hey guys just wondering what is the rule of thumb for applying LED lights to a grow tent? do you go by the amount of watts the light uses per square foot? go by the output watts the light is rated to per square foot? or do u just say fuck it and put as much LED light as possible in there? im considering puting 3-4x 300watters in the 4x4 tent, yes i will be using more power than a 600w HPS but thats not my goal to acheive, my goal is to lower the heat over this summer at lease in the veg stage and may consider the LED's for flowering

http://www.ebay.com.au/itm/151392468030?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 I found this Chinese copy of the Avenger Ajusta Wing/Shade on Ebay. I confirmed it was a copy as I rang the guy in Victoria. As you can see $75 is a lot cheaper than the usual price of around $200 for the large sized Avenger or even the large Defender which is around $150. Anyone purchase a copy of either one and if so how was your experience with the copy? If not can anyone see the dangers of buying a Chinese made copy?

Yes I know there shit house fans but I have had these since my first indoor grow attempt.didnt want to spend a shitload on my first try.since then I moved outdoors as I'm out bush and there's no better condition then outside in summer.I have 2 8" growlush fans setup in my 1.2 x 1.2 2m high tent.they are fine during the day but just alittle on the noisey side at night so I'm thinking of grabbing a smscom dual fan speed controller.I've heard crap fans let out a humming noise so I take it the growlush fans will.how loud is the humming compared to full speed on a 8" growlush fan.dont really want to hand over thatmsuch money for a temp control unit if the humming is as loud as…

hey guys, i have a question for the tent growers in here. im looking to head inside with a 3x1.5x2m tent. the plan is to run 4x600w in there. i would like to hear from anyone who has this kind of setup as to whether i could get away with running the filter/exhaust fan to run straight through my cooltubes and outside, all in one system? the plan would be to use 8inch cooltubes for max airflow. anyone have this experience? i dont want to have heat issues first try. also the can max pro series fans..... anyone tried these new models? thanks in advance

Hi all. I have zero experience with lights and indoors, so I need some help please. Been doing much reading here and everywhere else, the more I read, the more I get side-tracked and I can't find information that covers my whole question. Q. Can I get advice on suitable light(s) for 3 - 4 humidity cribs ( enough for 100 clones) and I would like that same light(s) to be used later to Veg 8 - 10 mothers? Just to expand, I have 100 outdoor seedlings, way to many to manage. I want to force sex by taking a clone of each when there a bit bigger ( when I first tip them, I'll take a clone off the top is what I'm thinking). This will get rid of all the boys. I can th…

I just can't figure out this timer... I will post a picture of it and hope that someone else has experience with it. I bought it off eBay, and it has a Growlush sticker on it just like in the picture. If you haven't seen one of these before maybe I can explain the basic parts: - There is a 24 hour dial surrounded by little blue plastic things... apparently you push these things in or out of position depending on whether you want power on during that 30 minute period. - There is a switch between Auto and Perm. - There is a switch that controls on and off for manual control. I've tried everything I can think of and it just doesn't seem to pay any attention to the settin…

So, I've been looking at getting a digi ballast with dimming function, specifically the 600w Lumatek with the 4 settings from 250w to 600w boost, with a Gavita globe designed for digi ballasts. I'm hoping to get some answers to a couple of questions about the effects of using the dimming function, and hoping to avoid a debate about mag reliability vs digi performance. The big one for me is to do with dimming down to lower wattage settings. They say you can use a 600w globe at any setting, or a globe matched to the given setting. I change my globes very regularly, so a short drop in globe life is of no concern to me, so I was hoping to use 600w globes at the lower set…

Hi everybody, I plan on starting my first (semi) indoor grow soon but I'll be transferring the plants outdoors after 2-3 months depending on how quickly they grow so I only need the lights for seedlings/young plants and maybe cuttings in the future. Does anyone have experience using the 80W Philips CFL's (5300 lumens?) for a grow from seed? How many plants per light could I grow in this scenario? Also from reading I've done the light should be 4 inches away from the growing medium when the germinated seed is planted and 1-2 inches away from the seedling once its developed, is this right? Sorry if the answer is obvious but I could only find info on mature plants, not se…

Hey guys, I've been looking around for some time now doing research on cfl light fittings for grows. I've come to the conclusion that it is impossible to buy easy cheap and efficient fittings such as those 2 socket Y shaped fittings the US have. If anyone has knowledge or experience on this topic as to where I could buy some of these bad boys similar to the US ones (cheap effective and easy cfl fittings - up to 80 watts) that would be greatly appreciated. Thanks for your time gang
