Hi,
Use household cleaning ammonia. dilute it 4:1 or even 10:1 if you like. Ammonia
is pure Nitrogen. and the plants turn nice and green. It is the best solution.
I also put boratic acid around the feet of my tables so the do not climb up.
I have tried lots of things and this is the simplest and the best, beer didn't
work to good for me.
Jim
