Hey guys I came across this in the FAQ section and thought it was very interesting concept and was wondering if anyone has tried this and can confirm its validity. Sounds great.

larger yields

How do I manipulate the photoperiod for larger yields


[DISCLAIMER]: This information is provided as experimental data and not fact.

The only photoperiod manipulation from years of experiments that offered discernible improvements was this adjustment made for 1 or 2 calendar weeks at the point of maximum flowering rate: Daylength of 21 hours, 36 minutes with a dark period of 12 hours. To accomplish this, you need a 7 day, 24 hour digital timer. During a 7 day calendar week on Earth, the "sun" only cycles 5 times. This permits easily switching back to the regular 12/12 at your discretion. You may want to only alter during peak flower production to stimulate the plant's metabolism. Using this photoperiod throughout the flowering cycle will cause this:

A variety that takes 49 days of 12/12 to mature, won't see 49 - 12 hour dark periods under 21:36/12 until almost 10 calendar weeks have passed.

The total increase in light energy is almost 80%, which will produce larger yields, if all of your other enviromental conditions are kept optimal.

The total increase in flowering period is only 40%, half the potential room for improvement. This means you don't have to be perfect to win out.

Selective application of the 21:36/12 photperiod for only 1 or 2 weeks extends the wait only 2 to 4 Earth days, which makes up the missing 2 complete day and night cycles each week on Planet Ito. This permits the additional light energy to be provided without purchasing additional equipment or overloading existing circuits, which maximizes the existing system's capabilities. The main advantage is that matched with co2 and optimal nutrition, the plants metabolism will increase dramatically. I have only successfully tested this photoperiod for two weeks. The potential for a net increase of 40% over the entire cycle (80% increase in light energy vs. 40% longer wait) is worthwhile. Don't be afraid!

I tried something like that for my first grow. I got 3 hermies outta 23 girls. And i didnt know. Now i stick with more conventional methods.

hmm so thats neg-1, pos-0 thanks for the reply

well if you plant hermies that means it is not pure female. its not even that hard to find those bannana dicks. hermie seeds are good 2. good thing it was only 3 did any of the other plants seed?

light stress is the most common stressful event that causes hermies.
you have to be really careful if your seeds are feminized bcuz they are even more likey to hermie when stressed.
