I have read a few old threads about members trying to find cool tubes for HID. I know that they are now freely available, but was wondering what sort of temperature drops you guys were experiencing now that you have used them for a while. I was quoted $130 for the 150mm diameter for a 600 watt, and I have to purchase the ducting and the fan on top of that. Any info much appreciated. Regards aussie1

Hey guys I need some ideas ,, I got a room 3x3x2 mtr ,, its only source of of ventilation is 2 x 100ml x 4mtr long pvc pipes , the pipes run straight up ,, the room has aircon and only 2 x 400watts ( clones and mum) . Now I want to have a carbon filter on the intake to catch insects and mold spores in the air . What size fan ? what size filter ? remember it must pull the air 4mtrs down a 100ml tube and through the filter , I was thinking a 150ml fantech but not sure , what do you guys think . Thanks Rod

Hi all, Getting to the pointy end of buying my centrifugal fan. Going with a Fantech 150mm centrifugal. Problem is no-one appears to want to sell me one..or at least you'd think so. hydro-aqua-pet.com.au have the best price by far $222 +shipping. However, I've found their service is an absolute joke. Days waiting for email replies. Even sent them a flame email over 2 days ago...still no reply. Gooses. Doesn't exactly instill any confidence. All other vendors I've contacted are $280+ plus shipping, so they're out of the loop at the moment. Can anyone recommend or point me to any vendor that 1. Stocks, or can source the Fantech 2. Has simple professional servic…

Gday guys I took this pic the other day with the lights off. I noticed that the center of the plant seems to be a little lighter than the rest. My lights are never closer than 10/12 inches. Could this stilll be caused by the heat? Cheers

Hello all, Would really appreciate some input on what fan I should buy. I've done lots of research and have narrowed it down to 2. Now deciding which one. A bit of info - growroom is 1.5m3, 400w HPS, 3 x 100mm passive intakes. Currently have 200mm bathroom fan as exhaust. I've recently bought a Phat carbon filter -150mm, and now just need to get the centrifugal fan. Here's a pic of the 2 fans. Both are similarly priced, so that is not a factor. Any input would be greatly appreciated. Thanks.

Hey all. I'm running 4 Lucragrow HPS in my flower room. My buds are really fluffy. When I compare them with a friend who has the same strain, hers are more solid. She uses no PGR's. I'm using Advanced nutes and she's using Dutchmaster. The only thing i can think of that may do it is she has HPS and M.H lamps in her flower room. Anyone who has used only HPS on it's own then tried adding M.H care to comment on thier findings?

Hi again stoners, It's going to get very hot here soon... I'm buying a cool tube from hydromasta.com, for $110 (ouch - a little too pricey, but they're discreet & friendly gougers, which is worth the xtra cash i guess). My set up is vertical, using 400 hps, room size is 3' x 3' x 6'. I was wondering if anyone has any practical experience & suggestions for the best fan size & type to hook up to it. Preferred brands? Suppliers? I'm thinking that I will hook the ducting & fan to the top of the cooltube & use this as room exhaust too, with another fan directly below the light to blow air up. Is this a feasible plan? I really have no idea at all - …
