Sorry for such the lag for an update.. I just got some time so here goes..
I harvested 4 large OG's and one small humboldt purple three days ago. That is when all of these pics were taken.. The buds were lookin great and some of the OG tops actually turned purple

The humboldt purple turned out great but was very small due to the short veg.
I have run into a couple problems with the aero system.. Their is not too much root space but the plants are showing insane growth rates. About .75" per day

They all have started to show signs of buds but there are many things i would have done different if i could have..
Things i would have changed:
*Used a larger PVC tube- 6" or larger
*Not ran the 1" tube inside. I would have just mounted the sprayers in the top or bottom of the main tube..
*I should have ran all of the same strain because you will see in the pics, my headband is almost 2 feet tall now. and i need it to stop growing so the others can catch up
There were many thing i would have changed in the aero and i will next time.. So if you wanna try aero perfect this idea and make it much more efficient and more root space.
Enjoy the pics and stay tuned for the final dry weight and i will continue to update with my next two plants i will harvest soon and also the aero! enjoy!
