Thanks sooo much guys!
Sloppy G - thanking you, cool that our plants are at the same stage! do u have any pics?
StonedSkunk - cool, will do the flowering in 3 weeks then, more lights - we thought as much. We'll have to pick up some cfl's today. Love the bong smiley by the way!
Squidgey - Great LST link - mucho grassias! Yeah we gotta start doing the fan filter thing soon.
Reefa Cheefa - Cheers for the tips! HPS lamp will have to be bought then so!
Rumpleforeskin - Excellent, flat white paint will be purchased asap. Double in height? Wow didn't know that, thanks, and 60-80 days - check.
Thanks a mill for answering all our queries! Grasscity people rock.
Unfortunately this morning when we went to check on our other 2 (two week olds), one seems to have become rather yellowish. She (Cleo) was kinda yellowy in her new leaves a few days ago but i just presumed it was normal. Please see attached pic of her next to a very green "Alice" - she's much more yellow than the pic shows

.
Any doctors in the house?!!
Also can you buy a budbox that is small, like 4 feet tall? They all seem to be in either large or extra large size. We cant have a huge yield coz of certain factors and don't have a spare cupboard/bathroom/attic/basement - at the mo they are being grown in empty beer boxes. If anyone has any ideas for a new home for Leo, Cleo & Alice your imaginative suggestions would be greatly appreciated!
Cheers peeps!
