Noob here - thanks for all your info so far - it is great.

My space will be limited - 550mm width by about 1600 high by 900 length.

I'm going to try aeroponics with the setup like this:How to build an Aeroponic system | Alternative Innovation

4 Plants.

I just bought a LED off ebay here: @NEW 225 LED Hydroponic Plant Grow Light Panel Red/Blue - eBay Lights, Hydroponics, Gardening, Home. (end time 09-May-10 14:16:56 AEST)

and realize this probably isn't that great quality - so now I'm thinking what LED/s I should use - or a combo of other lights - ie one for veg and one for flowering. You guys just have so much knowledge sometimes I don't know who to listen to! :P

Anyway any help would be much appreciated.

My main concern was heat - thus LED or maybe something else?

I'm in Australia if that helps?

Thanks again guys
