SuffOil-X rates range from 1 – 2% v/v (volume to volume) with lower rates used for dipping cuttings or potted plug foliage. The maximum labeled rate is 2%. It is recommended to use the 1% rate for any indoor or greenhouse-grown crops. While there is no restriction on how long the mixed solution can be stored, we recommend using the solution within 24 hours after vigorous agitation.
