Grow Greenhouse, designed by Caroline Wetterling for Design House Stockholm. Grow is a greenhouse for nature's smallest flowers and a nursery for the plant's first stages of life. Grow is made of two glass parts. The bottom part holds the soil and the plant. The top part is a lid equipped with a spout, allowing it to be used as a watering can. It also functions as a valve that lets in air and regulates the moisture and temperature levels inside the greenhouse. Grow is made of hand-made glass. Available in three sizes.
