The bulbs are fun

Sometimes they grow sometimes not. If you are set up to keep a planted aquarium they will last a good while.
You might want to check out the sticky article on cycling your tank in the freshwater forum. Chuck is an acknowledged pioneer in the planted tank field, but I want to point out several things...he has not updated his pages in several years leaving his dosing calculations, methods, and chemicals a little out of date.
Second..the fishless cycle he is proposing is an advanced technique requiring the mastery of estimating needed plant mass, CO2 injection, NPK dosing, algae control, and water chemistry.
I think it is a train wreck waiting to happen for a beginner to jump into that.
There are about 300 submerged aquatic plants available to the planted tank hobbyist. Recommendations really are going to be conditioned on your tank paramaters, substrate, light, anticipated starting plant mass, etc. I would poke around in the planted tank sub forum for some beginning information.
Please do not consider this a nay say, its really a heads up..look before you jump in
Please get back with questions.
