Among many, gardening is a true passion in life. The only problem is, it is a passion that can generally only be sated as the weather permits. Once the winter months set in, the party is pretty much over until the following spring. Thankfully, that doesn't have to be the case if you happen to be one of those fortunate gardeners who has access to a greenhouse. Then, with just a little work and preparation, your love of gardening can last you the whole year through.
Make walking through the greenhouse a part of your daily routine. Set up paths of ample width throughout the greenhouse and make sure that you walk these paths everyday. Because of the atmosphere in the greenhouse, things can change with your garden very quickly, so it is important to stay on top of it so that problems can be addresses and resolved as they arise.
Monitor the temperature. As a general rule, the optimal temperature for most plants is about 80 degrees Fahrenheit. Stray to far in either direction from this temperature and your plants will begin to underperform at best--and potentially start to die at worst. To deal with too much heat, simply open the doors for a bit to allow the release of some of the greenhouse gasses. For the cold, the installation of additional insulation might be needed, or even the placement of space heaters.
Check for air flow. Though it might sound funny, plants need air to live just like we do. If your greenhouse it too airtight, the air will become stale and the plants will suffer. This can be alleviated by leaving small gaps under the doors when constructing the greenhouse or installing a ventilation system.
Set up your gardening flats off the ground. Not only will this help with properly irrigating that plants, but it will also make them much more easily accessible and make working with them less likely to leave you with a sore back. The flats can be supported on tables or cinder blocks or even 55-gallon drums.
Keep the soil moist. You want the soil in your garden flats to be damp, but not soggy. Overwatering will cause the seeds to simply float up to the surface and prevent them from taking root.
