I didn't know there's an 8 week SSH pheno, I thought it was around 11 weeks like the NL Haze. The trichome cover on this pheno is impressive....

I found very special beans guys....the old Barney's NL Haze in genuine packaging. They're old but germ and real soapy haze taste with tight calyxes.

If you're interested, pm me i'll send you the link to the shop.

anyway, great job here Chriet

You dutchies are quite un-beatable on the growing matter...

I don't like to sound too sympathetic haha but quite honestly the sum of knowledge I can scatter here and there on this forum sections is impressive

I don't fully understand everything but yeah quite a few octaves above the rest...

Thanks a bunch everyone, lostchild, scirocco and Collie!

and let the used air blow into a central place like a hallway so the air can scatter around your house.

NEVER vent air to outside directly,it will be visible for police or scavengers with infrared.

 

Just keep an slightly open window ,and suck the fresh air from that room.

Let the air from tent 1 pass into tent 2 then out in your hallway to dissipate.

This will keep temp. and humidity to your spec. with a bit testing you'll get it right.

Then keep adjusting it when necesarry,to summer/winter modus.

 

So yeah ok I choose the tent that is ON at night, this one will not get the loop back, and I adapt to warmer daylight temperatures.

OK

And thank you for the safety trick, Collie!

Other solution might be having 2 small fans and hoses between the 2 tents to exchange air between them.

Takes a little trial and error to get it right, but I see this beeing done a lot.

That's exactly what I do and honestly in terms of temperature stability it's very effective.

The exhaust of tent #1 is plugged to tent #2 and the exhaust of tent #2 plugged to tent #1.

I need to get my hands on a hygrostat that is at least 1.5A and ideally a thermostat 3.5A.

The rooms are sort of barns, not very well isolated...

Hello guys,

This is my first message here, I read as much as possible on Wietforum using Google Translate.

I come from Opengrow where I log as Provence.

I apologize for writing here in english.

I prefer to ask dutch growers for this question.

QUESTION

I have good temperatures in the tents troughout the year without using electric heaters.

The big problem comes from the humidity levels during automn and winter. 75-80% humidity.

Plants can't make evapo-transpiration efficiently so they take longer to mature and last time I lost a good part of my harvest to mold.

Do you guys supply plants with outside air for gas exchange ?

I suppose you use hygrostats ?

What models do you use ?

I'm done with the climate controllers. I've tried the "Step-controllers" Temp+Humidity and I returned them to the shop.

Expensive and real crap. Never worked efficiently. I either had good temps or good humidity, never both together.

My feeling is that at certain periods of the year, I either have to

-give up on optimum CO2 levels in the room or

-deal with too high humidity

I guess someone here already had the same problem and maybe found a solution...

Thanks a bunch for reading

You have an impressive forum and good growers that's for sure
