I dont care what anybody says.....dirt is easier than hydro

As far as which dirt to use...try sunshine professional mix #4 Sun Gro Horticulture | Products | | Sunshine® Natural & Organic Mix #4

And fertilizers try the greenleaves brand ....grow juice for veg....bloom juice for bud....boost juice adds vitiamn b Hydroponics, Indoor Gardening Supplies, Hydroponic Systems - home

Reason for my suggestions.....the soil I have used for years and is rated # 1 amoung growers.

The fertilizer is the only 1 that will tell you your waters ph by changing the color of the water. Greenleaves is pH buffered to correct most pH problems and has a unique visual color indicator for instant pH assessment.

Bloom Juice contains a color coded pH monitor which yields acidic pH (6.0-6.5) when mixed with distilled or tap water. The applicable color scale and corresponding pH are as follows: yellow: PH 6.0-6.7; orange: PH 6.8-7.8; purple: greater than 7.8
I use 12 inch potters and get 6-8 oz per plant under 1000 watters
