Mephisto Genetics Phrysbeaux First Mephisto Grow

[Phrysbeaux]

The Sour Crack seems to be liking the increased nutrients. I also tried adjusting the humidity in the grow tent, it had been hovering at 20-23% with the vents open. I shut the vents and it bumped up to around 55%, however the temperature also increased about 8 degrees to 86 f. Hopefully the increased humidity will offset the higher temperature for the grow. Any thoughts on this?

Humidity/ Temps ..... Veg state I Rwanda Break in the 78-82ish range with RH around 68-75% - kinda like a sauna..... as she got older I decrease humidity to 65-70% and then came preflower and 60% on humidity and temp still 76-78 ..... Now she is in flower I’m lowering humidity, working in the 59% range right now with temps 75ish .... as she flowers I lower humidity some more to get to 45ish range ..... I follow a VPD (Vapor Pressure Deficit) Chart I found here on a post and printed out, so I don’t have the link but here is a link to Wikipedia quick explain of VPD https://en.m.wikipedia.org/wiki/Vapour-pressure_deficit ....

Your temps RH inside tent NOT good for babies, your more in a flower temp range, especially on humidity side ....

so I thought this
55% max 72 degrees
82 degrees min 70%

@slowandeasy 's suggestion made a lot of sense to me when I read it, and I imagine that the root system will reflect it when this grow is done.

Yes, I am not sure why people water right by the stem. Roots seek moisture. Watering right around the stem gives them no incentive to grow, the roots will remain thin an small. Watering around the edge gives the roots incentive to seek moisture and branch out. I have taken Thousands of clones over 20+ years. I know a thing or 2 about root development. Good luck.

Do a search for VPD and you’ll get a chart that marries temp / humidity levels .... VPD = Vapor Pressure Deficit .....
