Hi Guys, Just a quick question, how much heat should a balast generate? I'm just in the process of fitting out a new wardrobe and have begun heat/noise trials. My drobe is approx 500Dx1200Wx1600Hmm internal grow space, I have a 400w HPS in a cool tube being cooled by a 100mm inline. (I'm still not happy about this, the guy at my local store talked me out of centrifugal and into this, it seems ok at the moment but it is first on my upgrade list) So, for the trials I have just sat the balast on the floor, but I have notice it is generating some serious heat, is this normal? It isn't in the direct light and the box is maintaining a nice 27c about a foot above floor lev…

Heya Guys , well Summer is goin Bye -bye's and most are getting ready for their new grow....Woot Woot! But when was the last time ya ripped the duct off and had a good look at the fans internals and the carbon filters condition? Dust and Debri is a major contributor to electrical fires, once it builds up it blocks airflow and can cause over heating. Here's a shot of mine, was mounted in roof and the inlet from manhole in room, 200mm Centri, 250x500mm carbon Filter, so shouldn't be a lot of dust and stuff eh? Well Guess again...............6 months use after clean....... and this is what I found... As you can see on the carbon filter, the panels are choked with dust e…

Hello again everyone, I've purchased my new grow tent (2.8x1.4x2M) complete with 2 600Watt ballasts, globes and a 10" centrifugal fan. Would I be better off going hydroponic straight away? I kind of wanted to start in soil for my first attempt, but i am after maximum yield in minumum time. What would the difference be when growing Pure Kush? Thanks!

I recently went to the local hydro store and was interested in buying a 400w HPS and was looking at buying a metal halide that would work in the same reflector. The bloke there said that 'Using a metal halide during the growth stage was what all the old school growers do, but you can just use a HPS the whole way through, you just have to remember to change the light on hours.' Anyone else tried an entire grow using HPS start to finish, and did you see results just as good if not better than using a MH or a fluro?

The woman at my local hydro shop told me (after phoning the owner) that most of the current LED's are crap, but they are waiting for new digital (?) LED's from a US co. but prob won't arrive til after Christmas. Does anyone know a source of these 'new tech' LED's - she said she didn't know - (or maybe wanted me to wait and buy them locally?) Fair enuf but I would mind one now - my prob is limited grow space = excessive heat with hps or mh, plus with summer coming - a 90w=400w hps would be nice - but not from China... no offence. Anyone ...?

Hi all, I am wanteing everyones experience when it comes to using ozone for odor control. I know many of you swear by carbon filters and they are good, but in my particular circumstance I have a carbon filter in my tent (1.2x1.2x2) and another carbon filter with fan in the room the tent is in so the tent is pressure neg, and the room the tent is in is also pressure neg. So the air has to clear 2 filters (small and larger one) before being expelled out of a second floor window. The Carbon filters are 6 months old. I am still having some odor issues in the air being vented, on a still day (no breez) you can catch an odor when drying and from week 5 on wards. No I believ…

Hi all, I have a quick question with regards to carbon filter and fan cfm. I have a 6" 440cfm carbon filter and a friend gave me his 6" 192cfm fan and I was wondering if I can use these together? The space is only 4'x 3'x 5' so would these work together? Don't really want to spend the money on a new filter if it's not needed.... Cheers guys.

Would this work. I have an air con duct in my grow room ceiling, I was thinking of leading my exhaust duct into that vent and letting it blow into it. This would be good for spreading the heat around my house, but would it ruin my air conditioner ?
