65% rh flower

Been growing a decade grown commercially and personally and I've followed the vpd chart before weed is worse quality. We all know high heat and light degrades trichomes so why push 90+ degrees ever? Why push anything over 78 ever?
Excuse my ignorance, but where is this implied when using a VPD chart?

Anything over 55% is a disaster waiting to happen of pm and other issues high heat is also gonna attract bugs like all hell

Why push anything over 78 ever? Your gonna come out with the same yield but of bullshit dreaded ugly ass trichome degraded airy ass weed. Sure massive colas that have barely any density look huge but why? Why would I do that when that weed can't even be sold for outdoor prices in Colorado at 1600 a plate. We pull stupid quality and barely get 2 a peice per lb here. The name of the game is quality and yeild not just yield. Your calyxes will have to open up wide to be able to breath better with such high humidity and heat. And again please tell me how many people you know period that pull over 2 a light consistently over 14+ lights on a personal grow single person running it 20'x20'? 2.47 is the most I've ever seen or heard of for anything over 4 lights. And he had strains he pulled over 3 a light with but when you run 8 strains not everything will yeild like that you get og's and cookies that like to yeild barely 2. Again decade of growing used vpd chart dont know one commercial grower who grows over 78° day time and I've been in about 40+ grows all over Colorado.
Constantly pull 2.5-3 per 1000w of light using VPD. The quality is great.

And im in no way trying to down what your saying but why grow weed no one will want? There is a guaranteed quality difference so if you gain an extra .2lbs a light hell even half lb a light it still wouldn't be worth the price loss and the pride loss when you show your friends some horrible ass weed lol
Kind of offensive that if it's not grown your way it's shitty weed. There is so many ways to do this. My temps and humidity are back into "normal range" by the time I actually have flowers.

Btw the edges are burnt because weeks 6-8 I'm pushing upwards of 2200 ppms. It works for every strain tho with my system even cookies just get some light burnt tips to know I'm pushing them
You are missing the point here. I am not arguing what works I am saying I bet the burns would be reduced with higher humidity. I get burns at half your ppm at the end of flower if it is too dry. They transpire to fast.

The chart works at other temperatures. commercial greenhouses use this chart to keep production up.

So do you taper temp and humidity down to "safe" levels for flower but have better results in veg? And may I ask if this differs from seed or cuttings?

I didn't say if its not grown my way it's shitty please show me where I said that please I said higher temps with high humidity is will give you shittier weed but again put words in my mouth please

What's wrong with 75 degrees and 65%? My healthiest plants have resided there. That's why I am interested in this. But worse results even in flower at 75 and 45%. Faster transpiration I guess is the culprit.
My dehumidifier is on all the time it's just the ac version that cools full time instead of heats 65% is asking for trouble with pm and other fungi. Most people can't keep a sterile room alot won't use eagle 20 even on a new clone to clear it. It's a systemic fungi people lose crops to high humidity I've never had any issues of bugs, fungi of any type since switching. Know people who keep pm with their high humidity but I guarantee my house is spotless and if something comes in with it it'll get sprayed and put on hold till a mother and can be cloned. Humidity is a disaster for a alot of people lowering it gets rid of a lot of potential headaches and adds to the plants liveliness I mean let me know if you find any burnt tips in my flower room or "dried" areas lol more than likely do to windburn than even nute burn in this 8'x 12' room with 3 fans on full blast 24/7. Keeping these parameters causes less headacheIMG_20161208_232242974.jpg IMG_20161210_024738630.jpg

That's at ec 3.4 they'll be at ec 4.2 next week till starve in week 9 veg at ec 2.1
I agree man. I bought a bigger dehumidifier when I moved near a lake here. Humidity ruins many crops and harvests in Michigan.

I just noticed that the burns during ripening came back when my average humidity dropped as winter set in. I use a whole house humidifier and a basement dehumidifier while I re circulate grow room air here as heat now. It goes out the chimney in summer.

When I checked my notes and pics. The same strains had no end burns as often and I Es struggling to keep things below 65% then.

I was merely pointing out that the chart is saying that my summer parameters were perfect VPD.

That's crazy that that happens I mean I can't imagine that raising my rh would allow me to push more ppms when I know ttystikk hits like 2.8 at most in tupur as well and burns and has 60-70% humidity compared to me hitting Them at 4.2 and 35% and they barely tip burn Which honest is again prob from the fans you get wind burn easy in low rh. When people hire me thats the first thing we go over is parameters. New growers need simple effective and user friendly. Putting em at 35% helps them get adjusted without getting any problems. Idk people grow all types of ways but beat weed I've ever seen period came at these parameters.

How many lights? Strains?
You said if you grow weed at high temps and humidity it will be shitty, fluffy bud. You then explained you did the complete opposite. You've said fuck VPD a few times through the forums. So directly, eh idk. But you got your point across...

6 lights per room. 4 rooms.

Blue dream. Lemon Larry OG. Sensi Star. Dairy Queen. OG Kush, Abusive and GG4.

Just switched to 315s also, so my grams per watt has sky rocketed. Now I pull 3-3.5 per 1000w of light.

Not bad but all high yielding strains by a long shot nice tho good size rooms wish I could just grow dream and gg4 and dairy Queen I'm breeding so currently every room loaded with tons of different strains hell that veg is all seeds from breeding projects never run any before just their moms a couple times. Got currently 45 strains in lineup always revolving. Wish I was in Carolina fuck could hit big yielder all day people want new and different Everytime here gets annoying as hell competition thick man fuckin ridiculous I go from Florida where paid 200 a zip for decent 280 for actual fire and growing there to a place where fire synthetic goes for 2 a plate organic 24 a plate. Games changing sucks thats awesome you can still move those tho. And I say fuck vpd cuz if I ran according to it I should be at like 61° lol and by my temps it says I should be at 60% which here is asking for problems. Every 3rd house in Denver is a grow house pm and bugs and types of shit is everywhere. That chart is wrong I don't anyone in commercial running over 50% humidity night and 40% day causes too many problems and weed isn't as good

Btw I can guarantee i have denser bud with my environment not even trying to make a pissing contest. Question I enrich at 1300ppm co2 what should my temps and rh be?
