Hello jsalramos, we are in the same area, and I grow my Crassulas outdoors. I just use cacti mix with added pumice and top dress my containers with chicken grit. Make sure you use containers with drainage holes, not too deep containers, their root system is rather shallow, so that when it rains, as is happening these past few days, they can just easily drain. At times we also get tule fog conditions/reverse cold inversion, so it really becomes imperative for the soil to be able to drain well. They can take temps in the low to mid 30F's but ideally kept dry. So during winter time, I try to monitor if we happen to have any frost advisories or temps in the low 20F's. This winter was not bad at all compared to previous years, so just observe the temperatures closely.
Crassulas love our winter conditions, even if it rains, but you got to make sure there is good drainage in your container and your soil mix is gritty and airy at root zone. I just allow Mother Nature to do the watering here during winter to early Spring, then when our onerous long and dry conditions returns, you can water thoroughly at least once a week. Our humidity levels are so low here, especially as we start to go into dry weather, so it is not too worrisome to get the soil to dry.
Although they can take direct sun, morning sun is best, with our very dry heat, it also helps to position them in some shade during the long dry afternoons especially when it starts hitting 90F and higher. Most of my succulents, slow down in growth when temps soar too dry and too high, then they perk up again with new growth once the temps returns to a more tolerable range of 75F to 85F. My Crassulas are usually in bloom during late winter to early Spring and really enjoys as much sun as it can at this time of the year which actually coincides with our city trees still dormant they are able to get more light, then they get dappled shade from the trees when summer comes around.
