116 products
We stock many different types of nutrients designed to supply your plants with everything they need to thrive. But with so many nutrients to choose from, we’re aware that it can sometimes be a bit of a minefield deciding which one to use for indoor growing. For instance, there are different nutrients to suit different growing matter, such as coco or Rockwool. While other grow nutrient solutions are designed to suit both ‘hard’ and ‘soft’ water areas too.
So, to ensure your plants are given all the nutrients they need to grow quickly and maximise their yields, we’ve picked a selection of our favourite nutrient lines that deliver excellent value and cover all aspects and stages of indoor growing.
Critical Mass Systems is always looking at new brands to expand our nutrient range. Below, you can find details regarding different nutrients for vegetative and flowering stages that are suited to a range of indoor growing media. And of course, if you need something that we don’t have in stock, get in touch with us on 0114 3221440 and we can more than likely get it in for you.
Types of Nutrients and Additives for Indoor Growing
Here is a list of the types of nutrients and additives we stock for hydro, coco, soil and organic indoor growing systems.
Base Nutrients
Base nutrients provide the basic nutrition your plants require. These feeds are suited to hydro, coco and soil growing setups. They come in a variety of single, 2-part (A+B nutrients) and 3-part formulas.
Flowering Boosters & Additives
Flower enhancers, additives and PK boosters are designed to help you reach bumper yields when growing indoors. They work with soil, coco and hydroponic media and contribute to a top-quality harvest.
Vegetative Boosters & Additives
Vegetative boosters and additives are handy products that help your veg period go smoothly. They ensure your plants grow strong and healthy and are in prime condition for the flowering stage of the growing cycle.
Root Stimulants
Root stimulants help your plants achieve large and healthy root systems. Healthy roots are essential for impressive growth that result in big yields! But if your plants don’t achieve healthy roots, the plants will never reach their full potential.
Beneficial Bacteria, Enzymes & Other Additives
Beneficial bacteria and enzymes are fabulous little helpers for indoor growers. They can help break down dead roots and other organic material to keep the root zone healthy. And In fact, bacteria and enzymes often make the difference between a good result and a great result!
Nutrient Control & Management
It’s important that you have control over the pH and EC in your feeding solution. Our range of nutrient control products will let you measure and maintain correct nutrient levels and pH levels throughout your growing cycle.
Organic Nutrients
And of course, we also stock nutrients and additives for the organic grower. These include a full range of nutrient management products, enzyme additives and boosters for the vegetative and flowering stages of your grow.
