My company retrofits leds in overhead lighting in offices, laboratories. I have experimented with 4 @ 18w led tubes, but that was not enough wattage. I am ordering some new tubes @ 28w. 6+ of them in either horizontal or vertical should work well for a small grow

I need a lot more wattage than that I think! Probably 20 or 30 of them per rig!

I think your set-up still calls for HID atm.... their really isn't anything on the led market that i know of that would replace a 600w vert bare bulb. Buy a summer set-up of mag 400w MH ballasts and 330w allstarts CMH bulbs which should do a "nice " job at half the wattage, make your cooling requirements easier.

Overpriced chinese junk by a scam artist who likes to call the cops on you when you have a consumer dispute............stay the fuck away from that company!!!!!!

Lol very usefull info. What a bastard hey!

I'm currently fine with x2 600 HIDs and will be during summer with a better fan if I leave things as they are but I'm planning on putting x2 600 HIDs in each rig though hence the need for some serious air cooling and possibly an air con. I've also got a tent with an enviro 250 and another small tent with an enviro 200 with x2 cheap LED light boards. The 200 in the small tent only clicks on 15 minutes every hour though to supplement the shitty LEDs cos it's just for mothers.

How many BTU's needed to control a 3kw grow u reckon if the x4 600 HIDs are vented via cool tubes straight out the room. I'd need enough to control the 450 worth of fluorescent and 4 hot ballasts and summer temps and any residual heat that the cool tubes don't get out of the room. I'll be using a 10" airforce fan so serious venting for a relatively small room 4m x 3m roughly.

The trouble I have is some of the vented heat back fills into my house cos I vent from the grow into the kitchen and it finds it's own way out the kitchen ventilation point for the cooker. I close the kitchen door and I've sealed it with this draft excluder stuff but I can't seal up the bottom of the door so it gets in through there. I'm only currently using a 6" fan as well.

is there anything wrong with using air conditioners in rooms that are vented or does the room have to be sealed for the air con to be effected. I mean sealed other than the exhuast from the air con.
