ok.

It is a personal choice for light times, but if you grow out doors you will notice that within 3 weeks after summer solsis your plants begin to flower and light times are 16 sunlight 8 dark and only period of 45 min is less in total light from summer solsis. It is not geneticaly programed you have to do 12/12 the plant senses the decrease in light time and winter is comming. greensman.com explains this very well.
Jerry Garcia 2007 Reviewed by Jerry Garcia 2007 on . Grow Box Help. Is my Setup Good? Hello, I'm in the process of doing the research to build a grow box and grow some of my Miracle plant. Attached is my general box blueprint, along with airflow plans. Will this work ok? Any other things I should keep in mind? How much power should I use for the intake and outtake fans? Also, I was thinking about putting a overhead 600w light. Would this be enough? I plan on growing 1-2 plants. Let me know! Thanks! Rating: 5
