Going from dirt to aero "Harvesting a nickle bag every so often"

A little over the top. I got three posts. 2 of the posts are 14 holers and the other is a 18 holer. I'm hoping for a lb out of each without C02 but that might be overly optimistic. The smell is getting intense. I went to Home Depot today and got a little jar of citrus gel for odor and also a bag of volcanic rocks designed to take care of stench. My exhaust runs 24/7. I had to go back to college to re-educate myself and I don't like student loans.

Here is a beer held up to a bud for comparisons sake. Also, here is a overhead shot of my grow, all green in there, wall to wall chaos. started the flush on UNO (#1) on Saturday and then I'll do a final week of water and Sweet Citrus from botanicare.
