Burmeseanswered grow question 3 years ago Hi there, IMO if you want a good drainage pot, go 1:1:1 ratio for soil,coco,perlite.And If you want a best drainage go 70/30 coco/perlite mix.I sometimes get problems with poor drainage ,especially when I want to grow orgainically with dry organic amendments.Too much dried organic matters make the soil hard and difficult for water penetration.BTW I always put marble stone at the bottom of the pot for extra good drainage.Good luck and happy growing... ✌️
