Nojic fits perfectly into Socker and Ackerbär Greenhouses (both also from IKEA), which makes them perfect for growing plants from seeds. I needed something to prick my Saraccenia seedlings in, so I created this dividers. Each square gives them about 3,5x3,5cm (1.3x1.3inch) space to grow. Saraccenia enjoy wet feed, so the lack of drainage is no problem for them, but keep in mind that not all plants tolerate that. 

For one set you need 4 short and 3 long pieces
