Hi

I am building a 1 m2 grow room in an outside location (an out building). I plan on using a 1m nft system, 400w hps with cool hood, 150 fan with carbon kit. I will be growing scrog and think that a meter should be enough height for the set up if I have the screen at 10 inch. I will be lining the box with insulation, plastic sheeting and mylor. There will be a small fan to circulate air and an intake whole(no fan as Im not sure i need it?????). I will have a small heater for the winter months and a small heater for my nutrients. I will have the fan kit on 24/7...?

I have a number of areas I am not to sure about...

Is the light ok or should I go for a 600?

How good are carbon filters really? I need to be super stealth!! are there any other things I can do to reduce odour(I am thinking home made scrubbers/carbon filters/odour killing floro's)?

How noisy will my fan kit be? can it be heard from close by(never needeed one in the past)?

temps often drop to close to freezing in winter, how can i prepare for and deal with this?

Is my room going to be way to low?

Many thanks peeps:rastasmoke:
