Thanks again for the quick reply, Rusty.

About the container size, right now its 23 L. There is a problem that when I try to water the whole pot, the water will run to the sides, straight down the walls of the container, and out of the air holes on the side. I have a bowl shape in the soil where I pour the water, but I dont think I am getting the water to penetrate all of the soil

I think the problem is in the soil itself, and I couldn't find perlite around here. Also, the container itself pretty much sucks for a plant, but it's quite hard to find cannabis-growing materials around here, much less any advanced gardening supplies. Here, they expect you to throw a seed into some dirt and pray. I'll have to see in spring/summer time if there is a better selection of soils and pots, and stock up for the winter.

Lights are off for the night now, but first thing tomorrow morning I'll flush it out, see what happens.
