Aptus Topbooster 500 ml – flowering and ripening stimulator for better flavour and quality
You've seen what Topbooster does and you want it in every flowering run, across one or two tents. The 500 ml bottle is the practical step up. Aptus Topbooster is an organic stimulator that kicks off the flowering response, supports smooth transitions between growth stages and gives you more flower sites with better flavour, appearance and overall quality.
Why growers use it
It brings extra energy in bloom through L-amino acids and sugars (polysaccharides), plus boron, iron and molybdenum, natural bloom-promoting plant stimulants and vitamin complexes from fermentation. It's an additive, so it works next to any base NPK nutrient without changing your schedule.
2,500 litres per bottle
At 2 ml per 10 L, 500 ml treats about 2,500 litres of nutrient solution. Experienced growers who move up to 4 ml per 10 L during the cycle still get some 1,250 litres out of it. With a 50 L reservoir at the standard dose, you're looking at 50 tank fills.
Good to know
Because Topbooster is organic, don't leave it in the reservoir for longer than 2–3 days. Size your mixes so a tank is used up within that time, or top up with fresh solution. Running drippers? Use Aptus System-Clean to keep the lines clear.
