Greenhouse Runs Under Glass

[justicebzwieg]

Greenhouses sit between indoor and outdoor growing, and photoperiod feminized plants handle them well. The glass keeps autumn rain off the flowers and adds a few weeks at both ends of the season, but it also traps humidity overnight unless the vents and a fan work. Growing under glass is mentioned at https://queenfeminizedseeds.com as a third option beside tents and open ground, with flowering still triggered by the natural shortening of days. Cheap polytunnels run hot at midday, so shade cloth is often needed more than heating.
