I am preparing to build a small indoor hydroponic garden.
I'm sure as I progress in this project I will have many questions, but 3 come to mind initially
First a little detail. I am planning this garden as a prototype for a future "off grid" garden. I will have electrical generating capability, but will have to be "careful" of electrical usage.
I want to be able to grow enough tomatoes for personal use 12 months out of the year. So the garden will be small, and needs to be energy efficient.
Q1. I have read that the primary growing mediums are various products that resemble small pebbles. How does the pumped
nutrients rise up to the level of the small plants growing on top of the stomas (or do you
pump the growing chamber so full of nutrients that the liquid reaches the top of the
growing medium ?
Q2. In order to minimize light requirements, is it appropriate to grow "arctic" varieties of tomatoes, or are they heavily compromised as to flavor and texture.
Q3. Since I want to minimize the use of electricity what would be the minimum wattage for an
hps (Or is there something better) light to bring 1 good tomato plant to good production during the winter?
Thank you in advance for your time in helping out a beginner.
