Aptus Startbooster 5 L – root stimulator in bulk for grow rooms
Large clone runs, mother plants and a grow room full of young plants in veg: at that scale the 5 L can makes sense. It has the lowest price per litre of all Startbooster sizes.
Scale: about 20,000 L
The base dose is 2.5 ml per 10 L in veg and the first week of flower, added after your NPK and after checking EC. The 5 L can covers around 20,000 L of water. A 500 L tank takes 125 ml per fill.
What it does
Aptus describes Startbooster as a 100% biological root and growth stimulator. It combines organic nitrogen chelated with L-amino acids, microlife biomass from controlled fermentation, humic acid from Leonardite and fulvic acid. Together they push root and root-hair development, condition the medium and supply bioavailable nutrition in veg. On pre-fertilised soil you can even skip an extra grow feed.
Working at volume
With tanks this size, a dosing pump saves you from measuring small amounts by hand. Because the diluted mix should be used within 2–3 days, size your batches to what you water in that window. Drip lines need Aptus System-Clean to stay free.
Storage
Keep the can tightly closed, cool and out of the light. Decant a litre into a smaller bottle for daily use so the bulk stock stays sealed.
