Green Planet Feeding Schedule

About Green Planet Nutrients

Green Planet is a Canadian company with an unusually broad range for its size — they make a one-part, a two-part, a three-part and a full organic line, which means there is a sensible Green Planet program for almost any room. They are also the people behind Massive, one of the most widely used bloom boosters in the hobby.

Terpinator and Purpinator come from the same house, which catches people out — if you are looking for a Terpinator chart, it lives in the Green Planet family.

Lines we carry

  • GP3 — the three-part base (Grow, Micro, Bloom)
  • Dual Fuel — two-part, for growers who want fewer bottles
  • Medi One — a genuine one-part for the simplest possible feed
  • Backcountry Blend — the organic dry line
  • Horti Line — built for commercial rooms
  • Massive, Terpinator, Purpinator, Vitathrive — the additive range

Reading the schedule

Each line has its own chart, so start by identifying which base you are running — the rates are not interchangeable between GP3, Dual Fuel and Medi One. Additives like Massive and Terpinator sit on top of any of them.

Green Planet's charts are generous. If you are on soft water or a light-feeding variety, start at three-quarters strength and work up.
