Use strips of velcro that you can buy at any hardware store and use it on all of your joints of the cupboard. cut intake and exhaust holes at the back if possible. cover them with angled cardboard to still alow airflow but minimal light escape
roll a joint and smoke it, if it burns evenly and a decent pace than it should be fine. if its hard to keep lit and burns fucked u still need to cure for a while.
when you smoke a joint, put an ash in your hand and squish it, all the ash that isnt white is chemicals:)
as far as the smell goes, your plants will smell. if you live all alone then this is not a problem at all for a small grow. you would not be able to smell it in the next room unless its dank ass budd. if smell could be an issue for you then odour absorbers work good but the best is a carbon...
if anything i would put a fan at the exhaust hole sucking the air out. it is much easier to pull air than to push it. if you have a fan sucking air out the top it will automatically draw air in through your intake holes at the bottom. if you only want 1 fan in your grow space this is the msot...

sorry 1000 ppm is the range you want for aggressive full vegetative growth. what conversion factor does your meter use because that will give you completley whacky answers.
they are usually either .5 conversion scale or .7 conversion scale.
if you have a .5 conversion scale then in DWC with...
Single ended Metal Halide HID lights give off almost no UV rays.
"Do metal halides need a UV shield?The outer envelope of a single ended metal halide bulb filters out most of the UV rays emitted from the arc tub. Double ended bulbs on the other hand do not have an outer envelope to filter UV...
you dont need to run your duct pipes out side just make your the air in your grow space is being changed quite often. running duct pipes out windows is really suspicious and when your plants are flowering you would need to get a carbon filter. i would get a thermometer also. make sure your...
If you really want to get one i would go with the second one just because it is a bit bigger
