How to reduce the cost of growing cannabis saving 30-50% on your electricty bill using the 12-1 lighting schedule.
The biggest innovator in the history of cannabis in my generation is Reinhard Delp. Not only did he invent and is the holder of the patent for ice water extraction, he has been building flower forcers since 1992. His new solar powered Sun-gate is the leader of the industry. He was the first to feminize seeds and sell them in Europe in the late 90’s. His process was done naturally, without the use of any chemicals.
No one is more copied but seldom matched than Mr. Delp, who to me is the top grower of our generation. The first time he impressed me he showed me 2 plants, planted next to one another, 1 completely covered in powdery mildew, the other completely clean and beautiful. He was developing mildew and mold resistant genetics.
In the late 90’s Reinhard brought back the gas lantern routine that you find in any college grade horticulture book, and applied it to cannabis. Cannabis needs only 13 hours to stay in the vegetative growth stage. The 18-6 lighting schedule in vegetation, actually stress your plants, that never get that much light in one-day outdoors. Cannabis is an outdoor plant. Growing indoors you should copy how it grows outdoors. No Cannabis growing in Afghanistan gets 18 hours of light in growth pattern. Most strains today have some part Indica in their genetic pool. Even equatorial strains don’t get 18 hours of sun a day.
The 12-1 lighting schedule is as follows 12 hours lights on, 5.5 lights off, 1-hour lights on, 5.5 lights off, and repeat schedule. The 1 hour on in between off period fools the plants that stay in vegetative growth state! Your immediate savings are 5 hours in energy costs daily, as well as your bulbs and equipment lasting longer. But how do the plants react to this lighting schedule?
You see immediate growth response from your plants, they are happy from the added rest time. By day 14 the plants tripled in size. The plants are bushy with twice as many bud sites without topping or bending, In fact when you top and stretch your plants out, you get many more bud sites than you would have had under 18-6 using same procedure of topping and stretching plant, your growing bigger and better and faster.
So your saving 5 hours daily in energy costs, as well as your excellerated growth pattern which also saves you time and energy and equipment use.
In the flowering stage, never use 12-12, start your flowering period at 11 hours on 13 hours off. When your are growing outdoors each day you get less and less sun light, you should copy the way the sun acts naturally in your indoor grow. So first 2 weeks of flower you go 11 on 13 off, the next 2 weeks you go down to 10.5 on 13.5 off, next 2 weeks 10 on 14 off, next two weeks 9.5 on 14.5 off and the last weeks of flower you should be at 9 hours on and 15 hours off. You’ll get bigger and better buds by copying the way the sun light works on cannabis outdoors.
Cannabis is an outdoor plant and you should copy the way it grows outdoors indoors. The only thing that 18-6, and then 12-12 lighting schedule’s do is make the energy companies rich as well as the people who sell lights and equipment, the more you use the more you spend. 12-1 lighting schedule is a more natural way to grow indoors and you well have the best results you have ever had and save as much as 50% in energy costs.

What if I am cycling plants thru my budding room?
I may have as many as 4 different generations of plant in my flowering room at any 1 time not all of them having been placed in there at the same time.
I harvest 1-2 plants every 10-15 days. One gets pulled, a new one gets germinated.
I can easily switch my vegetative room to 12/5.5/1/5.5 but what should I average the flowering room to?
I’d keep the flowering room at 12/12.
just add one hour of dark n delete one hour of light(11 on 13 off) then as it is typed up: the next 2 weeks you go down to 10.5 on 13.5 off, next 2 weeks 10 on 14 off, next two weeks 9.5 on 14.5 off and the last weeks of flower you should be at 9 hours on and 15 hours off. You’ll get bigger and better buds by copying the way the sun light works on cannabis outdoors. bless

Also creates an easily recognizable pattern by law enforcement officials. Especially with smart meters these days–you can easily be detected by the power company. (Not that BC Hydro cares about that up here. They were pretty stoked when we needed more power for the greenhouses on our small island, so they put up new poles, lines, and transformers right away, all in plain view of hundreds of visible Cannabis plants.)
