TECH TIPS

To control growth, apply one or two applications of Bonzi ® either as a spray at 20–40 ppm or as a drench at 0.5–1.0 ppm.

Only the first application of plant growth regulators (PGR) is necessary for the plug. After two weeks, you can alternate moisture between 2 and 4 to help tone the plugs. Provide supplemental lighting if possible if DLI is lees than 8 mols/day.
