Know before you buy
Finaleboost is specifically formulated for the final ripening and bulking stages of your plants. You should begin application during the later weeks of the flowering cycle, specifically starting around week 5.
While many bloom boosters provide high levels of potassium, they can often interfere with the uptake of other essential nutrients. Finaleboost is engineered to manage mineral antagonism, ensuring that your plants can still effectively absorb nitrogen, calcium, and magnesium even while receiving a potassium boost.
The application rate increases as your plants approach harvest. Use 6 ml per 5 gallons of water during week 5 of flowering, increasing to 20 ml per 5 gallons by week 8.
Finaleboost is a mineral-based liquid concentrate designed for soil drench application. It is best suited for flowering plants grown in soil-based environments.
Yes, by providing precise potassium control and preventing nutrient lockout, Finaleboost helps the plant focus energy on fruit and flower development. This leads to more robust growth and improved overall harvest quality.
