Grower Notes Grow with 55 - 60° F nights and 60 - 70° F days. Pinch at transplanting. Obligate Long Day plant. Provide night interruption or day-length extension to force flowering under natural short days. Supplemental lighting during cloudy days has proven beneficial for flower production. For highest quality, bring in liners in fall to bulk for early spring sales.
