So far I like the waterfarm systems. I dont have any separate reservoir or controller. I just bought the two units and plugged each of the air pumps into a separate plug.

The waterfarms come with everything you need....Except for a meter that will tell you the PH and PPM (strength) of your nutrient solution. This almost killed my plants. I mixed the nutrients in the kit at the strength recommended by GH. My plants never seemed to really take to this...infact they showed signs of burning. When I finally bought a meter I found that my PPM was 1900 when it should have been closer to 500.

The other problem I am having with the waterfarms is figuring out the proper watering schedule. I started out with the air pumps on all the time. This left my plants looking way overwatered (and burnt due to the PPM). Yesterday I put the water on an hour on hour off timer and this didnt dry them out at all. Today I put them on a one hour on, two hours off watering schedule.
towel Reviewed by towel on . My first grow: 2 hydro, 2 soil (how do they look?) I brought four clones home on 1/20. Two of them are G-13 x mango and the other two are Romulan Haze. On 1/22 I bought 2 waterfarm hydroponic systems. I put one of each kind into a waterfarm and mixed up the nutrients recomended by General Hydroponics using distilled water. I left the other two in the cups I bought them in. I plan to transplant these two into three gallon pots in a few days. I am currently vegging them under a 400 MH supplemented by 4 23w CFLs. As for ventilation, I Rating: 5
