you have a LOT of reading to do ... almost all of your answers, are found in the Basic Growing category, as well as the others ... we are all just members, like yourself, and can't be writing all this stuff, for every new guy that asks ... you understand, I'm sure ...

but, as a beginner, I can tell you, that you need to downsize your operation ideas ... we all kill our first plants, usually from 'overlove' ... KEEP IT SIMPLE ... grow out freebie bagseeds, on a small scale, until you are comfortable with your skills, by that time, you will be much more knowledgeable ... I read almost every grow thread at this website, before I ever made a post ... it was a LOT of reading, but was worth it ... also, take the advice with a grain of salt, like anything, there WILL be some bad info, sprinkled here and there ... use common sense ... there are very few short-cuts, that work in nature ... PATIENCE is the key ...

a 400-watt HPS lamp would serve your cabinet size very well ... around 50 watts per sq.ft. is recommended ... you can use the HPS for both vegging, and flowering (I do) ... ventilation can not be overdone, you need to keep the temps around 75, as much as possible ...

good luck, happy gardening :thumbsup:
