Bigger Can Be Better – The Benefits of Buying 20L Nutrient Bottles
Why Bigger Can Be Better:
The Benefits of Buying 20L Nutrient Bottles
If you’re serious about growing plants hydroponically, or any form of soilless gardening such as aeroponics or aquaponics, you already know that consistency is key.
One way to level up your grow game is by buying nutrients in larger quantities and going for the big 20L/25L nutrient bottles.
In this blog we will explain why opting for the larger volume nutrient bottles can make a difference for both hobbyists and professional growers.
These high volume nutrient bottles are especially suited for larger-scale operations or anyone who wants to streamline their mixing and feeding process.
Cost-Effective for Ongoing Grows
Buying nutrients in larger quantities often lowers the cost per litre (see table below). For growers running continuous or large-scale operations, 20L+ bottles offer better long-term value.
Fewer Refills and Less Hassle
In hydroponic systems where nutrients are used continuously, running out mid-cycle can cause unnecessary interruptions. A 20L+ bottle reduces the need for frequent refills, allowing you to focus more on plant care and less on maintenance.
With a 20L bottle, you can mix bigger batches of nutrient solution at once. This reduces the time spent measuring, mixing, and adjusting, which is ideal for growers who value efficiency.
Consistent Nutrient Supply
Larger volumes help maintain a steady nutrient profile across multiple feedings or reservoirs. This consistency supports healthier plant growth and reduces the risk of nutrient imbalances.
Practical for Larger Systems
For hydroponic systems that use large reservoirs, a 20L+ bottle makes it easier to prepare and manage nutrient solutions across the entire setup. This simplifies operations and supports consistent feeding across all zones.
Real-World Example: RDWC Systems
In a Recirculating Deep Water Culture (RDWC) system, maintaining a stable and consistent nutrient mix is essential. 20L+ bottles of nutrients provide the volume needed to replenish large reservoirs effectively, making it easier to manage the system over time.

Another Tip if You're Buying CANNA:
Make sure your CANNA bottles are carrying the UK flag, as they are formulated to suit the typical soil and water conditions found here in the UK. Other countries CANNA will be forumlated for that countries specific water conditions.
