Welcome chef. Have you grown anything else before? Soil grows are easiest for beginners. Seeds, soil, pots and nutrients. Oh and water.

Zandor always says, if this is your first time doing hydro, grow a few soil plants alongside. Hydros ' can be done, but you need alot more equipment. So unless you've got someone close by to hold your hand, it's a pretty steep learning curve. It can be done, but be prepared to spend alot more money.

As far as harvests go, it all depends on the skill of the grower and the quality of plant genetics. Buy some good quality seeds. This will improve your grow tremendously. That is unless, you kill them all.
