Product description
Aptus Fulvic-Blast 1 L – low-molecular fulvic acid to get more out of every feed
A litre of Fulvic-Blast lasts a remarkably long time, because you only add a few millilitres once a week. For one or two home tents it is a bottle you buy once and keep using for a long series of runs.
What's inside
Aptus Fulvic-Blast is a liquid booster based on low-molecular-weight fulvic acid. Fulvic acid chelates nutrients, holding them in a form the plant can take up more easily, which helps prevent deficiencies and makes better use of your base feed. On top of that it contains plant boosters, L-amino acids and a broad range of micro-elements. It fits with any base nutrient, Aptus or otherwise.
How far 1 L goes
The dose is 3 ml per 10 L of nutrient solution, once a week, which works out at 0.3 ml/L. One bottle therefore treats about 3,300 L. If you mix a 100 L tank each week, that is 30 ml a week, so the litre lasts roughly 33 weeks of feeding.
Dosing small tanks
With a 10 or 20 L tank you need just 3 or 6 ml, so use a syringe for accuracy. Add it to the tank together with your normal feed once a week, from the start of the grow to the end of flower, and check EC and pH after mixing. It combines well with other Aptus products such as N-Boost, Super PK and Topbooster.
