I have had my Aero Garden for almost a year now and have had something growing in it almost constantly. The fertilizer keeps the plants healthy and growing.
It is ok. The volumes needed per gallon were too high for my hydroponic system. At the recommended dosage, all of my plants turned yellow. They recovered with a change of water and a lower dosage. Next time I will use about half of what it says.
I love to be able to buy the food in bulk. It is easy to store and easy to handle. The spout pours well and it lasts a good while. Bulk price is also the cheapest, especially when you do not need any seed kits!
