Hi guys, long time lurker, first time poster. I've got a 400w MH high bay light that I had done a remote ballast conversion to (thanks cannaversity), and it came with the standard issue 4200k globe. I've tested it and it is all working fine. I ordered a growlush Globe which arrived yesterday, tested it and all good. But I just got home from work to find my cupboard in complete darkness. I removed the globe and refitted the original globe, which fired straight up. What gives? I retried the new globe, to make sure it was tight enough, I haven't touched the glass at all with bare skin, the inside glass bit is still a white/clear colour, not brown or black. Any ideas? Shou…

Howdy Folks, i have just finished my first attempt at cloning, No idea if they will root but fingers crossed i can get half a doz or so to work with, Can anyone tell me if they look ok? i havn't got a heat mat but it is in Qld so is still fairly warm, also i am not sure if i should leave the lid on or not, with the lid off the twin flouro light can get about 6 inches closer to the lil girls..

Hey folks Im considerin a digital ballast purchase would like to pick your brains . Theyve been out for a couple of years at least so reliability issues should to some extent be known by now Im hoping.. From what i can make out... Pro's They run on less power.... thruth? Theyre dimmable... wheres the advantage here? If you buy a 1000w will run anything from a 400w mh to a 1000w hps...... clear advantage Programable even with remote.... could be handy... Cons Price Questionable reliability... ? More prone to water/humidity damage.. So what do you's reckon and what's your experience been with digital ballasts? Cheers -RiverRat-

Dropped in to a local Westaflex store and picked up a "MixFlo" inline fan. Price was only $115 for a 150mm fan. I also got a 300VA fan controller for it ($27.00) The fan is a little loud sitting on the bench running, but when using with the fan controller it quitens down a lot (as does flow of course). I'm keen to hear it once I get it installed with carbon filter and insulated ducting - but that has to wait for now I was surpirsed by the prices I got, as I thought they were quite reasonable. cheers G ...

Hey there, Just looking for some advice for a grow room. Wardrobe is W50cm x D55cm x H150cm. Went to a grow shop and got some advice from the dude, he thought 400w Lucagrow would be OK. He rigged up a quick test in a tent he had, about the same size as my area with a computer fan. Temperture sat at around 32C after about 15 minutes running (read 28C is about optimum), said he'd swap it for a 250w if it wasn't any good, but he's got none in stock. Found him really helpful although I've checked the grow calulator on cannversity and it came back with the below stats. I've also read lumens per square foot is min 3000 to 10000 average, which would put it in the 250W (30,0…

So i looked up the canaversity calculator, and it said for my cupboard to ventilated 49 cubic feet a minute, 1 cubic foot =28 litres, so 49x28=1372L per minute. Is that correct because to me it aeems very excessive, j was gonna put an 8" centrifugal fan on both the inlet and outlet of my box. But there around 350L a minute... Help? Please.

Hey guys, Been awhile since i've posted! I have a some questions to ask; I've found http://www.ausponics...t-growlush.html this HPS which is the difference of getting 2x 130w 2700k CFL or 250w HPS to going along with my already bought 130w 2700k. I'm wanting to hit 300-400w I don't have the biggest height (approx.1m) growbox. I am looking around for wardrobes, dressers if needed.. What are my best choice for 2-3 plants including heat? and where do you get the best prices for a 250w HPS?? Cheers guys & girls

Im looking at replacing my 400w HPS bulb soon and getting a spare for my 600w, Both are HPS Ballasts. Tossing up between getting a 400w son-T agro HPS bulb, or a MH conversion bulb? I will be using the 400w mainly for vegging, and the 600 mainly for flower so will stick with HPS for that What do yas think the best 600w HPS bulb is? Looking at getting a Son-T or any other recommendations? DO ya think its worth getting MH conversion bulb or should I just stick with HPS and get a 400w Son-T? Opinions appreciated
