Summary

This is a modification for those liquid miracle grow bottles (https://miraclegro.com/en-us/shop/shop-all/miracle-gro-liquafeed-all-purpose-plant-food/2004325.html). Print this, cut the end off a miracle grow liquid bottle that is empty and glue/epoxy this print on.

Below is a thread I used to mix up my own liquid miracle grow:

Basically I'm using 6 of the big scoops (1.5 TBS per scoop) of powdered Miracle Grow per 1 gallon of water. I mix that in an extra 2 gallon drink dispenser and fill my miracle grow bottle from there. I have 6 4ft x 8ft raised beds as my garden that uses soaker hoses and a timer for water. I water 8 minutes, 2 times a day.

I have an inline injector for the fertilizer. (https://miraclegro.com/en-us/shop/more-from-miracle-gro/miracle-gro-liquafeed-universal-feeder-w%2F-liquafeed-all-purpose-plant-food/401910.html) I refill my bottle once a week on Friday. I have the injection rate set so that the bottle is typically empty by Sunday afternoon.
