Hey, I'm new to the forum and cannabis cultivation.I'm going to begin my first grow in about two weeks time.I have decided to grow Northern Lights Autoflower. As I want fast growing plant and have high potency potential.Here is what I plan on getting:Full Gorw Kit & Tent - http://www.amazon.co.uk/Quality-Por...roponic/dp/B004FUIU0S/ref=pd_sim_sbs_lp_1This Kit Includes:- Grow tent: 120x120x200cm - 1x400W Ballast, 1x400W Sodium lamp, 1x Reflector - 1 X 4" Extractor fan, 5M X 4" Ducting, 3 x Ducting clamps, 1 Set Easy roller, 1 carbon filter. I'm going to have the tent in an attic in my garage, the room will not be heated. (Ireland temperatures are cold)I have a few questions i'd love people to answer1. Will this 400w sodium lamp work for Vegetation and Flowering?2. I'm doing a normal soil based grow, can I use compost?3. How many plants can I grow in this tent? I'f I have plants trimmed well and pruned.4. After germinating seed can plant and place it straight under sodium 400w lamp?5. Does anyone have any expereince with Northern Lights Auto?Thanks a million!Chris
