Pairs well with
Back Country Blend Boost is the granular PK additive in Green Planet's outdoor feed program — a controlled-release 0-18-19 formula designed to run alongside Back Country Blend Bloom through flower. Flowering plants chew through large amounts of phosphorus and potassium to build big, dense fruit; Boost supplies that spike, plus calcium for cell wall strength and humic acid to move nutrients through the medium. The result Green Planet reports: improved yields, floral development, colour, and aroma. Top dress at 1 g per litre of soil or coco.
Specifications
- Boost is the additive, not the base — keep Back Country Blend Bloom as your flowering feed and layer Boost in alongside it.
- Apply from bud set onwards, when plants start packing on weight and the PK demand ramps up.
- Same granule rules as the rest of the program: back the rate off slightly in hot or wet conditions, and top dress only inside the drip line.

FAQ
Do I use Boost instead of Back Country Blend Bloom?
No. Boost is an additive, not a base nutrient — Green Planet designed it to be used in conjunction with Bloom during the flowering stage. Bloom carries the full feed; Boost adds the extra PK spike on top.
What does 0-18-19 mean?
It's the NPK ratio — no nitrogen, 18% phosphorus, 19% potassium. That's a deliberate skew toward the two elements that drive flower development, size, and nutrient movement during bloom.
How much do I use?
Top dress at 1 g per litre of soil or coco, applied alongside your Bloom feeds through the flowering stage. Green Planet's feed chart and nutrient calculator map the week-by-week schedule.
Does it work in coco as well as soil?
Yes. Green Planet's application rate covers both soil and coco, in containers, raised beds, and open ground.
Is it organic?
No. Like the rest of the Back Country Blend program, Boost is a mineral controlled-release fertiliser with added humic acid — it supports soil life but isn't a certified organic input.
