I agree temp,RH and a large swing in temps between night and day isnt the best thing
Jack Herer & G13 in LPA system, does it look good?????

Well, now that we both agree someone asshat will have to log on and say that it doesn't have anything to do with night time temps or humidity or whatever.

So u DON'T want huge temp swings???? What would be to much of a drop? Say the room runs @ about 85. Really? An 8 week flowring jack?? I don't know man, I've heard that the Jack could even go 11 weeks in some cases. I guess it all depends on the phenotype. Please guys, come back tonight. When I get off work, I'm gonna snap new shots, would really appreciate it! Good day mate!

No, you don't want big swings. 5 or less would be ideal. It is strain dependent but all plants react in similar ways.

Oh yeah, please keep in mind that the larger temp differences and rapid pre-nigt cooling is not as applicable to mj as tomatoes. Rapid cooling is a strategy to increase sugar content as it is a temperature dependent (endothermic) process. The fruit has more mass than the leaves and will cool slower. This temperature difference will cause cessation of sugar assimilation in leaves and increase translocation to fruits. Mj fruits just don't have the mass and water content to hold heat like tomatoes do. Or at least that is what I believe. I lent my laser thermometer to a friend and he broke it so I have no way of observing leaf tissue temps.

162Grams dry is what i harvested per plant at 8 weeks flowering/ 6 weeks veg. frostiest buds ive come across, i was surprised because jack is not relatively a big yielder.

If you have bubble hash bags, pm me for semi-top secret hash
Making tip. Works so well I'm keeping that one to myself

Buds looking great!
Cut your nute PPMs on your LST's. Your burning them. No burnt tips! I would say 600-800 at that size.
Also remember, the hotter your room, the lower the ppm as when your temps increase, so will transpiration. Your plants will uptake water to stay cool...and with it, all the nutrients in the solution.
