Hi all, Im just new and this is my first post so bear with me. Ok, so i'm attempting to grow in my closet in a house with parents and younger brothers and sisters. I've managed to work out a way to keep everything completely steath except for one factor. Im concerned that the fan i use is going to make enough noise for someone to notice in other rooms in close proximity at night or other silent times. Are there such things as silent fan?? that make no humming noise at all.. Any help would be greatly appreciated. Thanks. George.

Hi there, i have 4 plants under a 400W HID in a cupboard, only about 3 weeks old. i have really good exhaust fan from hydro shop and a little desk fan blowing through a hole in the cupboard as my intake... they are about 4-5ft away from the light, i have done this bc i could see the leaves getting a bit scorched from the heat, should i get something more so that i can have the light closer to the plants?? thanks guys...

gidday fellas, After much studying ive decided to build and indoor hydro setup, and was wondering if it is worth me fitting some clear plastic to the flat roof. I have a 400watta which would have to be shaded in a way not to let to much light out through the skylight, I dont really want to have to cover it each night. Any ideas would be much appreciated.
