Depending on how serious you are about indoor gardening, you may want to set up an entire unit that is dedicated to it (which is essentially what a greenhouse is). If you are going to do so, however, there are some vital pointers that you will want to keep in mind. To start, ensure that the area is adequately insulated and also ventilated. After all, the air will need to be vented out and replaced with fresh air. Additionally, ensure that your unit is powered through a GFCI outlet and also think about where you will want the reservoir to be located. These are really just some of the things to keep in mind. Then again, if you are just looking to grow a few herbs here and there, a full-fledged system like this will be overkill.
