on the other hand, What should I start with cold frame?

Start Seedlings Earlier

At least two weeks before you sow early vegetables like spinach, radishes or peas in spring, put your cold frame in place. This will help to gently warm the soil within the frame to temperatures that are more suited to growing cool-season vegetables.

also, How do you keep a cold frame warm at night? You can keep your cold frame warm at night by adding heat-absorbing materials, improving the frame’s insulation, and increasing sun exposure. Cold frames should always face south at a light angle to make the most out of the daytime sunlight.

How early can you plant in a cold frame?

If sowing directly into the cold frame, have it in place 2 weeks before seeding to warm the soil. If you start them inside and transfer them to the frame, you can start those 6 weeks earlier than normal.

What can I use instead of a cold frame?

Alternatives. As coldframes and mini-greenhouses can be costly to buy and make, many gardeners use ingenious makeshifts. All these are inexpensive and, if care is taken with ventilation, often prove good enough for most purposes.

Where is the best place to put a cold frame?

Place your cold frame somewhere sunny and sheltered, so plants and seedlings get as much light and warmth as possible.

What is the difference between a cold frame and greenhouse?

The biggest difference between a cold frame and a greenhouse is that a cold frame typically doesn’t use a heat source and might only stand a few feet tall; whereas a greenhouse is a tall structure that has heating and ventilation systems for a year-round controllable climate.
