Hey stink bud thank you very much. I actually built your veg unit, the one with the two totes stacked, I have a question for you, the reason for the two totes, is that to keep the roots out the water? And what's the purpose for the cage on the one you just posted for me? I noticed it on your other units as well. I appreciate the help, by the way, I went to buy your book, if I may make a suggestion , some people may not want @havestapound to show up on their Paypal, maybe stinkbuddies is less obvious... Just a thought. Thanks again.
