Of course - you can use whatever you wish - no need for permission or approval.

Wasn't actually seeking "permission" or "approval".........

Ok then - 'YES' (affirmative - offered neither as permission or approval).

Check out the earthtainer construcion guide for some mix info for a self watering planter, or just search container mix. Most will be a soil-less mix, there are a ton of great threads on here regarding container mixes, fertilization, and also water movement/retention. The poster above "Al" has some very informative and detailed explanations. It seems like gardening is such a varied and expansive topic that searches very rarely yield a simple, direct clear answer to a question. The answers I have found have been partly from searches, partly from posting a question, and partly from reading older posts ( sometimes not directly related to my original question ). There is an enormous wealth of knowledge here, take advantage of it, I did and have learned alot.

Thanks suburbangardenMD for the input! While I'm new to container gardening, I've relied on GW for a host of info in other areas of gardening & landscaping. Much of my knowledge has came from the sources you've mentioned.

where is the like button for Al's posts ?
