i have my walk in closet as a grow room, it is about 5ftx5ft. everything but the carpet is painted white so light can reflect off of the walls. i am planning on growing 3 skunk plants. i have 3, 3gallon pots that have a mixture of 25%perlite and 75% miricle grow seed starting soil. will be watering with distilled water that is airrated. the ph is a little under 7. the light setup i have now is just a workshop with 2 32watt t8 with cool white bulbs for veg and will add 2 24" flurescents for flowering. Is there anything i can do to improve my setup, trying to keep it as low cost as possible. also any comments on dr. earth bat guano 10-3-1 thinking about using. thanks
