What time of year is the natural light cycle on an 8 hour light 16 hour dark schedule,the correct answer is winter time,this is telling your plant it should be dead,not a good thing.
Please stop listening to your friend on any subject about growing,people like him like to talk all kinds of goofy shit they know nothing about,it makes them feel cool,i have a good friend who smokes like an ounce every week,he thinks because he smokes tons of dope he's a know it all of growing.
This guy has an areo garden & thinks he'll get a pound out of it,he was showing it off to me but he has no idea i grow,he started telling me about how once the plants get bigger how he will reinforce the light with black light to replicate the hydro method where the plants are grown under water
I just kept saying how cool it all was.
People are idiots,read & learn what you need to know from grow sites, not morons who like to talk.
