This is a grow box for herbaceous plants seedlings and clonal cuttings. It consists of a foil-lined cardboard box with doors cut from the flaps, ventilation holes covered in lengthwise-halved toilet paper rolls, and a mounted ceramic lamp socket inside. It uses a Philips 10-Watt BR30 Daylight (5000K) LED Flood Light Bulb, which, being high in blue light, is good for sprouting and root formation. Four rosemary cuttings are pictured, planted in Miracle-Gro Seed Starting Potting Mix and potted in Jiffy Square Peat Pots.
