Yeah I understand, thats cool.

I currently have just an open 1/2 inch fitting, and a couple of weeks ago I pulled at least 12 or 18 inches of roots out of there.. The plants in the container are really too big now for me to pop the lid and reach in and pull them again, so I'm just praying they dont clog it.

I'm planning ahead for upgrades and those fittings are definitely on the list.

You're room looks like it's working out pretty well! Plenty of room to grow christmas trees imp:
