I am using the technaflora recipe for success kit for the first time...I am super happy with the kit simply because I was able to buy everything I needed all at once. I didn't get home and realize I had just paid a crazy price for only 2 of 3 parts of a system or something...With the Recipe for Success kit I can look at the feeding schedule and then find whatever in the box...It's super! And my plants aren't dead which is more than I can say about my fiasco trying to use Advanced Nutrients...SO living plants--cheap prices---and an easy to use kit---I couldn't ask for more! And the Root 66 is the shiznit!!!!
