Great for Indoor/Outdoor Gardens
I make my own plant food mixtures with liquid seaweed for my indoor and outdoor plants, as well as supplementing my AeroGarden veggies for continued growth. This gave me tasty cherry tomatoes for 200 days on my kitchen counter. Now I'm growing herbs, lettuce, and chilies with continuous growth. Very happy. A little bit goes a long way! My houseplants also grow well with these nutrients and I'm looking forward to spring to start my garden outside again. It did wonders for my veggies outdoors. They continued to grow until our first snowfall.

Great for my tomatoes thusfar.
Purchased this so that the tomatoes produced on my plants do not get the dreaded black spots on the bottom. In past years, to my dismay, this has happened. Cannot give my experience yet this year but I have great hopes. So far, the plants look great and little tomatoes are appearing.
