Grow Room High humidity in flower??

[StevOrganic]

You will be fine I lost 4 colas to bud rot this morning still sulking now but my own fault so shopping for more fans and a new dehumidifier, sucks though 1 of the colas was like a pineapple broke my heart throwing it in the bin

Ah shit hate to hear that man I'm hoping mine will be fine the buds seem to be all evenly sized thanks to the topping and they are more sativa shaped long and thin rather than short and fat.

To follow the VPD chart, I use humidifiers to keep humidity around 65% from seed to harvest in DWC, and have never had bud rot.
I do have good air flow.

Cool man thats great to hear the buds seem to be fattening up nicely can notice the size difference every couple of days.. I'm on day 3 week 6 of flowering and strain is a 56-63 day finisher.

The reason i asked question in the first place also is because ive been following the vpd chart the best I can all the way through and wondering why all of a sudden you supposedly NEED to bring humidity to between 40-50%.. observing my plants they seem to be developing nicely and I have really good airflow in the tent also.

As long as you have good to exceptional airflow, running at the top of the chart works.

Great stuff thanks this is just what I've been looking for there is so many charts and they are all different I like how this shows the environment conditions for each stage of growth.

on the 1.5L v 3L waterings...assuming they need the 3L to wet the whole pot.id rather alternate pot waterings if possible.
nice chart Arthur bit more detail than the thing i have.
lil 6" fans is great £10 Argos 14 watts or thereabouts.a spare,and an extra 1 if yer dry area is not the tent.
high humidity is a house party for budrot/mold.they are pores like shrooms/bacteria so they all around us.they can only breed in stale/stagnant air (a grow tent has corners/buds clumped together,so a micro climate/breeding ground) and the tent is a micro climate itself compared to the room its in,and the house itself.
airflow top/middle bottom of tent.relying on 1 fan and the general suck of the extracter fan this time o year can be an open invite.
keep er lit

Cheers man i have it covered a 7 inch ram fan under canopy and a 6 inch one blowing over the top of the canopy all parts of the plants moving and extractor fan on full whack.. i stuck my hand In the passive intake vent after lights out and air feels nice and cool due to airflow not warm and stale... i can't wait for these plants to finish ive always wanted to grow a jack herer hybrid unfortunately first attempt outdoor my black jack got soaked and ended up with bud rot so for sure going to avoid at all costs this time.

I know where your coming from man thankfully they are undercover in polytunnel thats half the battle but in the mornings the inside of polytunnel is pretty much 100% humidity only had to nip one little bud off yet..

I noticed a couple of dry leafs at top of cola I put it down to my m8 squeezing the bud to hard but then next day noticed on top of other so I chopped all 4 colas of and inspection showed I was fucked, rest of plants fine and took the 4 down this morning. This how tent looks now after a change
