Tower of Jewels Germination:
1) Fill treys with a mix of 50% Compost, 50% Sand.
2) Use a heated propagator to keep the temperature at 68-70 degrees F. 
3) At night, Drop the temperature to 35 degrees F. Temperature Fluctuation is Very Important or Germination will be slowed down tremendously. 
4) Use a grow lamp to give 18 hours of light as they need light to germinate.
5) Place the Seeds in the treys, "Slightly" covering with Very light layer of sand. Do not bury as they need light to germinate.
6) Use a spray bottle to mist them. Keep "slightly moist", Not wet.
7) Germination will occur between 2-4 weeks for most seeds as long as instructions are followed, but some can take up to a month or two, so don't toss out any that do not come up quickly.
