Greenhouse Gardening Tips
It's tempting to think that once a greenhouse is built, it will take care of itself. The glass or plastic walls trap sunlight and heat, so the environment inside should just naturally stay warm and comfortable, right?
Not quite. That same trapped heat is exactly why greenhouses can swing from too cold at night to dangerously hot by early afternoon, sometimes within the same day. REED COMPLETE GUIDE
Greenhouse Ventilation
Most people assume a greenhouse gets hot because the outside air is hot. That's only part of the story, and it's the smaller part. The real driver is solar heat gain: sunlight passes through the glazing (whether that's glass, polycarbonate,
or plastic film), strikes the plants, soil, and hard surfaces inside, and converts to heat. That heat then radiates back outward as thermal energy, but the glazing material blocks most of it from escaping. According to the University of Georgia Cooperative Extension, REED COMPLETE GUIDE
Greenhouse Soil
A greenhouse doesn't offer that pause. Because the structure protects plants from frost and extends your growing window, the same bed can produce two, three, or more harvests in a single year. Every one of those harvests pulls nitrogen,
phosphorus, potassium, and trace minerals out of the soil and without a rest period, there's no natural mechanism putting them back.. REED COMPLETE GUIDE
Frequently Asked Questions
1, What temperature should a greenhouse be kept at?
It depends on what you're growing. Cool-season crops do best between 50°F and 70°F during the day and 45°F to 55°F at night. Warm-season crops need 60°F to 85°F during the day,
2, What size fan do I need for my greenhouse?
A commonly used starting point is to multiply your greenhouse's floor area by 8 to get an approximate target in cubic feet per minute
3, How often should I test my greenhouse soil?
Once or twice a year is a reasonable general practice for most home greenhouse gardeners. This is a widely used rule of thumb rather than a figure backed by a specific research study,
4, What's the ideal soil pH for greenhouse vegetables?
Most vegetable crops grow best with a pH between roughly 5.8 and 6.8, based on guidance from the University of New Hampshire Extension and Clemson University Cooperative Extension.
5, What are the most common greenhouse pests?
The pests home greenhouse growers run into most often are aphids, whiteflies, spider mites, fungus gnats, and thrips. Aphids and fungus gnats tend to show up first for most new growers,
6, What size fan do I need for my greenhouse?
A reasonable starting point, based on University of Massachusetts Extension guidance, is fan capacity of roughly twice your greenhouse's floor area, measured in CFM.
