me a little about your room set-up ??? I have a very small closet that I want to use that looks REAL close to your grow room in size, also, do you just have one 400w in the room ?? How many fans are required ?? Charcoal filters, etc.??? Sorry and thanks for any info.

nice jonask! i also had a couple of questions about your room. I see you have a screen up blocking the door way. I am assuming this is to keep peices of airborne fibers from getting into the area. I was wondering where you got somthing like that. And does the air pass through it well? Also i see the fans that you have hangng. I was wondering how you have those hung and which way they are blowing? Are they pushing the air up or are they pulling it down. Also what is the temp and is it constant? thanks for your time and keep it up!
 
Question for you guys:
18sq ft closet, with an ac vent in the closet and a fan, currently have a 150w HPS and have no heat problems, will it work if I move up to 400w HPS? Using a waterfarm for one plant two weeks into flowering but have two 18" plants I need to put in there so need more light.....

the screen it was only to prevent my cat to chew my plant leafs (she 'the cat' loves it, actually she grow crazy with weed ehehe) the airflow was like if there were no screen didn't see differences, the fans at the beginning are blowing air sideways on the plants top, later on when the plants are big enough i put them hanged down blowing down, usually the room temp was around 27ºC in day 23ºC by night but without the big spinning fan it can esaly reach 30º/31ºC and I didn't use C02 this crop was grow in soil in a 5,5 liters pots and the plants reached in lenght about 130cm.

:peace:
 
Thank you very much jonask! If i was your cat I'd be hanging out in there too. I would have to say that this is prob the nicest job i have ever seen in a space like this. I have a very similar setup and im am running into heat issues. i cant get the temp to drop below 82F.
 
82degrees is not bad. I run around that all the time in summer, and still get killer buds. If you are up around 90 or if the plants are showing heat stress is when you need to watch out. If you have no heat stress, you shouldn't have any problems, just be careful about your nute dose. You just need to run a little lower dose to make sure you are not going to burn the plants since they use more water when its hot.
