buds humidity and ripen

What week are these in? They don't look anywhere close to needing to ripen yet. Humidity with those plants and that airflow 50-60% easy for the next few weeks they are in no danger of bud rot.

3rd week into flower and the humidity went a little higher than 60 but I invested in a dehumidifier so I’m hoping for the best . It’s currently at 50

50% RH or lower in bloom, make sure you have air movement both high and low

Hey @Ecksrdz , the temperature, and humidity are related. You can use this calculator to find your VPD. Recommended VPDs range from about 0.8 when you are propagating and 1.6 for flowering. Depending on your humidity sounds OK. It is my understanding that VPD is considered the "special sauce" and once you hone in your values, you will be able to produce a consistently good quality product.

And @Beachwalker's advice is good. Since cannabis is a dicot, it only has the stoma on the bottom side of the leaves so air movement is critical. Good luck :)

Is there charts on this site to compare with the calculator..ive actually bought an infrared thermometer but unsure on its accuracy.id say the accuracy is very important even if 1-2deg out? Crap pic .lense is scratched to shit

I did a write up of a collection of info on VPD. In there it gives ideal kpa ranges for stages and explain more of how the plants respond to it.

The problem with chart is you need a new one for every different leaf temp variant so you would likely need like 20+ charts.

VPD (vapor pressure deficit)

Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...

Very nice site ya got there. Great info hoping a few more calculators like cooling for grow rooms etc in the future

Cool . I will read it tomorrow .i think i remember seeing that little while ago..im all plum tuckered out lol..nanoo nanoo..

Always working on new calculators. I will think about the cooling for grow rooms but there may be too many variables. Any other ideas just let me know!! :-)
