FEEDING: ... 3 litres per plant
COMMENTS:
Watering now up to 3 to 4 litres per plant, per day.
So there is over 40 litres of water being put into the tent every 24 hours.
No wonder I'm struggling to keep a hold on the humidity!
It means I've had to make a decision which isn't ideal.
My biggest fear, especially with Team COB being so lush, is mould.
If i want to minimise the risk, I HAVE to get RH% down - I can't have it creeping into the 70's - not at this stage of the grow.
This means I have had to switch the extraction on 24/7, in an effort to keep the humidity at a level i can live with until I work out a more permanent solution.
The trade off has been tent temperature.
It's winter.
With the extraction on 24/7, it means there is cold air being sucked in to the tent continuously
Temps have dropped from a constant 24°C to a constant 21°C, but at least humidity now is around the 55 to 61 RH%
That's not where mould likes it, but it is still a factor if I can't get the RH% under 50.
It's also the main motivation for the defoliation haircuts.
Ideally I want the temps UP to around 26°C, the humidity DOWN to around 45 RH%, and loads of air circulation.
With current climate conditions and watering requirements, that feels more like Mission Impossible.
But hey, if it didn't test us, where would the fun be?

Awesome grow...simply awesome! Regarding reducing the moisture, how about:

This is a battle I'm losing on multiple fronts.
Temps are too low and humidity is too high.
That is the "perfect storm" for mould.
Welcome to winter in a basement.
That aside, the tent is looking good.
The A vs B experiments have been well worthwhile, even now mid-way through the grow.
There is a distinct difference between the COBs and the CMH lighting.
The other thing worth noting is how the COB Non-ScrOG girls have bounced back from their haircuts. They are back to their pre-haircut hirsute magnificence. Damn near impossible to believe they even had one!
I'll let the photos do the talking ...
