Third , yeah they are good at lights out. I water last 30 min before lights go out and that keeps them moist till lights on. Took a lot of tweaking to dial in watering and environment. They all play against eachother . It's a balancing act , but works for me, thank god for controllers

How are you not getting mold running that high of an RH?

Mold is a product of not enough "wind" in the room, not a product of high rh. I challenge anyone to prove me otherwise . As I've literally never had budrot or mold indoors in over 10 years. My room feels like a tropical storm though. Every single branch dances In the breeze. If they didn't, they would rot, but that would be because of stagnant air , not high rh. A lot of miss information about high rh and temps going around from people without first hand info or badly designed rooms with bad experiences. Who think 75f and 50% is ideal, which its far from unless the lights are out and even then it's still too dry. And if you run co2 at those temps you might as well burn you're money, as it will make no difference. Like I said I'm not going to convince any one . They can stick to what everyone thinks is ideal. But I trust my plants and eyes, not hearsay from growers who never step outside of the box of what others do and experiment

And another reason people are scared of high rh is pm. But pm is systematic and lives in the plant , so if you have pm living in the plant and it pops up, the issue is not rh but you having to rid your plants of pm altogether

Hope that clears it up. Everything has variables to it

[DJM]

As it is you don't want to dry or cure flowers any lower than 62% so running a room lower than that at 50 is going to effect Youre product negatively . I've done the side by sides to see that myself. I never go lower than 65 and dry in 65, cure down to 62 for storage

yeah it may sound crazy that feeding 6 times a day will create no salt build up ...seems counter intuitive ,but ill explain why that is the case...when water travels through the medium, its contained in its vessel of water..as that water dries within the medium, the salt looses its vessel of water and becomes trapped in the medium, leading to salt build up...allowing the medium to try out even slighty, creates spikes of ec/ppm in the medium...keeping the medium moist at all times does not...the first grow I posted, I feed the same amount of water to each plant, except I did 3-4 times a day..with this the medium did dry out slighty, making salt build up an issue and run off necessary...however when bumping the feedings up to 6x a day, the medium is always wet and salt build up is not an issue as the nutrients are always contained it that vessel of water...ive been monitoring the run off every 3 weeks, pouring extra feed through one of the pots to give me just enough run off to test..after week 5 of feeding 6x a day, my runoff tested at 925ppms, when it had never seen higher than 850ppms..last week the reading was 928..so only 75ppms of build up after 42 days of flower and a 3 week pre veg...that amount is a non issue...I aim to keep run off under 1000ppms in any medium or scenario..by flush im expecting it to be in the high 900s

its all about keeping the medium wet...when I grew in wool I used wet and dry cycles and only fed at 700ppms..salt build up would spike during each dry cycle and rise as much as 300ppms per week..i gave plain phd water every 4th feed to counter act that spike..feed strength, run off, water to air ratio in the medium all play crucial parts in a stable medium and the presence of salt build up..i wouldn't feed at 850 ppms if I was letting my medium dry, in that scenario id max out at 700 like I use to...its a delicate dance playing all the elements against eachother...people cant feed high successfully in coco because they are letting the medium dry out.. a lot of hearsay around the subject, some say dry it , some say don't.. I trust my eyes and meters...and imo if you are not feeding coco atleast 4 times a day, you are not unlocking the true capablitites in coco..the more you feed the wetter the medium..wetter the medium the higher you can feed and more nutrients they can absorb, leading to faster growth and a much more stable medium,,,ive tried water every other day, everyday, twice a day, 3, 4, 5, 6...the more I feed, the better results..so much so that i may go up to one feed every hour next run

with that said, multifeeds only work with A. an undersized rootbound pot and B. a thriving and thick root mass...if you throw and under developed root system in too big of a pot and try it , its a recipe for disaster...roots need dry cycles to thrive and expand...once root bound is when you want to start multifeeding...during early veg I use a wet and dry cycle and only start muti feeds in the final container...I do this to encourage dense roots mass as the dry cycle make the roots branch out in search of water...keeping them wet early on will not and will retard root growth ..once in final containers I start 2x a day and bump up as necessary to keep the medium wet...by flip im running 6x a day...this is with pure coco..if cut with enough perlite, once could multifeed from the jump with similar results

a lot more than what you asked but wanting to address the subject and variables for others interested..hope that helps some people out there get a better understanding of their medium and the elements that effect its stability

By far the best post I have read on Coco, it all makes sense and wondering what you are using to get the bomb explosive root's ?? I was using hydrogaurd and I see good roots but yours are crazy. My Mothers are root bound in 3 gal pots and Healthy cant wait to get a drip system going for my plants.

[Weeded1s]

Curing stopping at 62 rh is complete bs..if anyone can please give scientific reference to verify this...im ill eye balls.
Also as i always say. to each their own... but im still not running 70 rh in flower...no way no how.
just how i roll.
ex: 1 fan dies for 24 hrs and theirs gonna be major major issues.. and in flowering i totally disagree with this high of a humidity...even with the vpd chart. I dont grow leaves .. i dont want bud rot inside my 1/2 oz nuggs..been their done that..lots of air circulation and it still happened.
Pm is everywhere waiting for the chance to spore up and bud rot happens from excess rh....out door plants in windy rainy weather still get bud rot right?
its obviously workin for ya ..and im by no means knocking u or your style.. it just seems xtra risky for what potentially could ruin a whole crop.

lol love how kids with little tent grows try to give opinions on commercially growing in large rooms. Laughing too hard to even respond to that. Now I remember why I don't post on ic, every swinging dick with a tent and a 600 watter thinks their a guru , trying to teach you how to grow. This ain't my first rodeo. I'm taking time out of my day to come here amd spread knowledge , not argue with kids about what I know to be fact. So either come with good vibes and a constructive comment or stay out of my thread , and keep you're inexperienced opinions to yourself

[FlowerFarmer]

I think your yields speak for themselves.

High RH while keeping rot at bay with proper air circulation is the key to larger yields. There is just too much evidence on the web to suggest otherwise...if you look for it as opposed to following the mantra that low RH is a mandatory. Heath, Krusty, DJM... pretty sure they all crush it while contributing higher RH as a good part of the reasons why.

Cannabis is essentially a tropical plant, derived from the cannabis plant (cannabis sativa). It grows wild in many of the tropical and temperate areas of the world.


Keep up the good work DJM. Straight killing it and keeping it barebones simple in the process.

Thank you. Glad it was insightful. Honestly I use no special root additive. Or teas. Just base nutes and love. The roots are largely due to the environment they are in, as that plays a much larger role in the health and abundance of the root system than any additive can give you. And the health of the root system translates directly to the health of the plant. Sadly, environment is the element people experiment the least with, when it's the one that makes the biggest difference. Take two plants, put one in a dialed vpd environment, put the other in a regular cool dry room. The difference will be day and night , below the surface of the medium and above

Hope that helps

Thank's man, Im subbed , as of now I only use a few thing's the two nute bottle's some cal mag , coco. Im a Nube and trying to keep it as simple as I can with the little I have to work with. I will be trying to use your method's in my grow's. Im running a good fan with lots of flow through my room. Im slowly putting my room together. I could just get my Bro and say what do I need to do to grow the Tree's like he doe's but to me that is no fun. I like to experment and figure it out my self. And read and learn and use idea's that have worked for other's. Year's ago I used Rockwool cubes and was so green I messed everything up but did get a few clone's to root in rockwool, but then quit all together. I have been successful in cloning in coco and a home made cloner, and I need to go back and give the rockwool a honest try. Thank's UC
