Our growth promoter spray contains a blend of beneficial bacterial microorganisms which increase yields, promotes healthy growth and prevents the infamous Trichoderma (Trich for short).

This is perfect for anyone having issues with contamination as the microorganisms fight off the dreaded trich. When using our Growth Promoter Spray we have seen around a 30% increase in yields as well as faster pinning; around 3 days before our untreated batch.

Works on coco coir, manure, straw, masters mix and many other substrates.

How to use

  • Shake bottle
  • Apply 5-10 pumps per 1L of bulk substrate when spawning-to-bulk
  • Mist every 2 days thereafter
