Hi Super,
You will want to purchase as may CFLs as you can.. The 42 watt/150watt (2600-2700 lumens) bulbs at Home Depot and Wall MArt work great ($5-$10).
If you Flower your plant when it is 6-10 inches, with 4-6 nodes, and surround your plant with 2 - 8 bulbs, keeping the bulbs less than 1 inch from your foliage, you will have a wonderful yield..
probably 1-3 ounces depending on your strain.
NOW... this will only come true if you use proper watering technique..
and NOW you KNOWM
