This metal soil cube press wasn't cheap, but has made many starter cubes and is still in good condition.

The mixture should be light, seedling mixes are a good choice. My current favorite is a 50-50 mix of Just Right Xtra and Just Right Lite. Add enough water to make a doughlike consistancy, and let set for 1-2 hours. The mix should be able to be pressed into balls and somewhat hold their shape.

The press is well filled with potting mix. The form is set into place, and the piston holds the cube in place while the form is removed.

Allow the cubes to dry and they will firm up. However, they will always be a bit fragile, and are much easier to break than commercially made cubes.

Nanodome Mini Greenhouse

These cool little kits from Future Harvest are great for starts and cuttings.

The Nanodome Mini Greenhouse comes with a T5 light that sits in a trough on the top of the dome. The extra strength 1020 tray on the bottom is a substantial improvement over average 1020 trays.

I’ve had good luck with Rapid Rooters from General Hydroponics. They are used to start seeds or cuttings. If they dry out before use, you can re-wet them.

They work well as long as they are kept moist, but not soggy.

Rapid Rooters are single use.
