I was just at the hydro shop (a new one I have just found). I still use my old magnetic ballasts, and he told me the new ballasts, whch apparently simpy interchange MH and HPS (not that I use MH), use 25% less power! Can this be true? cheers rob

hwdy guys and gals. have been M.I.A for a while. site looks great. I've got a 2 door cupboard I grow in. I wanna put a board down the centre of it so I can have one side for flowering, one side for veg. I grow with a 400w son-t-agro setup, and i wanna put the same on the other side. r there certain bulbs you use for flowering and veging? Or do I just buy another son-t-agro setup and and just have one side 12/12, tha other 18/6? Do both sides need to be sealed off entirely? (in regards to lighting) Also considering buyin this stuff online. found hydro shops lately are chargin a small fortune. thanks again...

I am currently assembling the grow chamber - But I have struck a problem... The carbon filter is 38 x 38 x 105cms - BIG fucker...and it won't fit in the chamber with the china hat in place. I am considering putting it in the roof above the chamber inside some air-conditioning venting sealed at both ends with the 250mm ducting running from the chamber to the filter and from the filter to the exhaust fan (250mm centrifugal). What I don't know is should the filter be positioned inside the chamber for best effectiveness or will it not matter as long as the path to it is airtight? Also do the filters only suck through the core or do they absorb from the ext…

Hey guys, After a bit of consideration I've decided to try my hand at some growing if its feasable with what is available. I'm not entirely new to botany (was a member of the Victorian Carnivorous Plants Society in my youth) but I have no idea where to start in terms of lighting and whatnot. I have a cupboard which measures H 183cm W 60cm D 50cm. This is very small, I know, so we're looking at what, maybe 1 plant here? Anyhoo, after some very preliminary research I've come to the conclusion that CFLs are what I'd like to go with all the way through the growth cycle (heat and fans and fires aren't things I wish to deal with right now, unless ABSOLUTELY necessary). So, my f…

Hello everyone, My room is nearing its finishing stages and I am about to install the inlet fan but I'm not sure what size I will need as my setup changed a little... The room is 1x1x2.4 by the way with a 600W HPS. I started with the exhaust being a 150mm centrifugal and 300 filter but managed to swap it for a 250mm centrifugal and a 1000 carbon filter. I was going to use a 150mm inlet fan (passive inlets are not a option) but the store guy has said that it won't cope - that I will need a 250mm Red Spectrum inline fan for $190. Is he trying to wring more money out of me or what? Jimbo

Okay, in the near future ill be setting up my first grow room. I have 2x 1000watts HPS ballests and bulbs. I've read that the rule of thumb is 50watts per square foot so my set up should match that. It just seems everyone uses 400watt HPS bulbs. Is this because 2x 400watts are better then 1x 1000watt due to a more even coverage and less hydro? Would a 1000watt yield the same as 2x 400watt bulbs or would it just speed up growth? ...any help is much appreciated Cheers!

Is there a way to tell how much output a used bulb has left? Is there certain signs that say it's dying? Jimbo
