I am experimenting with deep water culture hydroponics and, so far, am very pleased with the result. I'm setting up a second system to use in the spring to start some new tomatoes.

I thought I'd share what I'm using for anyone who is interested.

Image

I am using an 18 gallon Sterilite bin for the nutrient tank. Here are some of the other components. Missing components: aquarium air pump, air line and air stone.

Image

Bin with 2 five inch net pots inserted.

Image

Drip ring irrigation components. The half inch tee is connected to a circulating pump to continuously feed nutrient to the net pots. The 1/8 inch tees with a little tubing were inserted into the tee and sealed with silicone.

Image

Drain plug to replace nutrients.

Image

Drip rings completed. They need to be just a little smaller than the net pots.

Image

Drip rings in place.

Image

System completed. Not pictured: An air line is fed through the existing hole in the Sterilite handle and an air pump and an airstone is attached. The airstone I use is 8".

Cool system Mike.

Are the roots going to sit in the nutrients like a raft system or bucket DWC?

How do you keep the pump from overpowering the drip lines with too much pressure?

Do the dripp lines run continuously?

Thanks in advance!!

Hi Halfway,

When I put the plants in the net pots, they are growing in rock wool cubes. The cubes sit on the bottom of the net pots and I fill around them with hydroton. Only fill to the top of the rock wool cube, and as they plants get bigger, I add hydroton until it gets to the top of the net pot.

I bring the water in the bin up to the bottom of the net pot and mark the drain tube at that level so I can tell how low the water is. I believe it would be OK to lower the level of the water once you've gotten a good root ball going.

This particular circulating pump has a connector with a valve so I can adjust the flow of the water. The circulating pump runs continuously.

I've updated my original post on the tomatoes so you can see how they are doing. Keep in mind that the plants were set in the net pots on 10/28. I had no idea they would grow this fast.

Well that's the idea of learning from experience. It makes you determined the facts that do and don't in actual performance. It is more wise to do this most of the times.
