New Grower Two questions.

target rh range is 50-70 % 30-40 is low... what you're looking for is the range where the stomata open and allow transpiration... plants need to breath to grow... so too dry n they close up (like us dehydrating and stopping sweating) and too high and they can evaporate enough and molds and funguses grow easily...

Ok, but at what % does the stomata open?

I don´t want to blast that full power, becouse i´m afraid i´ll get mold. That would be real sh***y.

no exact set %... but the 50-70% is the safe and efficient humidity range to hold.

I usually try and keep mine between 50 and 60, at the minimum.

A lot of autos strains don't produce amber trics, so that's not the most reliable method to use on autos. I prefer to go by the fan leaves. Here's my theory: https://www.autoflower.org/f44/when-harvest-autos-your-leaves-will-tell-you-4889.html

The only real way to see if they are ready is check the trichomes,I prefer them all milky with just a few turning amber.

I have read that, and i use that more then watching the trichs. I do that also with a microscope, but i find it a lot easier to go by the leaves. I think i´ll wait a few more days. I don´t like it to have too much "stone" anyway.

Thanks guys.
