If you're growing different varieties of plants in your greenhouse, you'll need to treat them differently as they'll all have individual needs. If your greenhouse is 2.5 x 2.5 metres, it won't take you long to check each variety and make sure it's getting what it needs. Often a watering can is the best tool as you can deliver exactly the right amount with it. If you're sowing seeds you'll have to be extra careful about watering as seeds can easily rot if the soil is too moist. Fogging is great for situations where you want high humidity i.e. if you're growing plants from humid places, or you have taken cuttings and they haven't rooted yet. However it won't deliver much water to the roots of the plants where they need it most.
Read our guidance on watering, which mentions micro-drip systems. An irrigation system is very useful for when you're away, but if you're on site then the best thing you can do is to assess the plants' needs daily, as the weather changes and water them as needed.
Enjoy your new greenhouse, it sounds lovely,
