RI Grows Mailer - Light Pollution
Myth: Extra light bothering neighbors
RI Grows: Blackout screens to capture over 99% of light
Keeping curtains like these completely closed cause problems with heat and humidity.
One solution is “gapping,” or opening the curtain a small amount (5% to 10%) to vent the heat and humidity. Most rules, such as those that have been in effect in the Netherlands for a decade, allow a few hours of gapping during the night. Leamington’s new bylaw allows for 10% gapping between 2:00 and 6:00 a.m., however, the Kingsville bylaw, unfortunately, doesn’t allow any gapping. The photo shows two Dutch greenhouses—one with the light-abatement curtains fully closed, and one with a curtain gapped open 10%. The fabric used is Svensson’s Obscura.
Will RI Grows support a “Dark Sky” ordinance requiring curtains to be fully closed? Who will enforce compliance? Simply having the curtains does not ensure that they will be used.
