Check out the results after 7 days using our SIP design 3. The results were astounding, the side to side with radish of the same variety were smaller and less dense. I think the constant supply of water to the roots was the key. If you look at the picture on the far left below you can see how one of the radishes sent an extremely aggressive root down to directly partake of the water. The pictures below show how this unit was constructed. Really promising results and we are working on the next SIP Design 4 ... this 4th design will be highllighted on another blog this weekend.
The first picture shows the top that has our wick passing through to the top growing tray. Pic 2 shows our wicking mat that sits on the wick coming from the lower watering container. Pic 3 shows the soil put on top the mat for growing. Pic 4 is the shot of the root I mention and shows layer of soil and how the roots have taken over the media. With this setup, you would simply add water into the lower container as needed. The radish are thirsty plants so the water was checked at least daily. Note that the soil was extremely moist as compared to normal, so more experimentation will be done using higher water levels in the soil.
