FINISH PGRs

TECH TIPS

Cool days with high light will reduce the need to apply PGRs.

If needed to control height, spray with B-Nine ® WSG at 2,500–5,000 ppm, A-Rest ® at 3–7 ppm, Bonzi ® at 10–30 ppm or Sumagic ® at 5–10 ppm.

FINISH PGRs

TECH TIPS

It is very important to spray the plugs with Cycocel ® at 300 ppm about 10 days after sowing to help reduce hypocotyl stretch. Shorter hypocotyls will result in a stronger central stem after transplant and will reduce floppiness in the finished plant.

If grown cool and under high light, PGRs will not be necessary. Under suboptimal conditions spray with B-Nine ® WSG at 2,500–5,000 ppm or Cycocel ® at 750–1,000 ppm as needed.

TECH TIPS

Usually not required if growing cool. If conditions are warmer or darker than ideal spray with B-Nine ® at 2,500–5,000 ppm.

Keep media pH below 5.8 to help avoid Thielaviopsis infections. Under hot temperatures provide lower light levels to reduce heat stress. Do not hold Pansy plugs - transplant before plugs get root bound.
