They're looking good @cannaworms!

Sometimes the stage between seedling and mature adult plant seems to take forever and it really tests the patience, but overall they look healthy and happy.

If the soil is not nutrient rich they might need some added nutrients, it's a tough call though if the temperature is low because low temps could stunt the growth as well, and adding nutrients in this case might stunt or damage them. If it's chilly that might be the main culprit slowing them down.

Keep up the great work! Can't wait to see how these turn out!
