im using 3 x 75 watt flourescent tubes, two overhead plants and one behind at a side angle with reflective soil , im using a mature plant compost great for flowering plants with styrofoam chips and large stones in the base for drainage the plant on the left is draining perfectly but the other one isnt draining at all? would it maybe because the other plant is a lot stockier and taller and uptakes more through its roots?@
