100pcs/Pack Fabric Seedling Starter Bags 8x10cm are perfect when you want to save money and start a lot of seeds. Fill the bags with with potting soil mix and pack into a tray or box with drainage holes (I use plastic milk cartons with top half cut back to the handle but leaving a 3 inch space uncut, where you can open the top to water and close it back to retain moisture. Put drainage holes in bottom of milk carton before packing with fabric pots.) These are biodegradable meaning you can plant them in your soil without disturbing roots. Size: 8x10cm (Different batches have slight variation in size) Package Includes:100 pcs *Seedling Raising Bags ** Please allow 2 to 4 weeks for delivery.
