Grape Diamonds R2 (Ethos)

Still good consistent growth in the 4th week of veg. She took the the transplant well but like the Bubba Kush her growth rate is slow. Both cultivars are just a measly 7-8 inches tall after 4 week of veg! I attribute some of this to the cold weather we have been having recently. With the humidifier in the tent at night, the lowest it dropped was to 54f! While its not enough to hurt the plant, I definitely want the temperature around 65-80f. Both the Grape Diamonds and Bubba Kush are now in the AC infinity flower tent. To combat the cold weather I've added a heated seedling mat to the bottom of the tent as well as lowered the light to around 19 inches. I also have changed my light schedule so lights are on during the night and off in the morning when the weather warms. I have a feeling that if the environment is right for the next week or two she will take off. I want to top her as well as the bubba but I don't want to slow the growth down at all. Maybe top in the next week or two?
