Recommend a Fertilizer Injector

gentleben · April 4, 2019

For the last couple years I have grown my tomatoes in fabric grow bags filled with Al's 5-1-1 mix. I have drip/sprayers set up for watering and been fertilizing by had with TTF.

This year I want to improve my yield by:

adding a fertilizer injector
pruning to two stems per plant
growing two plants per large container
fertilizing with Hydro-gardens 4-8-18 plus Ca(NO3)2 and MGSO4

I've searched here and other places and most recommend going with a dosatron unit, my main question is which one?

I will be growing about 18 tomatoes plus some herbs, lettuce and strawberries.

Any help on picking a unit would be appreciated. Do I need adjustable flow rate? What size of mixing container should I be planning for?

here's a pic from early in the growing season last year:

Thanks for any and all help, this is my first post, but I have been lurking for a while now and learned a lot.
