How to use Bio Green - Hydro A+B

Bio Green - Hydro A+B is most suited for sterilized systems that use peroxides whereas Bio 1 & 2 are biological and cannot be used alongside tank sterilizers.

Use in conjunction with the rest of the bio green range according to the feed schedule

Hydro A and B are used from the start until the end of the growth according to the grow schedule. In the final phase an additional bloom stimulator (like bio green PK) is recommended.

When 2 mixing tanks are used mix Hydro B in the B tank, when 1 mixing tank is used mix Hydro A and Hydro B together in enough water.

Do not leave the prepared water. Preferably use water at room temperature. Water every day as needed. Be careful not to overdose.
