Hey space boy that has happened to me if i turn my exahust off and it stays to humid to
Dry out
Hows your air flow?

[teemu shalanie]

room temps? , dehums ? exhaust?, AC ? how many bulb room, talk to me ??

im all about humidity these days plants veg 30% faster and buds get huge at 75% humidity I'm only controlling the humidity in the last few weeks now. Sounds like you should just transplant to new coco I don't think pythium will take hold bad in coco like in dwc buckets you can salvage your plants

Its hit both veg rooms. One is a 1k and other is a 6 bulb t5. Its happening in both rooms though. Air flow has never been a problem down there before, but im not exausting the air anywhere. Same rooms ive been vegging in for a long time though.

I tested the ph of the coco out of the bag and it was good, but seems like it drops really fast once i pot into it, some tested as low as 4.5.

This chart is optimum temp/humidity combination, the orange part -

Hello ,hello
I have been using coco as a medium for 8-10 years now.
I use 40% coco coir with 20% worm casting and the rest of my mix mostly for aeration and drainage which goes hand in hand.
Chunky perlite@30% and some diatomaceous earth is what I use to make a loamy mix.
I use Bontanicare coco.
I get it in the bale size it seems to have more of the mesocarp then even the Bontanicare blocks.
The blocks seem to be made of more of the pith which is like dust more then the fibers.
Know that coir comes in 3 different grades with the middle layer know as the mesocarp it being more fiberous being the one a grower wants in my opium.
The pith or dust sounds like what grade you have it for drains horribly.
Have you seen the coco chips that is made into circles to give you some reference of what I am talking about.

Good job Ratzi! Nothing beats real experience.

No clue here regarding these materials.

With all that said, no calcium in your mix at all?

It is my pleasure Sir


Yes plenty of calcium around 65% of my base.
I just wanted to make coco user aware of the different grades of coir that is on the market and to try and stay away from to much pith "dust" for it never wants to dry down.
I get much of my calcium from oyster shell that is ground into a powder. I also use some dolomite more for its Mg. Some Gypsum and crab shell 23% calcium.
I also have started using some Calcium Bentonite clay more for its CEC holding power.
I think that calcium is the easiest element to source where Mg. is one of the hardest.
I have a list of what is in most things


I have seen that your not a big fan of Michael Astera of "soil Minerals" where I have been a follower of his for more then a few years now with his Handbook "The Ideal Soil" opening my understanding greatly.
Jeff Lowenfels "Teaming with Nutrients" and his "Teaming with Microbes" are other eye openers for any aspiring caretakers.


I opine that ganja growers and their mixes are like chefs in the kitchen with different recipes.

Time to graduate up to some real reading based on up to date science written by someone with real experience.

The more Mg you have in the soil, the less the plant picks up. It is an inverted relationship.

Waiting on dolomite is worthless, much less the fact that it causes drainage and purging issues. Use Mg foliarly and get your Ca and P up, the Mg deficiency will go away easily provided your K and Na are at reasonable levels.

With all those carbonates in dolomite, oyster shells, etc... you are not getting much calcium available to the plant. What is the pH of your water? Does it have bicarbonates in it?

I have been reading some of your posts, interesting for sure.
I see no deficiencies in my plants most times.
I use rainwater its has 0.0 EC and 6.2 pH
I am a old dog so new ways are hard when I am so comfortable.
I will continue to a better understanding of what you are saying after reading your posts over a few more times.

On another note it is my understanding that to much P mixed in globally retards the mycorrhizae growth
