I'm just passing on the idea from an auto-flower grower on another site. It works well. It allows root pruning of the fabric pot. But, without the gnat issues associated with air-pots. And the plastic outside pot helps with the fabric pot drying out. I also run some of my pots as SIP's with a few inches of lava rock on the bottom and a saucer under the plastic pot. They work very well in the greenhouse.Thanks for the idea @Timj
