Now I am seriously impressed. I really want to see some pics of that run please. And other than SoG, what factors do you believe were most responsible for hitting that level? What strain was that BTW? Details my friend because I want to replicate those results, or even close.
This was done long ago in an indoor Gorilla operation (see above). There were no real pictures taken in those ops back then, Sorry but, I still don't take many pics. Even with a craft lic. and my patient #'s being with in my #'s limit... I don't take a lot of pictures.... Habit? Wife's request?
SOG and it did take 3 tries to get it right...
DETAILS:
I built a steel framed unit that held a 2x2 flood and drain tray. This was our test/dial in unit for the incoming The res tucks under the unit and the pump push's up through the lower drain strainer. It also drains right back through the pump when done cycling.
There is an extended 4" tube that comes up from the lowest drain area to be the fill level as the pump runs.
I (we) used Rockwool cubes of the 4" size - we pre-treated them.
There were 5 cycles a day - 1 right at lights on and the last right before lights out.
We used Hesi Nutrients (hydro), as directed....
Added CALi-MAGic at 5 ml per.
pH was set at 6.2 and allowed to drop to 5.8 and re-set to 6.2
The 33% refill rule was used exactly.
72-74 deg F held.
RH held between 47-52%
The strain was Greenthumbs G-13.
They were flipped at 8" tall.
They ran 76 days.
There was Mylar surrounding the area at 6" out from the edge's.
Mini fans were run on and below the canopy.
Questions sir?
