How Does Growcap Work?
Learn all about how Growcap works and how to use it in your aquarium
Growcap Capsules
Capsules are easy to use. Simply insert the capsules into the aquarium substrate and they’ll do the rest.
As the nutrients spread through the substrate, the roots of aquarium plants directly receive all the necessary nutrients.
This allows them to grow optimally, giving you vibrant plants to enjoy. The controlled release of bacteria directly at the roots creates the most ideal conditions for plant growth.
After approximately 10 weeks, the capsules are ‘depleted’ and you can insert new capsules into the substrate.
Growcap stands out as the only one offering complete plant nutrition in capsule form.
Many other capsules on the market mainly contain iron or clay-like granules. These support plant growth but lack essential nutrients, making liquid fertilization still necessary.
With Growcap capsules, this is a thing of the past.
Add 1 capsule per 20 liters of water every 10 weeks, and your aquarium will be supplied with all necessary nutrients.
Growcap Liquid Plantnutrition
Growcap Liquid Plantnutrition contains the same nutrients as the capsules.
But it’s easy to dose yourself using the measuring cup or connect to a dosing system.
Dosing can be done daily or weekly. See the conversion table for a handy guideline per aquarium volume.
Note: a 100-liter aquarium doesn’t actually contain 100 liters of water, as decoration and gravel take up space.
This prevents overdosing of plant nutrition.
