here's the pot. also the top of the bin which was hemispherical but i angle grinded the top off to make a collar
which screws onto the lip of the flowerpot which makes the bottom half - and the sawn off top fits snugly inside the top half
here is the light, its a cute little HGL 21X pro. it draws 28 watts from the wall.
back to the top end, and ive cut a hole in the lid of a clip type plastic storage container and screwed it over the fan opening. this is for the home made carbon filter.
here it is with it's base fitted, which has also had a bigger hole cut in it's as the outlet. this is the (as yet empty) carbon filter. i cut up an old can filter to re-use the aluminium grill - which i cut out with tinsnips. you can also see inside where i've hung the light with a chain which comes out and of the hole in the middle and is fixed with a carabina. this allows some adjustment of it's height
