BTW, are you 'mainlining'? Looks like it. I found a great tutorial on the subjet. Just google, 'grow weed easy/mainlining'. The tutorial is by Nugbuckets, & he developed & named the technique. He also explains why it works so well, mainly about the equal nute uptake by each cola. Very interesting & informative. I was almost there with my technique, & after seeing this, I tweeked it just a little to get what Nugbuckets has going. Check this out! You don't wanta miss it!
