I can say for sure GSC doesn’t like high heat and it will stunt growth.

thanks !! could have done that fro 1-3/4 weeks - GSC seemed way to small even if it is an about and should be at least close to 10 inches or so ?

Yes, besides heat and genetics there are a few things that could keep a plan from growing much. Light, water, and fresh air (co2) are all needed for photosynthesis. Being short of any of the three will hamper plant growth. Pot size can also play a role, as well as root conditions, and media/nutrient combination.

If you want good clear help, it would probably be best to fill out support ticket. That way everyone can get a clear idea of what you’re working with.
