I'd like to try DTW hand watering

Batch 64 has 3 mediums so if one is better let me know.

Medium:

check out growstones. i use them in dtw hempy buckets. hold most air and water of any medium. made in USA too and super easy to re-use

i use grow stones 70% coco, 30% grow stones, i rate them

I use 100% coco down to the bottom in fabric pots. By adding pebbles to the bottom all you do is shorten the pot. I do post mortems on all my containers and have never found rootballs extended out of the coco and into the pebbles. Drainage is the same with or without.

I'm running cocotek brick I brought back with water and 3 parts coco one part perlite. Three gallon fabric pots and Nova grow/bloom and loving life.
