40 plants are a lot! :-)

I found that if I have to fertilize every month, it won't get done. I use the year long spikes http://www.fosterandsmithaquatics.com/product/prod_display.c... - I don't know if the costs even out or not between the monthly and the year long fertilizers. I try to buy my supplies in September when they are usually on sale.
