| I know this is a fairly old post, but I'd like to add a bit of my knowledge. I would suggest buying a Mylar enclosed grow room. IT helps trap heat, and keep bugs out. It also allows you to monitor the exact temperature and humidity within your own container. I also live in the snow and grow tropical plants that need approx 70� with 60-70% humidity. Without ruining the wood or walls in my house, or making my room smell like a butterfly house. Also I went one step further and I use 2x quad band 90watt UFO lights, and 1 tri-band UFO in a tri-force configuration all piled into a 5'x5'x5' grow space. I got a pretty substantial harvest, and my power bill increased approx $30 a month. You can pay the extra for the HID bulbs and my buddies swear by the increased watts that your harvest also increases. So it really depends on the $ ur willing to throw down and to what extent. To me. Let's say 6 months to fruit.. If you have that setup you're probably looking at around 500-600 for a hydro, HID, and depending on your light, you're probably looking at a couple hundred more in power. Is what you're planting worth the investment? Or if you went LED's, it dramatically drops the amount of power consumption and makes that level even more affordable. Also with Led's since they use such a low power. @ some point in the future I want to set up a parallel 12v system tied to a Gear bike generator. So I go and workout in the morning and it powers my grow box. In which you could easily set up for another $200. Enjoy, and any questions or schematics you may want just hit me up. |
