Summarize this article:

You can use any size jar, though keep in mind the number of Scobys you want to store in it. Wash your jar thoroughly with soap and water. You can squirt some soap into the jar and soak it, then rinse the jar to wash away soap residue. For example, you can use a a 0.5USgal (1.9L) glass jar. Over time, you will add more Scobys into the same jar to create your "hotel." This is helpful in case 1 of your brews goes bad. That way, you will have back up Scobys to use for new batches. You can place a few Scobys or several inside the same jar. You can use some of your recent kombucha brew or use a bottle of store bought kombucha. Pour in some kombucha, and then dump in a few cups of freshly brewed green or black tea mixture. This helps feed your Scobys in their hotel. To make your tea, you can boil {{convert|5-6|cup|L} of water and steep about 4 teabags. Then, pour in about 0.5 cups (0.12L) of cane sugar. Use a tightly woven cloth, and place it on the top of your jar. Then, screw on your lid so it fits tightly over your jar. If you don't have a cloth, you can use 2 coffee filters instead. You can place this next to other kombucha batches, if you'd like. Make sure your Scoby hotel will not be disturbed in whatever location you pick. Since you have multiple Scobys in your batch, it will ferment quicker than normal and will be much more potent. Because of this, replace your kombucha with a fresh batch after 2 weeks. To use up your kombucha, you can drink kombucha from the jar, pour some off, or discard it.

Summary:
Select a large, sterile glass container big enough to fit several Scobys. Put all of your Scobys into the jar. Pour in 1 cup (0.24L) of kombucha and 3 cups (0.71L) of freshly brewed tea. Cover your jar with a clean cloth and secure it with a lid. Store your jar in a dark, warm, and dry place. Replace the kombucha in your Scoby hotel every 2 weeks.
