Jack's Nutrients 10-30-20 Bloom

Using these dry nutrients makes storing easier. I like that they're designed to be used with tap water. Combining with Epsom salt was easy. Dissolving was annoying and getting the EC right a bit of a process. Results seemed good, though. The company seems responsive and to care about the customer.

I have been using this for YEARS. I use it very sparingly for my outdoor garden only, and it has always worked great. Bonus, you can't get much cheaper.
