75 to 85 degrees is optimal for healthy cannabis growth. also keep the humidity between 40% and 80%. I noticed just a small amount of stretching. If your using fluros you can place them two inches from the plant tops to halt the stretching brother. Other than that a damn good first attempt. Many growers quit if they fail their first grow. Errors will teach you so never give up. The more mistakes you make the more you will learn from them. Good job. :thumbsup:
