@rocketman...I don't use any artificial lights. Daylight without direct sunlight

This my first time evere growing cacti

I got the seeds from Free Spore Ring Europe for 1E...it said that the baggie contains 50+ seeds..I took the time and counted them all..it was 550...hahahah...kept 100 and gave away the rest. Ratio of sprouting was close to 60%.
Also they (FSRE) are very careful from where and who they recieve seeds. I'm sure it's Peruvian but it didn't said anything about "sub-strain".
Have another 30 of them waiting to get transplanted..should have done it earlier but I was lazy
Peace
