no no! don't make that mistake!
The problem with that hydro system is the reservoir is 2gal. My plants use 20 gallons a week. So with a 2 gal reservoir you will need to stand there 24/7 adding water and adjusting PH. Also this system IMO will tend to cause root rot.
I would recommend the Turbo Garden or there is a similar system called the micro garden. You will have better luck.
If you are a first time grower I would recommend that you use good soil and experiment with hydro on the side. That way you will have something to smoke while you contemplate why the plants in the hydro system died so suddenly.
ebb-flow hydro systems work great and are much easier to set up. If your pump breaks you have the option of using a bucket to manually water.
That is my opinion.
