The Plant Tender,
During the second month of growing indoors, bring the number of hours of light down to 16 or 17, so that the plants don’t start flowering when they are placed outdoors. They receive about 15.5 hours of light outside in late June. Indica, Indica hybrid, and other early-season plants are most likely to bolt. Sativas are not likely to start flowering early.
The plants may have other problems adjusting to the outdoors. They have been growing under low light conditions of fluorescents as compared to sunlight, so they are likely to get burned by the sun’s intensity and UV light. Let the plants adjust by placing them in the shade to begin with, then giving them brighter light over a week-long period.
