Hi I am hoping for some insight regarding growing cacti from seed. My boyfriend gave me a mini greenhouse (plastic egg, soil, and seeds) kit a few weeks ago and I followed the instructions however I think I used too much water and it looked like it was starting to mold (cobweb looking strings?). So in doing some research I found that this was commonly possible and the only way for the plants to survive was to repot. I bought some cacti soil from Home Depot, fertilizer, and a small pot. Did my best to transfer the tiny guys but... they all died. SO... I bought a new kit online and want to try again since I already have all the supplies and my bf was disappointed that I killed the first ones. I will definitely water less but I am mainly wondering how long to keep them in the plastic egg before transfering them. Do I take the lid off at some point? They were pretty small when I transfered them to the pot the first time and I don't think they were strong enough to survive. Any insight or advice is welcome. Keep in mind I am new to this and I know my past attempt wasn't the greatest. Thanks!
