Cyco Nutrients - Platinum Series - Potash Plus - Early-Flower Potassium Booster for More Flowering Sites
Best for: growers wanting to build more flowering sites in the first weeks after the switch to bloom.
Our thoughts
Potash Plus is a timing-specific additive, it does its job early in flower rather than throughout, so don't expect it to double up as a late-flower PK booster. If you're running a Cyco base feed and want to make the most of the transition into bloom, this is the additive that's built for exactly that window.
Potash Plus is designed for use in the first four weeks of the flowering stage. Potash (potassium) plays a role in water retention within the plant, which in turn improves how well nutrients move through it, and Cyco's formulation also has a balancing effect on other nutrients, particularly nitrate, which helps improve overall nutrient uptake during this transition period.
The main practical benefit is speed: by supporting the plant through the veg-to-flower switch, Potash Plus is formulated to help speed up the development of flowering sites early on. More flowering sites established early gives the plant a bigger foundation to build flower and fruit mass on for the rest of the cycle, which is the logic behind using it specifically in this early window rather than throughout flower.
How it compares
Early and mid-flower PK boosters are a crowded category, and Potash Plus competes with some well-known names.
- House & Garden Bud-XL is a widely used flower-development additive aimed at a similar early-to-mid flower window.
- Aptus Super PK is another concentrated PK product growers use around the same growth stage.
- Advanced Nutrients Big Bud covers similar territory, though it's typically marketed more toward overall bud size than specifically flowering-site development.
Where Potash Plus differs is its specific four-week early-flower window, so it pairs well with a later-flower PK booster like Swell rather than replacing one.
Usage guidance
Stick to the early-flower window this product is designed for.
Timing
Start dosing at the point you switch your plants to a flowering photoperiod, and continue for roughly the first four weeks of flower.
Dosing
Follow the dose rate on the bottle or Cyco's Platinum Series feed chart, adding it to your existing base nutrient solution rather than using it alone.
Following on
Once you're past the early-flower window, transition to a late-flower booster such as Cyco Swell rather than continuing Potash Plus indefinitely.

- Growers who already use a late-flower PK booster and want to cover the earlier window too
Our take
Potash Plus does one specific job at one specific stage, and does it without overcomplicating your feed schedule. It's a logical add-on for anyone already committed to a Cyco Platinum Series routine.
One we sell a lot of for growers timing their flower additives properly. Worth picking up for this year's flowering run.
