Not sure whether a new hydroponic nutrient additive deserves a permanent spot in your grow?
The Hydro Additive Taster Pack gives you four of our favourite hydro additives in one seriously good-value bundle, covering different stages and functions throughout the grow cycle.
Instead of committing to four separate products, you can put Bio Diesel Crystal Clear, House & Garden Top Booster, Plant Mechanics LED Fuel and Professor’s Nutrients Go Roots through their paces and see what works for your setup.
Normally $124 — yours this week for $85.
That’s a $39 saving on four additives selected to support your plants from root development through flowering and final-stage finishing.
Quantities are strictly limited. Once this week’s Taster Packs are sold out, they will not be restocked.
What’s Included in the Hydro Additive Taster Pack?
Professor’s Nutrients Go Roots – 100ml
Start where healthy plants start: at the roots.
Go Roots is a specialised root stimulator designed to encourage healthy root development and help establish a stronger root system, making it particularly useful during early growth and after transplanting.
House & Garden Top Booster – 250ml
Give flowering plants targeted support when they need it.
House & Garden Top Booster is a PK 13/14 flowering stimulator supplying phosphorus and potassium to support flower and fruit formation during the bloom cycle.
Plant Mechanics LED Fuel – 1L
A late-flower additive built with quality-focused growers in mind.
LED Fuel is formulated to help plants make better use of available light while supporting trichome development, aroma, flavour and colour. It is particularly suited to high-intensity LED and full-spectrum lighting environments and is recommended during the final stages of flowering.
Bio Diesel Crystal Clear – 250ml
Finish the cycle by helping clear accumulated mineral salts.
Crystal Clear is a specialised flushing agent designed for coco fibre and peat-based growing media, helping release excess fertiliser salts and clear nutrient pathways during final flushing or when correcting nutrient build-up.
Four Additives. Different Jobs. One Easy Way to Try Them.
The point of this bundle isn’t to give you four bottles that all do the same thing. Each product has a different role:
-
Go Roots: Supports early root development and establishment.
-
Top Booster: Provides targeted PK support during flowering.
-
LED Fuel: Supports late-flower trichome, aroma, flavour and colour development.
-
Crystal Clear: Helps manage accumulated fertiliser salts and supports final-stage flushing in suitable media.
That means you get the opportunity to experiment with additives across multiple stages of your grow before deciding which ones earn a place in your regular nutrient program.

Strictly Limited Weekly Deal
This is a Deals of the Week bundle with limited stock allocated specifically to the promotion. Once it’s gone, it’s gone — this bundle will not be restocked.
Who Is This Bundle For?
- Hydroponic growers who want to experiment with new nutrient additives without buying multiple larger bottles
- Growers building or refining their hydroponic feeding program
- Customers looking for additives suited to different stages of the plant cycle
- Growers using hydroponic, coco or compatible growing systems
- Anyone wanting to compare how different additives perform in their own setup
- Growers looking for better value when trying new hydroponic additives
How to Use
Each additive has its own recommended application rate, growing-stage timing and compatibility requirements.
For best results, follow the individual product directions on each bottle rather than adding all four products together at once. Monitor your nutrient strength, pH and plant response whenever introducing a new additive to an existing feeding program.
Frequently Asked Questions
Do I use all four additives at the same time?
No. These products are designed for different purposes and stages of the grow. Follow the individual directions for each product and introduce additives according to your existing nutrient program.
Is this suitable for hydroponic growing?
The pack has been assembled around hydroponic nutrient and additive applications. Individual product compatibility varies by growing medium and system, so always check the directions before use.
Is Crystal Clear suitable for every hydroponic system?
Crystal Clear is specifically formulated for coco fibre and peat-based growing media, so growers using other systems should check its suitability before application.
When should I use LED Fuel?
LED Fuel is intended primarily for the later flowering period and is formulated to complement high-intensity and full-spectrum lighting environments.
What does Top Booster do?
Top Booster supplies a PK 13/14 blend designed to support flower and fruit development during the flowering stage.
What is Go Roots used for?
Go Roots is designed to encourage root development and is especially relevant during early establishment and after transplanting.
Will this bundle be available again after it sells out?
No. Stock for this promotional bundle is strictly limited. Once the available Hydro Additive Taster Packs sell out, they will not be restocked as part of this deal.
