(Sorry about the Auto-Start on the Video. Don't know how to turn that off–Rick).
I've set up a hydroponics (soil-less growing in an inert medium) system inside the tunnel, which is itself inside my greenhouse. This is a little video on how I did it and how the system works. For early season vegetables, this scheme will work all the way up to Maine…at least that's what Eliot Coleman says. You can have, however, just one or two Dutch Buckets (also called BATO buckets) in a corner of your house. Just as long as the temps stay warm enough for, in my case, tomatoes and peppers.
There are some parts coming that are not in the video. One is an aquarium air pump to keep the growing liquid oxygenated. The other is an aquarium heater, which will warm the solution that is pumped over the roots.
Also I failed to mention that this system doesn't run continuously, it is On 1 hour, Off 4 hours.
- It used to be that you couldn't find drip irrigation supplies at garden centers and the big Orange or Blue stores, but now you can. However, you can order drip supplies from Drip Works online as well.
- The Dutch Buckets came from Grower's Supply, but there are many sources (be sure to order the siphons, 2 per bucket, which are separate). There are also videos on how to make home made Dutch Buckets (BATO buckets).
- the Hydroton came from a local hydroponics store, but is also widely available on-line. You can also use any light medium, such as expanded shale, perlite or even river gravel (anything without limestone. To test, put a hand full of gravel in a jar of vinegar. If it bubbles and sizzles, you can't use it.)
