Grow upcoming - plant size and humidity

I usually only grow in the winter because in the spring and early summer my humidities are high in my basement.

I want to get another grow in but it will take me into the spring.

I’m able to control RH by plant size and my dehumidifier. My dehumidifier just keeps up in winter with four plants vegged for 6.5 weeks.

My question is this, what can one expect for yield on average for each scenario below. Also how many weeks of veg do you think I need to keep RH down? Would it be better to just lollipop?

I’m thinking a max of five weeks of veg to keep the RH down in flower.

A) 12/12 from the start
B) 1 week of 18/6 then 12/12
C) 2 weeks “ “
D) 3 weeks “ “
E) 4 weeks “ “
F) 5 weeks “ “

Bigger dehumidifier, or vent outside.

I could tap into my drier vent, it would be a 6 inch fan reduced to a 4” line

Just saying venting outside will drastically lower the RH.

Ok I’ll do that, the neighbors will love me, lol

Humidity increases as temperatures drop. More of a dark period and you're going to have more humidity.

Plants in veg love high humidity if you can keep the temperature up.

You'd be better off growing on a normal schedule to get it to flower quicker and finishing quicker IMO.

I’ve been tossing around an idea, instead of drawing in air from a lung room that’s 65F/18C and 60-65% RH I’d draw in air from outside that’s 32F/0C. Would keep my temps down and lower the Rh more effectively. I think that would be the best way, no?

I'm just saying based on my personal experience. Even though I'm in CO and we have super low RH, I was running a decent sized dehumidifier to keep it around 35%.

I started exhausting some outside, and my RH barely ever goes over 10% now. Actually too low, and I should probably hook up a controller.

Some plants can handle the low humidity better than others.

I hear you, I’m in the same boat, low RH in winter but my dehumidifier is not as large as it should be and it gets a solid workout. I tried pulling the warm moist air out and return air that was passive coming back in at 22% and 65F dehumidifier still barely kept up. Might have to axe a plant or two if I can’t get it under control or try bringing in the cool air. I think I might have more temperature problems than rh with outside air though

Definately by strain...my last grow went perfect with low RH... Im growing 2 wedding cake phenos now, and if i get into low 30s they absolutely hate it
