geez my clones are about 21 days from root and dont look nearly that big... although im only using 16 Oz hempy beer cups do you think this is the problem? ALso i dont have a pH pen yet (should be here monday) and I think the pH been quite high. I have one of those pH testers for fish tank where you take 5mL of water and drop 2 drips into it and shake and compare to chart but i have feeling this is very inaccurate so im looking forward to my pen!

how big are the containers you use?
