best venting is either the sewers, (be carefull of where your drains are outside...) and chimney (the smell is over head and difficult to pinpoint) but you cant take out bricks from a chimney however you like.
if you insulate your grow area then ventilate a sealed area on the outside, i was considering the application of a vented tent covering a celotex room with cool tubes. then cover with an IR proof covering, if you have anymore applications please let me know.
you won't get any light onto your top plants at all, it's because your light's are going to be lower than the edge of the bucket's you'r better off with cfl's strip lights, look into aquarium lighting for a bit of an idea.
Im thinking:
bat guano
caster worms
perlight
and some regular potting soil.
does anyone know a good ratio to start with ?
im intending to use aero pots indoors and i would like the best results possible.
i've heard of "dutch dirt" which gave me a soil recipe from scratch. but i can't find...
not designed yet but my principle is there ... so im thinking of converting my attic into a grow room, risky i know but i have no other area that's indoors. but anyway the important thing is i have to share with you this great idea. using aquarium lights for vegging is probably going to be...
sounds ok. but it's not all about the figures man.. you need to see what your plant/ strain responds to. some plants much prefer the more humid hot climates and others cooler and dryer.. it's all about getting to know your strain.
just did a noob move. i just bought a high pressure mercury balast and fitting for £15 i just found out after i baught it. is the balast usable for anything else? a ballast is just a massive resistor right? would i be able to put a MH in it or many something smaller or larger that's the same...
i know you've already chosen... but to thoes who may chose 250. just get the 400w as your not gona be happy with the 250 if you want 4 decent sized plants.
i'd just like to say im using a 300w cfl and that im set up now, however its just occurred to me that i'd need some way of increasing the amount i grow without increasing the amount's of lights i own. i may buy one more set of lamps however im using cfl's and would love to maximize my grow, i...
yeh i can agree, try not to nock off too much soil if your root's arn't bound. and things should be plain sailing... i would query the benefit though at this stage. would it be worth the trouble for the amount of good it's going to do?
i live by elastic bands... during vedge, as soon as your plant starts to get close to the light pull it down. and when flowering pull all the bottom branches up towards the light in an even coverage (the more even the more bud), you can look see what sort of harvest you'll get if you go on the...
i think the main problem here is that you get water dried up in your pots which leaves salts behind. this is bad. but if you treat your soil a little bit yeh you can use it again... is it worth the extra effort rather than buying a new bag for 3 quid ... hmmm no probably not.
