Under anaerobic conditions, yeast (Saccharomyces cerevisiae) harvest oxygen from glucose yielding ethyl alcohol, and CO2.. They actually evolve small quantities other other things such as ethylene, which is a plant hormone associated with ripening.. Alot of ppl already know you can produce CO2...

I've created/adapted this for those who need a timer that can be programmed to cycle at periods other than 24 hrs.. Good for things like fans/pumps/heaters/lights.. This version has no second resolution.. Its extremely easy to whip up a short period timer as opposed to something that can...

I'm trying to decide about next year outdoor.. I live ~42°N in the great lakes basin (SW Ontario).. This year as of now there has been no frost that I've seen, but my dad says he's seen a couple light frosts in the last week.. It can be a pretty brutally damp area though,, Basically come...

A friend of mine has a mother plant kind of.. Its a higher generation clone who's genetics have been passed around for quite some in a circle of ppl who really don't know anything about growing.. This one seems like its decently healthy, its about 6" tall, with a good root system.. Older...

Has anybody actually tried to implement this method for CO2 enrichment, or have any experience running ozone through a filter, and can comment on carbon depletion? If anybody is wondering what I'm talking about, C + 2 O3 -> CO2+ 2 O2..

I know you don't need 100% sunlight every minute of daylight, but how much is yield typically hurt by various amounts of shade, assuming all other factors are decent? Theoretical experiment: For a strain like say White Widow, if you were to plant identical clones in identical giant pots, and...

Whats the best way to keep a plant (a fairly resilient clone) as small as possible (with minimum stress) for as long as possible, to sustain it until next outdoor season, with as few cloning generations as possible (ideally none)? I'm familiar with topping/FIM/LST, but these alone eventually...
