Of the 3 applications that call for simple CHO sugars, carbo-loading is the one I understand the least. (microbe feeding and fermentation being the other two.) Good info and interesting article. Nothing beats getting the current science from a guy in the lab who's running experiments on the subject.
my2p It's already been brought up, but bears repeating- don't overdo it w/ the sweets, particularly during the end game. I use as much as 1T/gal (soil) in tea/brews early on, but much of the sugar is being exhausted in fermentation and micro feeding. (FWIW- I'm going for an anaerobic and aerobic balance to produce facultative microbes- too dense to discuss here. pic below)
1tsp/ gal during the 2-3 weeks before harvest would seem to be more than adequate for carbo-loading. Besides homogenizing and weakening the strain's natural flavors, an overdose can actually lead to sugar coated buds that bubble when they're lit up, burn black, and are harsh. Seen it w/ my own eyes.
Bulk feed molasses is cheap, (approx $5/gal out the door), and has a higher brix than Grandmothers or Brer Rabbit.
The Mash Pit- fructose, citric acid, d-
limonene, yeast, molasses, and raw nutes. Aerobic <-> Anaerobic = Facultative
I'm putting off a camera purchase to purchase, among other pressing things, a brix meter, (refractometer), to get a closer real time glance at a plant's CHO level and nute uptake efficiency.
