Hey, what better way to learn!

Actually taking the first step and growing a plant is your introduction into the growing world. It's a lot of trial and error.. So next time simply apply what you've learned from the previous grow. You'll gradually learn the basics and then you can apply them however you want.

If you haven't already.. look into getting a book. It serves as a reference as well as a "gro guide". It'll be something that you can look through whenever needed and refreshes your memory if you've forgotten small little tricks and things.

Best of luck,
Bob.
