Thank you so much for the detailed reply. I have downloaded every book I can get, but it's odd that there doesn't seem to be a real straightforward answer on some of my more basic questions.
Let me try to be very specific and would love your input:
I'm putting together a crappy outdoor greenhouse (PVC and plastic). I was planning to use a large rubbermaid storage container for a
nutrient solution and
pump it into 4 foot lengths of 4 inch PVC tubing. I was thinking each shelf could hold two of these tubes and I would end up with 4 tubes.
I would love to plant lettuce, spinach, peppers, basil, and tomatoes. Note: this is based on my own eating preference rather than any hydroponic expertise.
I expected to use a single pump to pump the solution into one tube on each side and let gravity allow it to flow through and drain back into the reservoir.
Comments, feedback? Will I end up with yet another round of dead plants and a failed foray into a new hobby?
4 inch tube, 3 inch netpot, clay pebbles, flora grow
nutrients.
