id go with what chronikz said. get a milk jug or a bigger jug, fill it with water and puncture it with a tiny nail and set it next to the base of the plant. it will slowly (smaller nail the better) drip out hopefully over a few days
Alright.... I've got a couple of experiments at home going on right now seeing which one will work the best but I've been using sewing needs to make the holes lol
