FINISH PGRs
TECH TIPS
Warm day temperatures can promote soft growth and excessive stem elongation.
Partybells Penstemon, if grown cool will likely not require PGR applications. However, if needed, spray applications of Bonzi ® at 10–15 ppm or Sumagic ® at 5 ppm are effective in controlling stem elongation.

FINISH PGRs
TECH TIPS
BeeBrigh Pentas are genetically compact, and typically do not require PGR applications. If needed, the following PGRs are effective as sprays: B-Nine ® WSG at 2,500–5,000 ppm, Cycocel ® at 750–1,000 ppm, Bonzi ® at 5–10 ppm, or A-Rest ® at 3–5 ppm.
Provide supplemental lighting when DLI is less than 12 mols/day. Monitor pH and maintain above 6.1, or growth can stall.

FINISH PGRs
TECH TIPS
Duvet is a genetically compact Petunia so requires significantly less PGRs than standard Petunias. It is best to control growth by providing optimal growing conditions. Suboptimal growing conditons (too warm, too humid, overwatering, low light) can promote soft, stretchy growth. If growth control is necessary, Duvet responds well to sprays of B-Nine ® WSG at 2,500–3,500 ppm or Bonzi ® at 5–15 ppm.Bonzi ® drenches are not recommended.
Covering seed is not necessary but a light vermiculite coating will help maintain moisture levels in drier climates. Keep pelleted seed at moisture level 5 the first several days to help dissolve the pellet. Providing long days in the plug stage will reduce overall time to flower. Low boron levels can induce tip abortion. Spraying an uneven plug tray with B-Nine ® WSG at 1,500 ppm may help even the growth in the tray.
