The GreenPlanet Rezin is a flowering additive formulated to support aroma and flavour. It's made from ascorbic, citric, gluconic and lactic acids produced by fermentation, contains no plant growth regulators, and adds nothing to your EC — so you can run it on top of any base at full strength.
Aroma and flavour, without compromise
Rezin is designed to support the natural processes in flowering plants that produce aroma and flavour compounds. Many products in this category contain plant growth regulators, or add enough salts that you have to cut back your base feed to make room. Rezin does neither.
Why zero EC matters
Because Rezin doesn't change the PPM or EC of your solution, you don't have to back off your base nutrients to use it. Your feed stays exactly where your chart puts it, and Rezin sits on top. GreenPlanet also uses it in the final flush week alongside plain water.

FAQ
Will it throw off my feed?
No. Rezin adds nothing measurable to EC or PPM, so your base runs at full strength.
When should I use it?
Through flower, and GreenPlanet's program also runs it with plain water during the final flush week.
Is it included in the Starter Kit?
Yes — the Dual Fuel Starter Kit includes a 1 L bottle.
Can I mix it with another brand?
We don't recommend it. GreenPlanet's feed programs are built around its own bases and additives, so results are most predictable when you stay within the range.
