FINISH PGRs
TECH TIPS
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.
FlashForward is a genetically compact Petunia so will need less PGRs than other Petunias. It is best to be proactive in applying PGRs on Petunias. Anticipate changes in weather or other conditions that can cause plant stretch and apply PGRs before plant stretch begins. FlashForward Petunias respond well to B-Nine ® WSG sprays at 1,500–2,500 ppm. Do not apply B-Nine ® WSG after bud formation or flowers may reduce in size and/or become distorted. Bonzi ® drenches at 0.5–1.0 ppm during later stages in the crop will reduce stretch and will not affect flowering as much as B-Nine ® WSG.

FINISH PGRs
TECH TIPS
PGRs are usually not necessary under proper (cool with high light) growing conditions. If needed due to low light and/or high temperatures, sprays of Bonzi ® at 15–20 ppm or B-Nine ® WSG at 5,000 ppm are effective. The best time to apply PGRs is about two weeks after transplant; later treatments will give more height control but will delay flowering. Popstars also respond well to a negative DIF.
Keep EC lees than 0.75 mS/cm as Phlox drummondii are sensitive to high salts. For this reason, do not try and control growth by growing the plugs dry as well.

TECH TIPS
Grow plugs on the dry side to avoid excessive algae growth.
If grown at the recommended temperatures, PGR applications should not be necessary. If needed, sprays of B-Nine ® WSG at 2,500–5,000 ppm are effective in helping control leaf size.
