My temps in my greenhouse today is almost 90f with 34% humidity. Do I need to be concerned about the temp, maybe vent a bit more to get it down? Have one plant about 7 weeks old vegging in natural light. Thanks
No fan unless I go with a battery powered since I'm off grid. The greenhouse is small and temporary until the outside temps come up a bit, just A framed a few old windows and covered the sides with plastic. I have vents in the plastic to allow air exchange just with natural breezes and wind. I think my thermometer was in direct sunlight and getting a pumped up reading, temp was probably closer to 80 or just over. Of course it's measuring temp at ground level not plant height, that I need to change I know.
I would raise ur humidity. Also raise ur night time temp so the peak heat an peak cold stay within 15 degrees f of each other. Other than that, not much u can do. Maybe some b vitamins to keep the stress down If ur not using co2, u should consider it. It will actually help ur plants benefit from an extra 10 degrees of heat! lovin u (=
