5-1-1 mix vs Earthbox mix
Thank you for so much information, especially Al Tapla. I'm new to gardening with a few DIY earthbox-type containers. I've been frequenting GardenWeb and the Earthbox forum. Earthbox people are very adamant that the potting media should be ~70-80% peat and 20-30% perlite+vermiculite with NO compost and NO pine bark. But here, everyone is of the opinion that pine bark fines are essential to good aeration in a container. I understand that less pine bark and more peat should be used in a bottom-watering SWC to enable wicking, but can anyone explain the vast difference between NO bine park recommended by Earthbox and MAJORITY pine bark recommended here? Any opinion on which is better for wicking-type SWCs in particular?
