Keep the sugar

I'd drop that light about 4" if you can keep those temps in check. What are you reading on the light level temps wise?

How high would you recommend from the tops? The picture may be deseaving and I’ll measure when they turn on

76.5 steady with lights on 69.5 with lights off

Thats at the light level or canopy level or below the canopy?

It started out 20” from net face. Some cola growth was aroun 6-10” so from peaks it’s approx 10-14” -guest

I'd try as close to the tallest bud as possible without having any ill effects. 10" for starters then go lower an inch every day and stop within 4" from the tallest. The plant below the trellis back right would certainly do better.

I only vegged under my quantums and plants started bitching within 2". Im runnig 96 chip boards at approx 25W (260mW/chip) and had no air circulation and no temp control but I'm sure temps got out of hand. I flowred with my 3070's@62W 4" from tops and got light foxtailing. Temps were also between 28°C and 30°C at the light level ans 24-26 at canopy and below. Each cob was covering 4 main colas

Second plant was a bit further away, maybe 6"

While lower its colas look amazing

Dropped lights so they sit 10” above top of tallest cola peaks. Took a lower branch off to dry and test for taste. I think I only have a couple weeks left. Thoughts?

How many weeks have they gone and yeah I'd say 2 weeks is a good ballpark time left,best way to know is check the trichomes.

My date based on previous grows of the same strain outside base harvest around August 8- flipped 39 days ago. I roughly calculated 47 days. But it’s a guess. Unfortunately I know the vanilla kush isn’t going to finish at the same time so harvest looks to be a bit more complex than I had hoped.

I’ll drop my lights more tonight. Temp went from 76.5 to 77.8 as the high. I’ll drop it down to 5/6in from top cola peak and see how they do, my guess is I’ll be getting close to 80deg. But with good air movement and loads of fresh cool air coming in I suspect I could run the canopy even hotter with no issues

I’m thinking about making some adjustments, it would increase fresh air flow during lights off (move more moisture out) but it would bring the temps down a few degrees. I’m wondering if this would help me gain possible some color variation, as I have witnessed from hot days and cold nights with the outdoor. Thoughts?

Mr.jiujitsu · Aug 1, 2018

The low would go from 68.7 to no lower than 67. The high I am not sure but with lights lowered I’m expecting up to 80. That’s a 13 deg swing, somthing I find outside to be nothing lol. My previous indoor grows are just over a decade ago and I didn’t have the resources or knowledge to care hahahah

MissBotany · Aug 1, 2018

Cooler night temps would definitely bring out the color of some strains. I’m considering adjusting A/C so it’s cooler with lights out since my current strain turn red, almost black the colder it gets.

I think you need a minimum of a10 degree difference to bring out the color

Lights dropped to 7.5 inches from cola peaks. I have a friend watching as I go away this weekend. Fingers crossed.

Mr.jiujitsu · Aug 1, 2018

Remote and local temp sensors should give me a good idea of what the canopy is feeling.

scubascrog · Aug 2, 2018

looking great! those are stacking nicely!

Mr.jiujitsu · Aug 2, 2018

Pretty large temp increase BUT I moved my temp sensor from on the canopy (possible partial shade from plants) to free hanging at top cola peak level off of light. That being said I expected a jump and a more realistic number. My guess is it’s really only about a 5 deg change (80 to 85). With fresh air, and good air movement I should be good, I’ll have to look for signs tonight and adjust if needed.
