Roots absorb nutrient ions through porins

My biggest problem with vented rooms is where i live. I never got aroumd the fact that cooling or dehumidifying was impossible when its summer and its 88 degrees with 80% RH outside. Just not going to happen. In the fall/winter and cooler more dry days it was much easier. With vented rooms i was always at the mercy of what the weather was like outside. And crops were inconsistent because of this. I made the switch to totally sealed rooms with co2 and appliances to control the climate. Much easier....less headache...more consistency but its expensive as hell.

Never have. He needs to exchange his air in the room. That spray is a band aid, just fix the problem
I've just been chatting with the guy now.
He said that he topped 25 plants for 4 mains in a SOG set up and he has lost 8 main colas to bud rot, yet the other 92 so far look fantastic with 3 weeks left of 12 week flower.
I've been helping him tweeking his room. I'm not sure he can improve on it much now from my point of view.
It seems like one fan leaf shuts down on the big cola and turns crispy brown dead in a single day, when inspected, this seems to be the area where bud rot has established on the stem deep within the bud.
I suggested using colloidal silver on the infected areas to try and save them. But he takes the whole stem off straight away. He said he vaguely remembers reading something about colloidal silver 'hermi-ing' them so doesn't want to chance it.

Thanks for replying anyway :)

I spent close to 4k on dehumidifiers, bought the expensive controllers added fans all over the place and the trimmers still bitched. Nowadays when I'm ready they come running

What's his humidity once the lights turn off?

He may just want to cut @ 8 weeks before the rot starts to set in. They may not be as big but not tossing moldy buds and getting another cycle to 2 per year.
It's an option

The colas he has taken off with bud rot are from 8 weeks in. He has been drying and curing them to see what they are like.
I've had some off him, and whilst a it's fairly decent in strength considering it's early, there is absolutely no aroma or taste for that matter.
He was saying that this strain haze x northern lights doesn't get any trichones till about 6.5 weeks in and the terpenes don't really develop in size and ripeness until about 11 weeks, until then there is only a faint aroma of the N- lights with little frosting.

It's like you say though, it must be a spike humidy when the lights go out and the room air cools down, cold air holds less water, which will unload the water on the nearest cool objects like plant stems in the form of condensation. This is fine where the stems are getting some air movement to evaporate the moisture, bud deep in the dense buds it's establishing spores and creating problems.

I'm going to suggest he tries coating all the budsites with Vaseline after the stretch before the buds grow, on one or two plants and see if it makes a difference. It might hurt the plants though.

Thanks again for all your replies.

Sorry op, don't mean to hijack your thread.

If the strain doesnt work out....its time to change up to something that does. Ive had to do this a shilt load of times. Sometimes something just doesnt work in a particular set up.

I do not recall the brand of dehumidifiers we used. They where big heavy and blue though
And expensive as could be also like 3k each

I've been following these forums since the overgrow days, so yes I'd say I'm forum born and raised.

I've been designing my own hydroponic formulas for the past 7 years now and have made over 18 iterations of my formula, dialing in on the perfect nutrient profile. The reason you're seeing improvement in your grows has nothing to do with the bullshit products you've been adding. You're probably just better at growing than you were when you didn't use those products.

You say it's expensive to become "really" dialed in, but my nutrients are likely some of the cheapest on the forum. Generic salts.
Hey Church, I'm on your side, I believe also that plant absorb straight inorganic molecules..

Your formula seems interesting, how would you compare it to the Jacks Pro formula? I'm wondering if there is a real major advantage to switch to a custom formula like yours considering all the work required to buy the raw ingredients and making the right ratio formula (weighting everything out perfectly) than try to tweak it like you did to find the perfect formula..

Have you tried Jack Pro hydro or anything similar, what differences (improvements) are you getting from your tailored formula?

Thanks,

Download hydrobuddy. It will help figure out how much of each salt you need to make A+B solutions.

I have a DIY thread on it here:

http://rollitup.org/t/diy-hydroponic-nutrients-in-5-minutes.894332/

There are a lot of recipes in the formula database in a stock installation of Hydrobuddy, including recipes from the University of Florida, Howard Resh, and a bunch of other sources.

All I gotta say is try amino acids in 1 res, foliar til week 3 flower and call me after harvest. Shoot if just started flower, spray on a few plants til week 3 (I saw 3 cause they are fat for me week 3, some can foliar up til week 5) and see the difference

Well hold the phone my bro science platform seems to have tapped out. It's cool church it's not like we're telling you to mix your bottles together in concentrated format so that mixing is easier or some other delinquent bad advice. The beautiful thing we're sharing works with all nutrient lineups. Regards.... :)
