Tatyana,
Hello new member, here's your first acorn. Seeds are some times the hardest to do. Some are like weeds and can't stop them, other seem to never come up. I never tried echeveria due to price is reasonable and very hard to tell apart so I buy them in the big box stores at very low cost. And labeled' Most under $3. Also having friends that give me starters to grow my own. Plants that I have a hard time getting or is very expensive well that is another mater. I like to cross-breed and make my own hybrids so it must be done growing seeds. Seeds (mostly all) needs bottom heat to help sprout (warm) and some light which fluorescent bulbs work excellently due to low heat to not burn the new sprouts. They need hi moisture but dry feet. I do this by using take home containers with the clear plastic lids with black bottoms. Keep the soil just a little moist and keep covered until the seeds start to germinate (sprout). I continue to keep covered due to more seeds just about to germinate and to make sure I can get all that I can get. Leaving the cover on for a month or so should not be problem. You can start by leaving it unsealed and up an inch for a while, note; at this time water misting is a must. Too much, rot, too little they dry up and die. Once they fall over and dry up, nothing can bring them back. Time to start over. So you see, it is kind of hard. Check out Adams' seed thread. Also most importantly, who you purchased your seeds from. One seller on Ebay, almost never got a seed to germinate. Another 'Exotic_cactus_collection' almost always gave me excellect results. Checking back to them with feedback and some times they will refund or replace your order. Take pictures and show us what your doing. We all learn and enjoy here. Bust of luck. Stush
