Flipping my room tomorrow.
How many weeks from flip do you use DIF? And how many more * you run at night? I run 82* lights canopy on for 3 weeks, then i start to back the temps down.

But everything ive found to read its just to control yur stretch,after stretch its starts affecting flower sites. only a few plants do they keep negative dif threw flower to really elongate stem for sales.i believe pointseta is one they do this too.

I run 82 until week 5.5. I'll set about having the room at 85* off. Best i can do. If I run 76* on, my power bill will be $$, and I run co2.

Basicaly the concept is to keep higher temps at night then day,to get closer nodes??
Click to expand...
Ive never heard it referred to as "dif" but the concept has been around for a long time. I remember reading an obscure book on growing about 12 yrs ago that stated u can increase ur yield by 25% just by increasing ur night temp to 10 deg higher than daytime. The book was called "super charge your garden"

Lights should always be on at night. Higher temps cause a whole shit load of issues. My favorite is mold

Nope. Thats not true at all. Lights def dont need to be on at night. And its humidity that causes mold not high temps in most cases

Interesting...first time i read anything bout regions will act differnt from trying it..seems like instead of a scrog which u want to stretch to fill yur net,it wud b better suited in a s.o.g. setup.the pic of flower kept that one very short/stout.mayb instead of 12 under 1khps u cud cram 15 using this method..i might switch gears here..
