High twisted Nibbz, Dugout here. My first question is do you have your ballast in your grow room? If you do this will also raise the temp in your grow room so if you do put it out of the grow room. I have been having the same trouble but not to the extent probably about 90 degrees. (they need to put a degree sign on the computer pad). I really like the idea Dr. Vandankenstine had I think that will solve my problem but with the heat you are talking about I don't know wether that would be enough for you. Thanks Dr. V I have been looking for a solution to this problem and I to cannot cut a hole anywhere do to landlord. Well Peace my brothers and burn one form me the Ole Hippy DUGOUT. PS there is a guy on indoor planting named Al B. Fucht that is very knowledgable about indoor growing so I take my questions to him. Had a problem with getting to many different ideas from other that it got really confusing so I just listen to one know don't get me wrong if I hear something that sounds like a good idea I run it passed him and he has never let me down. You might get a hold of him on here. Don't listen to everyone on here not all know what they are talking about but like to act like they do. Best to find one person you trust Peace and out

Yes matey i do have my ballast in my grow room.. Its a part of the light its a case with a ballast, reflector and bulb holder and a small fan to vent the heat from the ballast out the bottom. i would of taken it too bits a long time ago but with it being actually owned by my bro you can guarantee as soon as i take it to bits hes gonna say i want it back after that grow and ill be left trying to put it all back together which if your like me never works the way it came apart.

ive also found out that the emmisivity on my thermometer was waaaaaaaaaay out and now ive sorted it the temp never seems to go above 95 f and with winter arriving fast im hoping it will go even cooler... the degree sign is on the keyboard you press and hold alt and then tap 0,1,7,6, then let go of alt voila... °

thanks for the info about that guy too ill think to consult him on any problems i incurr...

You say you cant make holes in the wall, you really should consider it.

i wish i could...the only way round it which ive been considering is, saying to the landlord that now i have a baby i need somewere to dry the clothes she makes and so ive been using the airing cupboard for that, and its been getting really horrible and damp in there so i put a vent fan in the roof (similar to bathroom to vent the steam) to get rid of the excess damp in the air to the loft. I rekon he would be happy with that and that way i get a vent i can use instead of opening door all the time to let heat out and air in!

What ya think?

Its not that he comes around a lot its just the gas man does his checks regular and if ive got holes to cover up every 6 months or so the roof will start to look a right mess!

I hear you. I recently started in a grow tent in My garage. The heat from the lamp is unreal. i had to run a window ac unit in a window. get an inline cooled reflector. and have strong intake and outake fans. and im still gonna be pushin 95 on hot summer days. So i feel you.

Keep a small fan in the box or room to keep the air stirred.
If you can figure out some way to make a small air exit hole and hook up and inexpensive fan pushing air out.

its a pain in the ass innit! ive got a 6" fan blowing from back to front across the lamp in between the plant and the bulb towards the top of the door where when i vent it blows all the hot air away and its always moving inside the closet.

"I believe the lamp fitting is designed for 125, 250, 400 n 600 so shudnt be a prob..."

wait man, the fitting or the ballast? Most grow bulbs fit into the same fitting, the ballast is the big transformer-looking box, that's the important bit. You have a ballast that switches between wattage? I didn't know those existed...do you have to switch it or does it do it automatically? What brand is it, where did you [or your brother] get it from, and how much did you pay?

Usually ballasts are designed for one wattage only. I dont know anyone or anywhere that sells a ballast that can be used with bulbs of different wattage. Nitrobud is right on, use the wrong bulb and you're asking for serious trouble. Find out for sure what your ballast is [Im guessing 600w] or you're gonna keep melting things.

gd luck with your extraction troubles,

ps
MH bulbs are a lot hotter than hps. If you're growing one, or even a few plants a 250w hps is plenty, and will definitely be cooler than the 400 or the equivalent mh.

I did the double check on it and its actually a 400watt ballast so ive put my new son-t bulb in it again and left it be as it is. Ive been of on paternity leave and the room seems to be steady between 80°f at the very bottom of the room and about 95 - 100°f at the top just under the light( quite a distance at the mo) with the fan blowing across the light towards the crack in the door everything seems to be ok for now long as the curtains stay closed which for the sake of a few oz if it turns out right is well worth it. ive also planted just the one seed to see how it comes on and see what sort of result i get now instead of germinating a few and wasting them... upto now ive seen a massive improvement and the seedling now has two sets of leaves with a 3rd rapidly emerging from down between the 2nd set. the leaves are a lovely colour and ive used a container about 5 times the size of the old one to plant this plant in and hopefully make it a bit stronger more room for a bigger root system as i think the last pot was also a bit small.

The seed is northern lights and all the seeds ive germinated so far have grown and been female about 6 i think.

now ive just been told i am allowed to have my girlfriends parents greenhouse because they are re-designing the garden is it worth it or am i better off sticking indoors in the closet with a roof vent?

also thanks for all your help guys... just need somewhere to upload the fotos too and ill show ya the new one as she sits now and the room im talking about also.

Right then guys bit of dilema for ya!

Ive been growing on my window cill for a while got a plant to a really nice size and then my brother decided to give me his 600watt HPS grow light. Ive downsized the bulb for a 400 watt son-t bulb due to room size and added a fan for circulation, however... After leaving for work for the day i returned to a 8 inch melted mess! It was completely (excuse my language) FU*KED.

Now i live in rented accom so i cant really go on and drill holes everywhere... The closet its in is the perfect size if i can get it cool enough, its an airin cupboard approx 2.5 ft x 3 ft x 6 ft tall, it is fairly warm anyway and its on the top floor, in my bedroom, so i cant just leave the door open in the day cuz ppl will see it from outside and i cant leave it open at night for the same reason it will keep me awake. I cant run pipes to the windows or doors because if the landlord comes in he will see em and also my girlfriend will throw her toys out the pram cuz of the mess lol.

Now my problem is how do i get the temp down and keep it down? without shelling out too much money str8 up.

I bought a digital thermometer and its pushin well past 120 f, now any thick fool would realise thats ten times too much i just cant figure out a way to cool it down enough to keep it reasonable to grow a plant. If i cant suss it out ill have to revert to window growing but as you will know its startin to get cold out, and so not a lot of sunshine comes in my room (wrong side of the building) so is there anything i can do?

any help will be used wisely thanks guys and i look forward to your replies.

You should not be using a 400 watt bulb with a 600 watt ballast you will burn your bulb out too fast and could cause a fire, i have the problem of cooling my room down also i need to cool it by 5 degrees C the only way i could really is to leave the door open but then i get the sound of the fan all night so....
