Sunny weather all day in our area, with current temperature at 50 F° and should reach 55 F° later.
- Rolled up the garage door (south facing)
- Removed the Double Reflective Insulation and
- Replaced it with a 6 mm plastic sheet (no UV inhibitors / filter)
Although lights and heater are off, temperature inside the grow room shut up to 74 F°, within 30 minutes.
In about an hour, I will roll down the garage door half way to let in indirect sunlight only and keep the leaves from burning.
Hybrid Grow Room will allow gradual hardening without the need to do any shuffling.
