  • Use a grow light, if the weather stays cloudy for too many days. Most structures have enough room for these.
  • Do not open the lid or door on your structure more than necessary. This will let your natural heating out of the greenhouse where you need it to be.
  • Don't be afraid to experiment with plants. Some early spring crops and flowers may also grow well in your structure.
  • Set a budget for how much you can afford to spend on your cold greenhouse, as some can be a bit pricey. If you spend too much on the structure, you may not have as much to spend on the plants you want to grow.
  • It is often handy to situate the cold greenhouse near where your dryer vent exits the house. If the weather in your area gets really cold, this will heat the interior of the cold greenhouse to ensure that the plants don't suffer during a short term extra cold snap.
  • Remember to plant enough plants to create heat within the greenhouse. Plants make heat.
