Light setup for seed production?

[killyouridol]

Does light intensity play a major role when growing plants for seed production? Are there any special considerations i should have when setting up a grow room for seed production? Thanks

yes, T5 would be best and you can work the height out. You would want the production area to have high humidity and temperatures 80/85f 70%+RH.
some growers use heat pads as well. what are you going to be planting in?

I use the same light I would use without seeds. Make sure you pollinate 6 weeks before expected harvest.

Thanks! Initially i would grow them in organic soil but i am willing to try any other suggested medium. 70% humidity sounds like a fungi / mold nightmare to me, do you keep that number when lights are off as well? Thanks

Don't use t5s and keep rh under 50%. Top seeds usually get ripe first, the ones on the bottom larf is usually last. Most are ripe in 5-6 weeks

Thanks, so you basically use the same setup and RH Temp parameters. Any extra N during flowering?

no, but I try to keep em green. Don't flush or wait until most of the seeds are ripe.

What kind of seeds are you making? How many?

Not planning on producing big quantities, will focus on R&D for a while so i wont be producing seeds on more than 50 plants until i find something worth producing

Are you gonna make fem seeds or just pick a strong male and hope for the best?

hey my bad as i didn't understand the question right. I was thinking of starting seeds after soaking them in water. I then keep my humidity and temps up so that it breaks the ground faster.
here is a chart i follow to keep the temps and humidity balanced.

how long does it take for the seeds to be ripe ? do seeds cure too or ?

most are ripe in 5-6 weeks. Some will germinate right away. Most do better if you let them dry a couple weeks.
