FARRED

I retract my earlier statement and say they may need less far red due to being self flowering. Coming from climates where plants need less light to grow as i would imagine ruderalis grows very small in the wild.

thnx BraveheartGenetics i know all the date from dr bruce bugbee and MICRO etc, i ordered UV fixture so very interesting! but what is your opinion knowledge about farred? and do autoflowers have the same Phytochrome state as photoperiod?

Sorry, going to have to disagree with UK420Show about UVB. Lots of research has been done with this. As far back as the 60's. The results were staggering. By applying a maximum of two hours of UVA/B light in the last couple of weeks of flower at mid stage of light schedue, can increase THC/Resin buy 30%. This is due to the plant producing more resin to protect itself against the UV light. It has to be at the end of flowering as studies have been done for the affects at different stages. Lighting in veg will cause the plant to create a resistance to UV so using it at the end shocks the plants into producing more THC. I hope this helps, good luck and happy growing

Yeah granted pal You already knew all of that lol im pretty sure it will benefit them but like UVB the research isn't there yet I dont think and if it is I dont think its a huge difference. Sorry I have never experimented with far red maybe another grower has :)

i use 50watt farred COB and im on a 18/6 cycle i grow auto's and was wondering of autos use the same mechanisme /Phytochrome state as regular photo period , im also gonna use UVA/B but there is not enough data with autoflowers , your answer is great info btw but nothing new but i really appreciate it!

Yes I think so they absorb the light in the exact same way as photo in my experience. Why would you want to have 13/11 i know one more hour of light should create a bigger yield but Im sure you will run into other problems but yeah it can be done :) Far red is electro magnetic its not registered on a par value so its hard to evaluate it was never considered to be photosynthetic but its turns out it actually is but its not very good when compared to the other spectrums. the only benefit to far red will penetrate actually through the leaf so light what's beneath too. If your asking if you should use far rad for one hour before lights go off then it could benefit her but i have never tested it. also fer red is usually used in plant which are considered "all day plants" which have flowering cycles of around 16.18 hours while flowering not like cannabis it is a short day plant with only 12 hours needed.
