The Gee Spot - You Finally Found It

I am going to tag along if you do not mind.

Geeman I got a question. My leaf temps are anywhere from +/- 1 degree from my ambient tent temp. Taken on both plants at the same time.

Ambient temp in the tent is usually about 78 F. With rh at 60%. With lights on. Leaf temps are anywhere from 77 to 79 F.

My question is should I bump the light intensity up to increase leaf temp? My ppfd is roughly 450.

Ok 1st, are you taking the readings after at least 10 hours of lights on?

If so, you want a 2 degree difference at least. So 77 is already a degree too high, and 79 will be starting to choke off carbon.

The reason you need to wait until the 10 hour mark is because plants transpire to create sugars and respire to use those sugars. They respire at night to grow, using the sugars they built in the day transpiring.

In the at night she will raise leaf temps to be warmer than the ambient air to cause respiration, and as the day progresses they flip back and forth by fluctuating their leaf temps, until they use enough sugars that respiration completely stops and they go full bore transpiring to create new sugars for the upcoming night to do it all again.

So if you are taking readings too early the plant can still be fluctuating. You want to know how it sits when going full bore as that's when you get a true reading and can make a reliable adjustment.

If those temps are after 10 hours then you need to turn the intensity down a smidge, as you are giving her more light than she can use. Probably that her roots can't keep up. It's a way of matching light intensity to root/soil capabilities. Any excess light is light poisoning.

When leaf temp matches air temp the air can't wick away transpiring moisture, as she is leaking moisture at the same rate as air can remove it. When leaves gets warmer than air stomata start to choke from excess moisture building up, so they start to close and carbon (CO2) gets shut out. Without CO2 she can't create sugars, so tonight she won't grow properly.

Make sense?

Just thought I'd finally share this here because I had been kicking around the idea of journaling an organic small pot grow with an emphasis on high Brix. I had reached out to Gee about it and talked about some stuff with it and ultimately I chickened out on journaling it lol. Boy did I miss out on a chance to show that you don't need super big pots to achieve high Brix plants. Anyways this in my Northern Lights bonsai style plant at day 50ish. 1/3 gallon pot sitting on a perlite swick bed. The tents 20"x21"x14" 100w light set at 25% 20/4.

Thanks Stone

Does he say how often he uses it, and does he still add dolomite to his soil mixes prior to cooking?

He uses it every time he waters. He adds enough of the churn concoction to bring the ppm to 55-65. And he does include DL in his soil mixes prior to cooking.

Yes Gee that makes sense. I took their temp when lights basically came on.
Tomorrow morning I will break out the IR gun and take their temps again and see where they stand.
Thank You for the explanation that helps a bunch.

Wow G! You're killing it My Man! Small pots are hard. You need to be extra dilligent. You can't take a day off ever. Very nice, and a great example of following all the rules. Beauty man, freakin awesome and very cool! Thanks for sharing this. Is it done with Gaia?

Thanks Rob. What kind of dolomite does he use in his mix and in his churn?

Dolomite, or powdered dolomite, or prilled dolomite?

 

[Thirvnrob]

You have the option of pilled or powdered in the soil mix. Powdered in the churn & plant water.

Ok good, I kind of suspected so, but I'm glad those weren't your afternoon readings. The morning for you is the end of the day for her?

If opportunity knocks, take IR readings every hour during lights on. You can see what she's up to now that you know how it works.

High brix plants can photosynthesize better, so they can create sugars faster, so the can do respiration even during lights on to grow more, both foliage and terpenes/resins, and then still build enough sugars later in the day to do it again.

More growing time in a day and less photosynthesizing time.

Now you can see the value in having your light dialed perfectly. It creates maximum sugars but no stress from being over lit, and leaves more growing time.

She respires in the dark because she can't photosynthesize, but she can also respire in the light, as long as she still has sugars to burn.

A healthy plant can actually photosynthesize and respire simultaneously, using nutes from her leaves as she respires to photosynthesize sugars, and then replaces them in transpiration.

So early in the day leaf temps can't be trusted to be photosynthesizing.

Make more sense?

Yep top dressed until the root ball became to tight. Then I worked on making Gaia soup, 1 gallon water, 2 Tbsp of Bloom, 5ml of fish nute, and I used recharge to help keep the microbe count up bubbled for 24 hours. Dolomite water as needed, I only brixed her 5 times and needed dolo water once. Honestly without sitting it on perlite it would have been an absolute chore to water, the perlite base holds 1/3 gallon of water. I will be interested to see the root system.

I'll bet I only get at most 1/2 ounce of the buds swell like I think they will. This wasn't about the yield for me but just trying to test the limit. I have some ideas to improve yield maybe even try an auto flower.

Yes and I just snuck in and checked the leaf temps at the 9 hr mark of lights on. Ambient tent temp was 81°F. Leaf temp was between 78 and 79°.

I gotta get his book. I like big pots but one day I'll be too old to lug them around.

Have y'all heard of those upside down pots ? Very interesting,how would cannabis do in one of those ?

Someone mentioned it awhile ago but the subject didn't go anywhere. I've never tried it. I tried it with cherry tomatoes once but it didn't work very well.

Yes same here over the years my preferred pot size has grown considerably lol more roots,more fruits is a standard for all plants not just bud even flowers adhere to this principle. The plants are just healthier happier and more resilient. I want to do a few 20 gal runs so damn bad!! W training !! Uugh imagine the nuggage I could produce. A plant that free probly looks different to what I'm used too.

I would need a bigger tent lol. My last plant filled the 5 x 5 from a 10gal bag of dirt. A 20 would be humongous.

I would absolutely do a 1 plant 20 gal grow and just spread that thang for days I hate one plant grows cuz no insurance but I would def risk it for a chance to do a 20 gal. I would train it exactly like my newest additions to flower !! ...

I recently had 4 of my 6 big flowering girls herm in this hunt!! I saved my harvest numbers and transitioned 4 veg girls to flower w 2 left over in 1 gals. I need to find my keepers so. Flowering these too and experimenting. I would train my 20 gal girl just like this

Hey Gman and the Brix gang..........

While staring at the ceiling at 3 am or It could have been a stoner moment. I dreamed up the Juicer 5000. I tried it tonight and it squeezed out the juice of a leaf quite well. And sure as hell was easier than using pump pliers. There was absolutely no cursing and I didn't have to eat spinach for lunch.

I was able to get a small amount of juice just using my fingers. A couple of wrenches makes childs play out of the plant material. It works well. A small amount of plant material did oooze out the blow hole. Not a big deal.......Maybe a smaller drill bit? I bought a second nut just in case .This is only the prototype. 1.0

Materials......About $1.75 at the hardware store.

Two 1/2" bolts.
One 1/2" nut.
Small drill bit/ drill.

Screw the first bolt into the nut about even with the hole. Pack a boot heel of green in and the nscrew on the second bolt. Easypeasy!

Hope this helps the dreaded squeeze. Have a great night All.

That's a cool idea!
Now, I'm thinking on my pre-press mold for my rosin press....hmmmm...

Here’s some info for you. Hope the Rev doesn’t mind…

Thanks Rob. I only have 1 question.

Who's gonna try this for us all?
