Aptus Startbooster 250 ml – root and growth stimulator to get started
Starting seedlings or a first batch of clones and want to see what a root stimulator does? The 250 ml bottle is the low-risk way in: enough for a small tent, without a big outlay.
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 far 250 ml goes
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. That means 250 ml treats roughly 1,000 L of water. Rooting clones at 1 ml per litre, it makes about 250 L of clone solution.
Measuring tip
At 2.5 ml per 10 L the amounts are tiny, so use a 5 ml syringe rather than the cap. For a single 5 L watering can that's just 1.25 ml. Don't leave the mix in a reservoir for more than 2–3 days.
