Ahoy there mate,
I will be updating my post on light manipulation soon, but let me break it down real quick.
Everything that grows, grows and lives its life cycle under light manipulation from the sun. When you grow your ladies you place them under a light schedule for veg, but you change it for flower. That is light manipulation.
I will be starting a schedule of 21.36 light period, followed by a 12 dark period. I will be on this schedule for two weeks and then change back to 12/12. I did not make up this time, I researched it.
Objective is to show the growth potential in size and yield with just 2 week of playing.
Since, I am growing White Widow I will explain how to use light manipulation to make White Widow turn white when the time comes.
One very important fact when you grow using light manipulation, never interrupt the 12 dark period.
This is not necessarily a new thing; it has been around for awhile, but kind of new to cannabis growing.
Hope this helps.
Stay safe, and grow well my friend,
Tok..
