Im assuming you mean everytime you water or flush there is no run-off and all the water stays in the pot?
If so im sure there are a good amount of drainage holes in the pots.
Also how much pearlite is in that mix? i use a 50/50 mix with pro-miix.
What is the size of the pots and how much water do you give them?
superskunk1 Reviewed by superskunk1 on . water will not absorb out of catch tray! why will my catch tray not absorb the excess water? I can't get any three of my pots. they just sit in the drained water, why is this? i've let them sit for 2 to 3 days at a time also. thanks, if anybody can help! and attached is a picture of my three babies, if anyone can help as to any problems they see.
