Hey guys and gals! I am a lifetime smoker (at heart, at least, when I couldn't in reality) who is building my first grow box from scratch. I only want to grow like 2-3 plants - in case one fails- for personal use. I do smoke quite regularly, maybe 2-3 oz/month, and don't need research lab grade potency (though I like strong bud as much as anyone else!). I have a few questions and am open to suggestions... 1. I am going to go hydroponic, and have selected either the General Hydroponics (GH) Powergrower or GH Waterfarm. Am I an idiot for narrowing to these or are they pretty solid choices for a home 2-3 plant grow? And is one better than the other or grow larger plants? 2. I have budgeted for a HPS lighting system, but in researching and reading, I have heard that a pure CFL system, paying close attention to the color ratings, can be used throughout the grow. I have also heard that you can use CFL for vegging and HPS for flowering. However I would LOVE to avoid the heating issues HPS and MH bring if at all possible. Thoughts? 3. My cabinet will be: W 5' X L 4' X H 7'6" with about 20 sq/ft growing floor (4' X 5'). I will have about 4' to 4.5' from hydro-pot top to light hood bottom, so I'm thinking I have at least 36" of growth room before the tops of the plants get too close to the light. How much smoke-able bud do you think I'll get from two plants with 3' to grow and about 3' - 4' to canopy? I know it's not an exact science, but assuming I do things in an overall "right" way, what do you cats think? 8 oz? 16 oz? More? 4. Is a CO2 generator necessary for a 2-3 plant grow? I have seen that a good air exchange gives enough CO2 to the plants, especially for small grows with large cabinets/rooms. I have also seen that the "yeast jug" method works very well for small grows. Anyone have experience in comparing the two? I am willing to invest the money to make it right (to an extent, of course, lol), so if you have good tips that mean added expense for substantially better bud or substantially easier and dependable grows, I am all ears and willing spend the extra bucks. I will probably be on and off the board as I build with more questions, but I would REALLY appreciate the opinions of my seasoned "brothers-in-toke" on these few starters!
