Granular + Cake

Pot-size-based Granular rates and the Cake finish.

Read text version

How much CropSalt Granular to mix into your substrate at planting, based on pot size, and how to finish with Cake in the last 2 weeks of flower.

01 / granular at planting

Mix Granular into your substrate before planting. The rate depends on pot size: total Granular = pot size × the rate for that size. Rates are grams per gallon of substrate.

Cake for the final 2 weeks

Use Cake at 3 g per gallon of water during the final 14 days of flower (the final 2.5 weeks when flowering runs longer than 9 weeks): 1 gal = 3 g, 5 gal = 15 g, 10 gal = 30 g.

Use RunClean with every feed

Use 0.2–0.4 mL per gallon as a descaler. When using RunClean in place of pH Down, add it until you reach your target pH.

For containers with runoff

Heavier applications and/or a second Granular application may be needed.
