if you jus want clones you dont need to digg and if you wunt to transplant dig about 1foot from stock all around and about 1 1/2 feet deep then put dirt and all in bucket or tub filled with water untill all dirts off and then replant with new soil
if its in a different spot like the basement maybe to much humidity and if its heating up put a fan on the bottom and a small comp fan on the top so it pulls the hot air out
