About to buy more lights and was thinking of getting one of the new LED grow light and try it out. is there any buddy who has used them. I have a limited power in the grow room and if it works I would be able to have more light and not have to get some one to rewire the Box. All so I would save on AC in the summer. Right now it is winter and It is nice to have the space heater of a self balisted light. Any imput would be nice

I want to know Which of these bulbs is the best suited purely for the vegetative state. I know the blue spectrum is surposed to be better than warm for vegging but the blue delux puts out less lumens than the warm delux. Which is more important lumens or spectrum? Sunmaster recommends blue for vegging and warm for allround use but because of the lumen diference I'm still confused as to which one to use. My hydro shop sold me the warm, saying they were better. Heres a couple of links to the globes. http://www.hydroponics.com/hydroshops/usa_.../growlamps.html http://www.venturelighting.com.au/ heaps of info here but doesn't definitively answer my question. Heres…

I'm thinking of hooking up some ducting to a small wall vent to outside. It's an old plaster vent about 0.25mx0.15m, the problem is about half the area is covered by plaster so I need a fan with enough power to vent a 2mx2mx1.5m tent with 600w hps during summer with 20-35 average outside temp. I'll use a cooltube so it won't need to go thru a filter first and i'll turn off lights during the day. The house is a rental so i can't put holes in the wall but it's an old house so a bit of damage is ok if it can be painted over. I also need a way to attach the ducting to the wall and it's 3m off the ground thanks for any advice.

Is anyone using the larger twin lamp cooltubes? as any info or recomendations would be excellent! Seeming the hotter weather will be on it's way soon and I was going to get another 150mm fan I thought I might as well look into cooltubes! I am looking at the 150 x 900 twin lamp cool tube similar to these http://www.hollandforge.com.au/index1.html...103802088541596 http://www.growroom.com.au/p316/shade-cool-tube-900m-x-150mm Do I go for 2 x smaller tubes for ease of globe changes or the larger 900 twin? Cheers Canaman

hey all, I'll soon be planting my seeds for my first grow and was just wondering should I have the lights on 24/0 before the plants emerge from the ground, or wait until I can see the stem? high_hoper

So tonight i turned the light on but thought "hang on ill quickly get some snaps for the diary", it was turned on for 5-10 seconds max! was still dim, hadnt even warmed up so i unplugged it thinking it would be ok. Now when i try to plug it back in the light doesn't work and the ballast just keeps making a ticking sound. Does anyone know what could be wrong? I'm 2 weeks in flowering and can't afford a new ballast at the moment. Cheers

Recently i have been snooping around the ballast market comparing prices and reading propaganda in the hopes of coming to a definite conclusion. so i thort it would be fitting to post the questions i cant find answers to here. Does a digital ballast run significantly cooler compared to the standard ballasts ? Do the digital ballasts work with all bulbs ? yes i know it can be used for a MH or HPS due to microprocessors, im referring to the bulbs life span and start up strike. ( cheap ones vs expensive ones) Currently im using fluros but i want to get myself a MH and an HPS and when i heard that a digital ballast can run both bulbs i thort well heres a winner.......til…

I opened the room tonight and was shocked to find of my 600W globes had developed a strobe effect! I am just a little confused as the globe is new and hasn't been mishandled or damaged in any way. Has anyone else had this type of problem, do I just put it down to a dodgy globe?? Anyhow of to change it now Cheers Canaman

Hi everybody.....Ok ive grown sucessfully under floros an HPS as they both have there advantages an disadvantages. I want to try a combination of both, the HPS lights i want to use are a lower wattage than the ones sold in your hydro shops about 50 to 80 watts with 45 watt compact florescent lights arround the sides havent decided on the number of bulbs yet. My problem is i cant seem to locate a HPS light at such a low wattage. In the USA or even Europe you can pick up 50 to 80 watt security lights with HPS bulbs in them ive had a brouse at Bunings threw there lighting section an didnt see anything all there security lighting seems to be halogen i didnt ask anyone there t…
