Dry Fertilizer for Cannabis Cultivation
Three parts. One feed program. Every strain.
By the time you add supplements and additives, most fertilizer programs run six to twelve parts. Rx Green’s dry fertilizer line runs three: Part A, Part B and PK. Part A and Part B run their own stock tanks, unchanged from veg to flower, with PK in its own tank during flower only. That is the entire system.
Formulated and trialed on cannabis to drive yield, terpene expression and total active cannabinoids. Høst Cannabis in Denver has run more than 40 strains on it for over two years.
Why it stays simple
- Part A, Part B and PK each hold their own stock tank at 100x, and A and B never change from veg to flower.
- The same injector setting runs every part, so a doser is set once.
- Dissolves clean, so lines stay clear and there is no mid-cycle line cleaning.
- No pH adjustment needed when your solution sits between 3.5 and 6.0 pH.
- A complete profile, so there is no stack of standalone supplements to source and mix, and fewer separate inputs means fewer chances to push one element into nutrient antagonism.
The feed chart runs clone to finish, with a mixing chart for any target EC. Fewer parts also means fewer bags to buy, stock and reconcile, and a program that a new hire can run correctly in the first week.
What it costs to run
Meaningfully lower cost per gallon than the leading brand, on a program with fewer parts to buy and mix. Ask for the cost-per-gallon breakdown at your feed strength and room size, and for how the three-part line compares with running liquids.
Two-plus years running at Høst Cannabis
Results, not adjectives. Høst Cannabis Co., a boutique cultivator and wholesaler in Denver, moved its entire garden onto the Rx Green dry line and reports:
- 40+ strains on one feed program
- Zero clogged emitters
- Zero yellowing, zero uptake problems
- Zero mid-cycle line cleaning
“Consistency is everything when you’re running 40+ strains, and Rx Green delivers that consistency every time.”

Tested before it ships
Every batch of Part A, Part B and PK is third-party lab tested for guaranteed-analysis accuracy, heavy metals (Pb, As, Cd, Hg) and contaminant screening, with a Certificate of Analysis available for every lot. The full protocol is on the quality control page, and COAs are in the COA library.
