SEED FINISHING
FINISH PGRs
TECH TIPS
If grown in smaller containers or under suboptimal conditions, sprays of B-Nine ® WSG at 2,500 ppm are effective at reducing stem length and leaf size. Do not spray after buds have started to show color or flower size will be reduced.
Bright Sparks is a facultative short day variety and will flower faster under short days. If sowing under short days, it is vital to grow the plugs under a day length of at least 14 hours to promote sufficient vegetative growth before flowering.
FINISH PGRs
TECH TIPS
PGRs are necessary to control plant height and create a fuller plant. Recommended are three sprays of Bonzi ® at 25 ppm or B-Nine ® WSG at 5,000 ppm applied 7-10 days apart, beginning two weeks after transplant. B-Nine ® WSG may delay flowering by 4-7 days. A Bonzi ® drench at 2-4 ppm when the plant has reached the desired height will help prevent stretch at retail.
A 15 °F positive DIF is recommended for best germination results. Cleome is a heavy feeder; start feeding in the plug about two weeks after sowing.
FINISH PGRs
TECH TIPS
Cosmos will flower early under short days, so to allow bulking of the plug provide a 14 hour day length during propagating.
Containers 1 pint and larger, PGRs are usually not necessary. If needed, for pack production spray with B-Nine ® WSG at 2,500 to 5,000 ppm to help control plant height.
FINISH PGRs
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.

TECH TIPS
If needed, spray with B-Nine ® WSG at 2,500-5,000 ppm.
Provide day extension lighting to 12– 14 hours/day to help prevent premature flower bud set.

If needed, spray with B-Nine ® WSG at 2,500-5,000 ppm.
Provide day extension lighting to 12-14 hours/day to help prevent premature flower bud set.
FINISH PGRs
TECH TIPS
If needed, spray with Bonzi ® at 5-8 ppm.
Providing high light and dropping the temperature to an ADT of 60 °F (21 °C) will reduce the need for PGRs. Day extension lighting to 14 hours will hasten flowering of the finished plant.
