Significant heat loss, that ballast gets hot!
Click to expand...
Ok cool thats what i thought... It gets hot, but i dont know how i would mount it any other way. This was i can just raise it easy, and i need the heat, the closest is pretty big... Would like to make a cool tube, but then i would need to get that heat out with a huge tube and i dont have space for that. I just have one little oscillating fan in there:) Im thinking about ordering another one, do you think it would be fine if i mounted it from the side? Or would that make the plants grow weird??

Take a look at the progression of my light, I didn't always use a cooltube, you can easily just remove the ballast, remote it, and attach the socket to your mounting point with a screw.

Some growers dont remote the ballast as they need the additional heat to keep the grow space within the correct temps range..But a remote ballast also helps you get the light position just right, as you tend (depending on HPS manufacturer) to get a lil more useable room with the ballast out of your cab, and it opens up new possibilities of where/how to mount the light.


What are you using for internal and external venting christian?
Even if your temps are good or atleast within close reach of the ideal, you should still be doing a complete air exchange in the closet every 5 mins.
An oscillating fan is perfect for keeping the plants cool and toughening up the stems etc, but you still need to provide adequate gas exchange in the area.
For example i have 1 x 12v fan (slightly larger than pc type fan) blowing over the plants and 2 x bathroom extractor fans with filters for internal and exhaust gas exchange.
Temps rarely move from 76-78*C

Plants always grow towards the light, Your plants will not be affected by fan positioning unless the fan is too strong and it forces the leaves to the side..
but they will look wind swept.

Thanks for the long advice bro. My closet is the only one i have in my apartment, is about 6ft X 9ft and about 4ft deep... Its pretty big, i have my plants on the floor in one of the corners... I think my temps vary quite a lot as it only will get warm in there if and when the lights are on...
The only venting i have is opening and closing the closet, i can turn the fan on... But as you said it would be optimum to have airflow every 5 mins... Its a pretty big closet so im not too worried about the air going in and out, it think its fine... but should i be more concerned? You seem to have good air flow... home many plants do you have? And how big of a grow room?

Sounds like you'll be fine bro..Poor ventilation can lead to probs with mold, so you could poss have a coupla probs with that, but its easily remedied.


My cab details are as below,and the post after that, although a couple of small changes have been made..ie added an extra 4" fan.
I currently have in the cab:-
1 x Lifesaver - flowering - 2.7 ft
1 x Magical grapefruit - just started flowering - 2.4 ft
1 x Sour diesel - showing pre-flowers - 14"
1 x Kerala krush - Showing pre-flowers - 16"
1 x NL#1 - just Showing pre-flowers - 13"
1 x Auto ECSD - 13"
Plus 5 x Grapefruit clones

ok, i know u know my 150 setup MM, but here's the skinny for anyone else interested.

PC hideaway storage cupboard - dimensions (H)128.3, (W)74.8, (D)53cm.
gutted it of the shelves etc, lined with reflective sheeting..
2 x 4" 12v fans for inlet with voltage adjuster so i can speed up/slow down the fans, fitted with home made filter from cooker extractor hood, running 24/7
Remote 150 hps ballast,150 son-t plus bulb, ceramic e40, dutch barn style reflector fixed to the roof of the cupboard,
4" bathroom extractor fan above the reflector to draw out the heat, and act as the exhaust, again homemade carbon filter on top...Not sure bout the CFM of the 4" fan.
I do also run a 65w Cfl in there just to even out the color spectrum a lil for the younger plants, seems to work out just fine too..
I only use organic soil and nutes as a rule, altho i am trying some tricks out using Dr hornbys big bud and bud blood, but thats in the other grow space...I dont like using synthetic nutes,but i thought i''d give it a whirl..
Temps are maintained around 73-77,

The whole setup is run 12/12, so yes i do go 12/12 from seed in there too.
And generally end up with 3ft plants with 2oz plus per plant.

The lights will be on soon, and i'll get some pics of the setup and the current UK cheese x sour diesel that i'm waiting to chop.
Its getting cramped in there at the moment while i wait for the chiesel to finish.

This setup works great for me, i tend to do my experiments with my autos in there but i often grow regular strains in there too and theyre happy as hell.

Hey everyone. Since I have a 150 hps I figured I'd finally post on this thread since I have something worth posting finally. (had 2 plants turn out male like a month ago . . . id dont wanna talk about it it was depressing). But here is my Grand Daddy Kush plant 2 weeks into flower grown under 150 hps the whole way.

Got an ionic carbon air filter and ventilation (2 way) in the room. but its a closet setup so not that big. Got the plant as a 2 week old baby from my friend and i've been growing it since.

And now what you all want: Pictures!

Hey has anyone ever grown Northern Bright (fem.) from Nirvana? I got the seeds for it but I haven't germed them yet. Just wondering if its worth it for my next grow or if I should try something else.

1st grow. Bag seed / Rockwool/ Gh nutes/. I veg for about a week then put them in 12/12 was scared of a height issue (growing in sunroom wit low roof) and i Diy a ebb& flow so i wasted alot of vertical space thinking of changing to a drip. Good thing is the light can stay about 5in from the plants wit no prob. Been flowering for almost 4 weeks. The smallest 1 is 1 week behind.
