I take my temp measurements off the thermostat display on my air handling unit. To me that's a good average of the ambient temp. I would think that if I measure canopy temp they'd be right about 80 degrees more or less. So maybe I am doing what you guys recommend but giving more of an ambient temp reading when asked. I don't really put thermometers all over the room to measure all the different temps. When adjusting the ambient temp to above 80 I find the plants start to crown a lot more than I'd like. It maybe lead to better yields but I'm fine with the results I get at my settings.

That's so funny to me bro, that is totally the same cut. I get the crowning too, I also see you get the late flower cup on the fans, never been able to figure that out. They look a smidge overfed, but fuck there beefy. How far do you take this cut? I wouldn't trip on temps at all, your doing awesome, if anything I would drop the temp in there and color them up, also gets that real deep cofee hash thick smell when it's colder.

Also that's a great point about the air handler, fwiw my display reads the same temp my middle thermometer reads (what I consider ambient)

I was trying to find the actual thread about the correlation between heat and CO2 (increase one, increase the other, to a point), but found this first.

How could you possibly argue with the unimpeachable "my buds are dank" defense?

You can't, can you?



FYI, sarcasm. Context is biting me in the ass lately. There's a pretty good explanation on the second page of the above link.

I usually take it out 9 weeks 63 days. I cut as early as 60. I'm gonna give them straight water five days up to cut. Ive been feeding 2.5/8 for almost a week now just experimenting with what the gh chart recommends.

I still haven't got this plant 100% normal. The yellowing has got better, but still there. Have adjusted feeds and all that. Buggered if I can figure out why it's just affected those few colas. I'm in week 4 now, so hopefully get it righted before I hit it up with the PK boost in week 5. Doesn't seem to be affecting growth, but no doubt it's still a worry.

Aside from that, everything else grows pretty good. This Jack Flash is doing awesome things compared with the random cuts I'd been growing with prior. Good genetics is an absolute fucking must. Just need to get the nuteage sorted.

Yep sounds exactly like the right flower time too. I like the 2.5/8 for final push. I just did some peat where I followed gh schedule the whole way, I liked it.

So your saying just a few colas are yellowing? Pictures ? ARE THEY THE ones directly under the lamp or anything like that? Sometimes when I get a funny looking top or something I start looking around at the environments not a hot spot, the lamps aren't too low, no osci is hitting it too directly that kind of stuff.

Yes I run at 85 - 87 with co2...thats the target temp

Lol no you don't, bet you $50 you run an air cooled tent. Here's the thing, I'm not trying to be a dick, but the normal battle cry of everyone who hasn't done it is 85 with co2. Almost no one runs that hot long term successfully. I believe dhf did here and I am sure there are others. I have never seen a garden in real life that runs that hot.m was just t with a friend and he was pointing out how hot gh run, but for whatever reason that is different than inside.

Anything that is gonna go wrong, at 85 degrees is gonna fold hard and fast. Bugs are gonna blow the fuck up, your gonna have to run 70+% humidity to stay out of vpd range. MORE THAN Likely your gonna fight to get the humidity that high. Frankly, if the humidity drops below optimum but above vpd, you are going to salt ball at those temps because the plants re gonna drink like crazy and the salts will build up.

It's not impossible, it may be the right way to go, but only on the internet do I hear oh 85 is the sweet spot. Ya it may open the stomata a bit more, but certainly a lower temp with co2 is absolutely beneficial and you avoid having a garden on a razors edge.

Maybe I have been hanging out with the wrong people' but don't see garden a running in the mid 80's really prefer to top out around 80, with co2 set around 1000 (if it was a gen I would run 1500 at those temps). I cool it down around 4.5-5 weeks on a 9 week cut. I drop it again around 6.5weeks to about 75 or less

For most of the kushes that is perfect, the kush hulk is running a a perfect example of a plant that likes this kind of schedule. If I was running a bunch of blue dream or cheese or something I might go higher (I probably would) but for whatever reason, these plants definitely do not respond that.

Guess I could of been a little more specific...I do run an air cooled tent. I do run around 85 for the first 2-3 weeks of flower with around 65% humidity then drop to around 78 and drop the humidity to around 50. Its def not long term.

No worries my friend, believe me this is common. It really does seem like a good idea, but when you do have the power to set any temp or RH that you want........you won't set it that high, lol.

It really also depends on what genetics your running. Some like heat and blow up, some tard out and crown like hhulk was mentioning. that is a really common look to some of these afganica dominant genetics. When they do that, they tend to not want to push out those delicious greasy calyxs.

I love hybrids, I had a cheese cross that literally got right the fuck up to the bulb, maybe 3 inches off the glass, and that thing just sucked it up, and wanted more. looked for pics just now, all i have is a pic of the crown of lowers that was around the cola. I love this cut :)
picture.php

It was definitely hot up there, but that strain loved it. So i am not saying that it is outright wrong, its just with some genetics its undesirable.

I was hoping I had a pic of some bub from that same run, but can't find it, its a mess. That would have been the perfect example. Anyway you can see that one fucking loved it, and the bubs kind of tarded out and crowned and slowed down. Everything worked out, but different strokes for different folks and different temps for different cuts.

How much do you hate that combo meter btw

Absolutely worthless. The ph probes go out too fast! I spent a fortune replacing probes. I have a blue lab ph meter now and it works good.

LOL thats what i was gonna point you to. The bluelab is the only PH pen I have trusted. About the only thing those hanna meters are good for is perspective on nugs lol. I am actually starting to not trust the EC on the hannas, seems like they tard out on me every so often, gonna go bluelab or truncheon or whatever it is. I know where I am so I can usually catch the meter lying to me.

Yeah the hanna pens are crap. They're finicky. I have a separate blue lab ec meter that seems to do the trick and does not require calibration so I use that to just check the mix. At this point we should know what the solution comes out before it knows. So ya its good to see the consistency in these pens. If I bought another ec meter I'd probably do a truncheon as well.

I was thinking of getting a bluelab combo, but then I started using jacks and I never pH anymore. I have a super cheap $20 EC meter that seems pretty consistent to me. I check my mixes all the time and have never recalibrated it and it's always been consistent. I feel like the pH probes are way more likely to fail. Good thing I don't need it. :dance013:

Are you not phing because of the two part chelate thing or because you know it's coming out right at 5.8-6?

You can't recalibrate a bluelab truncheon but I think the company fixes them for free if they go way out of whack- so says the guys at the hydrostore. Mine is 10 years old and I test the reading with some 1000ppm solution. It reads 950 so I just have to add 50 to whatever reading I get. My 10 year old hanna pher still works great if I recalibrate every few weeks or month. I always have my GH ph drops handy to test when in doubt. piss yellow is piss yellow and the drops never lie.

I have never had a ph probe last more than a year, in fact I don't think I have had one last 9 months. I store them in the 7 or the storage solution. So far extremely happy with the blue lab so hopefully all that will change.

10 years ago they didn't make them so they would burn out every few month$ :biggrin:

Jack's in RO comes to ~5.4, at least for me, this is a guess because I have always used the drops. For whatever reason it seems to work just fine. My runoff is normally between 7-8 for whatever reason that is. I don't ask questions and try to over think it if it's working great! :tiphat:
