Description
Fast-Acting Flushing Solution for Cleaner, Better-Tasting Harvests
Bio Diesel Crystal Clear is a specialised flushing and finishing solution designed to quickly remove excess fertiliser salts from coco coir and peat-based growing media. By helping break the ionic bond between accumulated mineral salts and the growing media, Crystal Clear allows nutrients to be flushed away efficiently using significantly less water than traditional flushing methods.
Formulated with a blend of complex sugars, Crystal Clear also supports increased Brix levels, enhanced terpene production, and improved colour expression during the final stages of flowering. Whether correcting nutrient lockout, performing routine salt maintenance, or preparing plants for harvest, Crystal Clear helps restore nutrient availability while promoting cleaner, smoother-tasting flowers.

Why Choose Bio Diesel Crystal Clear?
Over time, mineral fertilisers can accumulate within growing media, reducing nutrient availability and leading to deficiencies, lockout, and reduced plant performance. Bio Diesel Crystal Clear is formulated to rapidly remove these accumulated salts while using only a fraction of the water required by conventional flushing methods. Its unique formulation also supports improved flavour, aroma, colour, and overall crop quality, making it an ideal solution for both maintenance flushing and harvest preparation.
Application
Nutrient Lockout
| Application | Rate |
|---|---|
| Crystal Clear | 5ml per litre of water |
- Do not adjust the pH.
- Flush with at least 5 litres of solution per 50 litres of growing media.
- The following day, resume feeding with fresh nutrients at half strength and a pH of 5.8–6.2.
- Maintain a reduced EC/PPM until plants have recovered and resumed vigorous growth.
Mid-Cycle Salt Maintenance
| Application | Rate |
|---|---|
| Crystal Clear | 5ml per litre of water |
- Use periodically during aggressive coco feeding programmes to remove accumulated salts.
- Do not adjust the pH of the flushing solution.
- Resume normal nutrient feeding with a pH of 5.8–6.2 within 24 hours or at the next irrigation.
Final Flush (Last 7 Days)
| Application | Rate |
|---|---|
| Crystal Clear | 5ml per litre of water |
- Apply three times per week during the final seven days before harvest.
- Do not adjust the pH.
- Complete the flushing process with plain water before harvest.
FAQs
What is Bio Diesel Crystal Clear used for?
Crystal Clear is a flushing and finishing solution that removes excess fertiliser salts, corrects nutrient lockout, and prepares plants for harvest while enhancing flavour, aroma, and colour.
Which growing media is Crystal Clear suitable for?
Crystal Clear is formulated for use in coco coir and peat-based soils.
Can Crystal Clear help with nutrient lockout?
Yes. Crystal Clear helps release bonded mineral salts from the growing media, allowing excess nutrients to be flushed away and improving nutrient availability.
Do I adjust the pH when using Crystal Clear?
No. Crystal Clear should be used without adjusting the pH. Fresh nutrient solution adjusted to pH 5.8–6.2 should be applied within 24 hours after maintenance or lockout flushing.
When should I use Crystal Clear before harvest?
Begin using Crystal Clear during the final seven days before harvest, applying it three times per week before finishing with plain water.
