BioBizz Top Max is an organic flowering stimulator designed to help plants get more from the bloom phase by supporting flower size, weight, nutrient uptake and final crop quality.
Built around humic and fulvic acids, Top Max helps make important minerals more available to the plant while supporting the natural processes involved in healthy flowering.
BioBizz also states that Top Max can help produce sweeter, smoother-tasting crops, making it a popular addition for growers who want to push more from their flowering programme without making feeding overly complicated.
Use it throughout flowering alongside Bio Grow and Bio Bloom, gradually increasing the dosage as plants move deeper into the bloom cycle.
Please note: the 10L BioBizz Top Max is purchased to order, so extended delivery or local collection times may apply.
Your base nutrients provide the core nutrition plants need during flowering, but a dedicated bloom stimulator can help them make better use of what's available.
BioBizz Top Max is designed to support the flowering process by helping free up and transport minerals such as calcium, iron and magnesium.
This supports plant metabolism during bloom while helping plants focus more effectively on flower and fruit development.
It is a straightforward way to add extra flowering support to a BioBizz programme without replacing your existing base nutrients.
The key ingredients behind Top Max are humic and fulvic acids.
BioBizz sources the humic acids from Leonardite, a naturally occurring material formed from ancient plant matter.
Fulvic acids are sourced from humate deposits and carry a natural electrical charge that helps attract minerals and nutrients within the growing medium and applied fertilisers.
Together, humic and fulvic acids help improve nutrient availability while supporting the plant's natural metabolic activity during flowering.
Top Max is designed specifically for use throughout bloom.
Start at a lower dosage during early flowering, then gradually increase the rate as plants develop and nutrient demand rises.
It works particularly well alongside Bio Grow and Bio Bloom, with Bio Grow continuing to provide the nutritional foundation and Bio Bloom supplying the additional phosphorus and potassium required during flowering.
BioBizz Top Max is suitable across a wide range of growing methods.
BioBizz recommends using Top Max at between 1–4ml per litre of water throughout the flowering period.
| Product | Flower 1 | Flower 2 | Flower 3 | Flower 4 | Flower 5 | Flower 6 | Flower 7 | Flower 8 |

| Top Max | 1ml/L | 2ml/L | 2ml/L | 3ml/L | 3ml/L | 4ml/L | 4ml/L | 1ml/L |
*Dosages are per litre of water. Follow the schedule that matches your growing medium and adjust according to plant response. After the final flowering week, follow the BioBizz schedule with plain water before harvest.
Top Max is a bloom stimulator, not a base nutrient.
For a complete BioBizz flowering programme, use it alongside Bio Grow and Bio Bloom.
Bio Grow continues to provide core nutrition and support for microbial activity, while Bio Bloom supplies the additional phosphorus and potassium required through flowering. Top Max then sits on top of that base programme to support nutrient availability and flowering performance.
If you want the easiest way to run a complete BioBizz programme, pair Top Max with our BioBizz Complete Soil Nutrient Kit.
The kit brings together the key BioBizz feeds, stimulators and additives needed from early growth through to flowering, including Top Max for dedicated bloom support.
It's a straightforward option for beginners or growers switching to BioBizz who want the full feeding programme without buying every bottle separately.
Please note: the 10L size is purchased to order and may have a longer lead time for delivery or collection.
Top Max works best as the finishing layer of a solid BioBizz feeding programme. Keep Bio Grow and Bio Bloom as your nutritional base, then increase Top Max gradually as flowering progresses instead of pushing a heavy dose from day one.
When do I use TopMax when flowering?
You would use BioBizz TopMax from week 2 of flowering until the week before harvest. It is designed to be used alongside your bloom nutrient.
do i use this with bio-bloom during the flowering stage,or do i stop using the bloom and use only topmax?
You would use Bio Bloom & Topmax together from the second week of flower until the final week before flushing.
