Do G. pulchra grow THAT slow?

[SmokeyMountainInverts]

I’ve had these two G. pulchra for 7 years. They were bought as slings in 2018 (separately). Temps for their room drops down to 65F at nights during the winter. As high as 78F during the day in summer months. Humidity above 50% year round, as it is a plant/greenhouse room. I’ve read extensively that these are very slow growers but they seem very small for 7 years old. I traveled with work for a few years, but always fed them every few weeks during this time. They only molt once a year, typically during the summer at this point. Is this a normal growth rate? Or should I be changing their feeding/enclosure to help them along?

Normal. These are painfully slow growers.

Yes very slow growers. Keeping them warmer and more feeding will speed it up but it's really not by much.
Get a Nhandu there pretty fast growers, Lasiodora Parahybana too, keeping that around 82°f, my last one went from around a half inch to 5 inches in a year.

Yep, very slow growers!
