Did not want to communicate that I am unhappy with the size of the cactus - they are healthy and I have cared for the mammillarias for 3 years, the middle two I just recently purchased. I'm always striving to make sure the cactus are well cared for, and wanted to see if a grow lamp would help them be the best and healthiest they can be!
To me it looks like you are doing a good job. I'm not seeing any deficiency in the Mamms after 3 years under your care (assuming you haven't changed locations during that time). I'd love to have your window situation in the winter months, but not when the summer sun would be blasting it. Different locations always have to have some kind of work around for plants depending the specific conditions a grower has to work with. I usually try to discourage active growth in the winter months for most of my plants. The Mamms just seem to like the borderline weather between freezing and late summer. Depending on the winter weather they tend to be at their best if I can manage to handle the usually brief spells of freezing temps. They really don't come indoors much. True for the cacti I have growing. The outdoor light keeps them happy, so I just have to watch for temperature drops.
