Why we Love It
There's a lot to love about Biobizz. It works with the microbes in your media to enhance growth organically.
100% Organic
Biobizz holds 7 different organic certifications worldwide
No pH Up/Down Needed
No pH Up or Down is needed when you use this range as soil acts as a natural buffer
Quality Boosting
By enhancing growth naturally, you're bringing out the natural flavour and aroma of fruit and flowers, rather than altering it.
Hand crafted
Nutrients are handcrafted in small batches to ensure the quality is consistently good.
Dutch Roots
Holland's the greenhouse capital of the world. You know Biobizz is good - it's now sold in 64 countries worldwide.
Versatile
You don't have to use the entire range at once or stick to organics. TopMax, Bio-Heaven, Bio-Bloom & Root Juice can all be used in hydro systems alongside other nutrient ranges.
Biobizz Bio-Grow
It's a carbohydrate that feeds plants and the microbes in your media, from start to flush.
You don't swap it out for a flowering booster in bloom. Instead, you continue to use it alongside Bio-Bloom until flush.
- Enhances photosynthesis & growth (high in Nitrogen, potassium & Betaine)
- Improves taste & aroma in flowering
- Nourishes beneficial bacterial flora in media
- Vitamin rich with 70+ trace elements
- NPK: 4-3-6

Biobizz Bio-Bloom
To ramp up flowering, use Bio-Bloom alongside Bio-Grow in when you flip to flowering.
It's been proven to increase the number of flowering sites and improve fruit & flower formation. Bio-Bloom is rich in Phosphorus & Potassium, so you can use it as a PK booster.
- Get extra flowering sites
- Accelerate flowering
- Acts as strong PK booster (rich in Potassium & Phosphorus)
- Lasts in tank 2 -3 days
- NPK: 2-7-4

Biobizz Alg-A-Mic
It's a stress-reliever and growth promoter.
- Helps correct overfertilisation
- Aids transplanting, training & pruning
- Improves tolerance to extreme hot & cold temperatures
- Suitable for root drenching & foliar feeding
- Handcrafted & 100% organic

Biobizz Root Juice
It's a root booster. To promote root development and root health, Root Juice also stimulates bacterial life in your rootzone
Use it to prevent root diseases, root burning & overfeeding. You'll also get a denser root ball.
- Increase root development
- Prevents root burning, root disease & overfeeding
- For pre-soaking cubes & propagation

Biobizz Bio-Heaven
Bio-Heaven is a bio-stimulator that improves nutrient uptake & translocation. It's packed with L-amino chelates, derived from organic soy beans. Use it as a root feed or foliar spray, in any growing system. It really maximises the rest of your feed and ultimately increases yield.
- Improves uptake of minerals & trace elements (from 20-35% - to as high as 95%!)
- Boost plants' metabolisms
- Accelerates flowering

Biobizz TopMax
TopMax is a BRIX (natural sugars) booster, designed to boost flower production. It contains fluvic acid & a touch of humic. This brilliant mix helps plants uptake & translocate trace elements.
It also accelerates cell division, so you get more fruit and flowers that are bigger, heavier and better quality.
- Increases BRIX levels (natural sugars)
- Enhances aroma, density & flavour
- Contains ethically sourced fulvic & humic acids (from Leonardite)

Biobizz Leaf-Coat
Biobizz Feed Charts
- Start using fertilisers when your plant is 10-15cm or has 2-4 leaves.
- In soil, use just water every 3rd watering or once a week to prevent overfertilisation.
- You can mix several fertilisers in the same feeding water.

NOTE: The above feedcharts are guides only.
If unsure of your dilution rate, start low then gradually build up your nutrient strength over time. Look for signals from your plant as to whether more or less feed is required. Environmental conditions such as temperature and humidity should also be taken into consideration.
