I started 10 years ago with hydro until I had a pump failure and ruined a whole crop. I decided then I needed a more simple way to grow, DIRT! I stay away from the box stores and have been using a formula for 9 years that will produce thru your complete grow period without having to add nutes. I buy Fox Farm products after trying others. They are consistent with their product and have always been super productive. I buy 1.5 cu.ft. Ocean Forrest and 2.0 cu.ft. Happy Frog. Mix with 2 cups of perlite and this will carry you from sprout to harvest. If you are using 5 gallon buckets be sure and aerate (drill holes in the sides near the bottom) and always put about an inch of gravel at the bottom. This will keep you from the deadly root rot. This mixture is good both inside and out. I did not come up with this, I found it one night while I was chasing a rabbit down a hole on the www and ran across an article about the mix.
