Biobizz Top·Max is an organic flowering booster designed to improve flower size, aroma, flavour and overall finish during bloom.
Built around humic and fulvic acids, it helps plants move and use nutrients more efficiently during flowering, supporting bigger, denser flowers and a sweeter final result.
If you want to get more out of your bloom feed without overcomplicating things, Top·Max is one of the easiest upgrades you can make.
Please Note: The 10L bottle is purchased to order, so extended delivery times will apply.
Flowering plants need more than just base nutrients if you want the best possible finish. Top·Max is designed to support nutrient transport and floral development during bloom, helping plants put more energy into size, density and final quality.
It’s especially useful if you want flowers with a stronger smell, better taste and a fuller finish by harvest.
Use Top·Max throughout the full flowering phase.
Mix into your feed water and use alongside your regular flowering nutrients.

Top·Max uses humic and fulvic acids derived from leonardite to help free up and transport nutrients more efficiently during flowering.
That means plants can make better use of available nutrition while focusing on flower production, helping improve both yield and final quality.
Start low early in flower and push harder later on. Top·Max is most useful when layered on top of a solid bloom feed rather than used on its own.
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.
