Seemingly just the information I've been looking for regarding pot material and watering. As suggested by member Gerardo above and a few others elsewhere, these 'root bags' or 'fabric smart pots' can be placed into single pot saucers and watered from below by adding water to the saucers?
If this is the case, I'd love to use pictured 'root pots' and saucers below. Does one just insure saucer is say, half full all the time and check top soil by poking finger to check moisture? My concern is should there be any water remaining in saucer shortly after watering? Would that be OK?
