Hi Johnny...
one of the bigest misconceptions about marijuana is the vegging time... You can actually do very welll if you only veg a plant for 14-16 days and have 4-6 nodes... and then switch to 12/12 (flowering).. you can harvest 2-4 ounces... using a simple soil and CFL grow....
The most important factors..
1. pH your water-
pH Water - See More Buds
2. room temperature (70-80)
3. GREAT soil, perlite mixture
4. watering technique... water thoroughly and then let your soil dry... watering a 3 gallon container should be done with at least 1/2 gallon water... to thoroughly saturate the entire pot every watering
5. Light proximity... keep the lights close to prevent stretching and TIGHT nodal growth.. this promotes BIG colas and heavier yields..
6. Steady air flow... have fans blowing air around the room..
