Growing Hydroponic

In hydroponic growing What is the difference between drain to waste and recirculatingprograms?
With either system you start out the same. Take several gallons of fresh water, mix in the appropriate nutrients and you are ready to go for several days or weeks.
Typically, in the case of drain to waste, the roots of your garden would be growing in something like a bag of pearlite, bucket of shredded coco husk or rockwool slab. In order to deliver the aforementioned nutrient solution into the root zone you would have a system of small tubing, float valves or drip emitters. This provides a continuous supply of water droplets that maintain a damp but not water logged growing medium. This being necessary to maintain an appropriate ratio of oxygen and water along with the nutrients the plant needs. People call this drain to waste because once the nutrient solution is applied to the roots it's gone, you won't be getting it back. In some systems you may have a catch pan that collects excess runoff but this should be discarded. One factor that makes drain to waste appealing is that you could mix a large tank of nutrients with all the variables dialed into your liking and you can leave it for an extended time. The pH and nutrient content won't change on it's own, for example. Drain to waste kits are generally cheap, fairly simple and are good to start with if you have only a limited number of plants. This is an example of tomato plants growing in rockwool slabs, common in commercial hydroponic operations. Once the nutrients have drained into the slab of rockwool the used nutrients will need to be replaced with a fresh batch at some point in the future.

Recirculation system can come in several forms but all basically apply the nutrient solution repeatedly. This could either be the roots being suspended directly a bucket containing nutrient solution or plants that are in a container which is flooded and then allowed to drain several times over the course of the day. Check out these pictures for a better idea:
http://www.hydroponicist.com/hydroponic-systems/images/aero-pod-bubbler.jpg
http://www.hydroponicist.com/hydroponic-systems/flood-and-drain.htm
If the pictures look at all complicated, don't worry, there is really nothing to it. With a recirculation system you need to regularly check the pH and conductivity levels since the plants will be absorbing nutrients at differing rates and the chemistry of the solution will be in flux and thus require some minor adjustments to keep the plants happy. Nothing the average person can't master though! Hobbyists with a large number of plants typically use a recirculation system since one one water supply can feed a large number of plants where a run to waste system will usually have one water supply for something like 1-6 plants. If you have 30 plants that's 5-30 water reservoirs you would have to take care of using a typical hobbyist drain to waste system compared to just 1 water supply in a recirculation system. Another advantage with recirculation based systems is that, with some experience, you can stretch a little water a long ways.
Hope that helps!

Hello there,
I had a conversation with John Newling. We were both in Nottingham giving a talk. I gave him a book of a show I did, and he gave me a book of a show he did. It was a fair exchange. I mention it because his project was about growing hydroponic vines that are from nowhere. The future of the project is to rove, perhaps they can say hello to your lettuce patch.
