Product description
Aptus Startbooster 1 L – root and growth stimulator for every veg phase
Once Startbooster is a fixed part of your schedule, the litre bottle is the practical choice. It covers veg in several cycles and costs less per litre than the 250 and 500 ml bottles.
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.
How much water 1 L treats
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. One litre therefore treats about 4,000 L of water. For a 100 L tank you need 25 ml per fill.
In practice
Plan around the short shelf life of the mix, not of the bottle: once diluted, use it within 2–3 days. With a large tank, mix a smaller batch more often rather than one big batch for the week. Rooting clones? Use 1 ml per litre; at transplanting, give a dip of 10 ml per litre. In drip systems, run Aptus System-Clean alongside to keep lines free.
