Green Planet Nutrients

Two base lines, and a dry option

Pick the base first. Green Planet stocks more than one kind, and the rest of this shelf follows that decision.

GP3 — three part. Grow, Bloom and Micro, each bottled in 1L, 5L and 20L. You change the ratio yourself as the plant moves through the cycle. All three come together in the GP3 Kit, and a complete three-part starter kit sits beside it.

Dual Fuel — two part. Two bottles instead of three, for growers who would rather measure fewer bottles and make fewer calls. Sold as a set, with a starter kit and a larger kit that folds the additive range in.

Back Country Blend — dry. Grow, Bloom and Boost as dry powders, bagged from 5kg to 20kg. Freight and storage cost far less than liquid, which is why it suits anyone feeding at volume or growing outdoors.

Horti — dry, professional. Horti Grow, Horti Bloom, Horti Late Bloom and Horti Cal in 2.3kg tubs, plus Horti RawK from 100g to 10kg.

The additives

The bloom booster this brand leads with is Massive Bloom Formulation. Liquid Weight and PK Spike work the same late-cycle window from different directions; Rezin is written for late-flower quality. Calcium and magnesium sit in Pro Cal, which coco and soft water both need. Vitathrive covers propagation, Root Builder the root zone, and Plant Guard the protective job. Ocean Magic, Karbo Boost, Bud Booster and Horti RawK round out the rest, most of them from small bottles up to bulk sizes.

Media, from the same brand

A nutrient brand that also makes the medium is uncommon. Green Planet does: Professional Coco Coir and a 70/30 Coco Perlite Blend in 53L bags, 60/40 Coco Chips, and 8–15mm expanded clay balls in 25L. Matching feed to a medium written for it is convenient if that is how you want to run — more options live in Coco Coir & Peat and LECA Clay Balls.

Choosing between them

1. New to the brand? Dual Fuel. You measure fewer bottles, there are fewer ways to miss the ratio, and the starter kit already includes what you need.
2. Want to tune the feed? GP3. Three bottles let you change the balance yourself as the plant shifts through the cycle.
3. Feeding at volume? Back Country Blend or Horti. Dry mix costs a lot less per litre of finished feed and keeps in the tub indefinitely.
4. Growing in coco? Put Pro Cal in whichever base you run.
