The GP3 Set is Green Planet's complete 3-part base in one box — GP3 Grow, GP3 Bloom, and GP3 Micro together in your chosen size, priced under the three bottles bought separately. Packed with primary, secondary, and chelated micronutrients, pH-buffered for reliable uptake across a wide range, and free of carbonates and synthetic dyes, it suits soil, coco, and hydro in any system. That's the strength of a 3-part base: a more complete nutrient profile, and the ability to give your plants exactly what they need at exactly the right time — the control that crafts bigger yields.

Specifications
- Add each GP3 part to the reservoir separately, stirring thoroughly between each. Adjust pH last.
- Never combine the GP3 concentrates together undiluted — Green Planet warns this can cause nutrient lockout.
- Micro empties fastest since it runs the whole cycle — grab a single bottle of GP3 Micro when the set gets uneven.

Frequently Asked Questions
Why use a 3-part nutrient instead of a one-bottle feed?
A 3-part base gives you a more complete nutrient profile and lets you adjust each part independently, so your plants get exactly what they need at the right stage. That control across the whole cycle is what crafts bigger yields.
What's included in each set?
Each set includes one bottle each of GP3 Grow (2-1-6), GP3 Bloom (0-5-4), and GP3 Micro (5-0-1) in your selected size — the complete 3-part base.
Is the set cheaper than buying the three bottles separately?
Yes. Every set size is priced below its three individual bottles, and the saving grows with the size — the 20L set saves the most.
Do I use all three parts at once?
Yes. All three parts run together through the cycle at ratios set by the Green Planet feed chart — Grow leads in veg, Bloom leads in flower, and Micro holds steady the whole way.
Can I mix the GP3 concentrates together before adding to water?
No. Green Planet advises that combining the concentrates in undiluted form can cause nutrient lockout. Always add each part to the reservoir separately, stirring between each.
GP3 Set or GP3 Starter Kit — what's the difference?
The Set is the bare 3-part base — ideal if you already run your own additives. The Starter Kit adds the full additive line-up (roots, vitamins, strength, and the bloom stack) in a 12-bottle box with the feed guide.
