I'm not going to lie, I am having a few minor problems... but I would be with soil as well.
it really dosnt requier much work at all once its set up. just test the water every other day, and fix whatevers going wrong if anything is. and by fixing I mean adding some water, adding some nutes or adding some PH up or down... sometimes its alittle more complicated... but for someone who started using this thing only a few months ago, and knew basicaly nothing about hydroponics, it is easier than soil in a way... I dont have to water them, or anything like that, just test the water... and add some things now and then. and watch the rapid growth... I am doing a graph of hydroponic vs soil tomatoes, the hydroponic tomatoes plant is 3 1/2 feet tall while the soil is 1 foot 7 inches... not as big of a diference with the ganja so far... but certainly a noticable one... jost not 2 times as big...
