I was thinking about using sand and biochar combined. Not sure what ratio and what type of sand.. The finer the sand, the greater the capillary action. I don't want to use anything that will contribute to water quality degradation, ie., anything with any organics that will break down over time. Thoughts?

<p>I have setup a couple of wicking beds and have found that using gravel just does not work well. Is is too large to allow the capillary action to work and the water just stagnates and does not get up into the grow bed. I am looking for a solution and I suspect that a layer of pea gravel-covered with weed guard- then a mix of sand and vermiculite- covered with weed guard- then the planting soil.<a style="cursor: pointer;"><img src="http://www.bkserv.net/images/Grin.gif"/></a></p>
