my very first grow ever was with one that looked like that but it was a hydroponic drip-kit. the kit ended up working very well. if you go from growing in soil to growing in some type of hydro system you will see how big the plants get at such an early age. the only problem i ran into with the kit was once the plants started hitting about 3 weeks old the roots in the reservoir started getting matted together, and eventually shaping the form of the res. the bad part about that was i had 6 plants in the kit and only one turned out to be female, so i had to cut the roots from the other plants away from the female roots. other than that you should have a good grow with those kits.
