You do not need a liner of any kind. I have never had a piece of hydroton fall out of a net pot. You might try bigger clay pellets (they make several sizes), or net pots with smaller holes.

You can start seeds in hydroton. You lay them on a nylon stocking and put a layer of clay pellets over the top. I've not tried it, but some people do it that way.

I've heard this argument before: You must have a pump in your system somewhere! I'm telling you there is no pump! Whether there is or not, water is took in an intake somewhere. There probably should be some kind of filter at the intake.

People would be wise to consider power failures where they live. Do you live some place that has at least one outage per year? Do you want to take the chance on loosing an entire crop? I usually have 6 or 8 failures per year because I live on the end of the line. Lot's of opportunities down the line for a tree to fall on the lines or something. It made sense to me to design or use a system that has at least some of the roots in water at all times. So I made a hybrid spray/DWC thing, and I have a way of changing the level of the solution for individual plants as the root mass changes sizes. People who live with constant power failures are not really candidates to grow using styles like fog feed or aeroponics, unless they understand that they are taking chances of loosing entire crops.

Opie, I Need A Little Help i figured id ask you because your one of the few who give me good, accurate answers, but anyway its about my rainforest 66, i got my seeds today and began to germ then and i setup the system but its a little different than im use to and, it has CocoTek liners in the net basket then my hydrotron in the cocotek liners, and the spray does not penetrate the cocotek liners and my hydrotron are dry(very dry), now ive only had it powered on for about 12hours but it seems almost like the liners are Rating: 5
