Greenhouse Watering and Water Storage
Rainwater Storage Tanks
If you live in the country and rely on tank water you’ll understand the need to catch every precious drop Especially with a greenhouse full of plants, which require watering daily. The old ‘Water Butt’ is a great method for storing rainwater from the roof. It’s a fairly simple device, an old barrel or drum and a length of pipe or chain to let the water run down. Winter Gardenz greenhouses have a gutter system to aid in water collecting. Either way unless you have an endless supply of fresh water you’ll want to collect the rainwater for your plants.
Obviously the plants in your greenhouse won’t be watered with each rainfall as your outdoor plants will be, which can be good and bad. Good - you can control how often you water your plants and with what. You might decide to feed your plants nutrients, liquid fertilizer and the likes as a part of their routine watering cycle. Bad as you need to remember to water them every other day or set up some sort of automated watering system on a timer. I use a big black barrel in the greenhouse and fill that with water & nutrients once a week then water the plants with a watering can daily when I check my plants. The upside to this is that the barrel heats up and warms the water slightly which seedlings seam to prefer (as opposed to icy cold water in winter). Just be careful as it gets warm in there and the plants grow faster and become thirstier than you’d think so they do require quite a lot of water.
