5 year supply. You need 8ml every 2 weeks for the 6 plant unit. Thats 125 servings. 250 weeks. Looks like a great plant food.....diluted....for my indoor potted plants as well.
I was given a 6 aerogarden for Mother"s Day I love it.I use my own seeds for salad greens and it supplies me with enough greens several times a week for about three weeks;and of course without the liquid fertilizer that would not be the case. Thanks.
