My system is setup to keep the humidity in the flower tent ~60 65% all the time. But I do have 3 fans running in a 5x9. The exhaust fan trips either from temp or RH greater than 67%, so with that plus a dehumidifier it stays pretty tight.

How do you like the larger reservoir? I went to a 65g which was 14-20 days and I love it. But the hard lesson I learned was I had to watch PH drift especially in the first week after mix. If I decide to be super lazy I will add a two pump doser. Makes vacation an actual possibility.

I’m diggin the 27g reservoir, I can go easily 2-3 days without touching in veg but when lights are on for veg water is consumed way more that in flower, now that it’s in flower with less light my ph is dropping daily less water is consumed and I’m noticing a drop of 80-100 ppm per day and ph drops about .2-.4 point per day. I will reset the whole system this weekend with a flush and purge.

They are taking off, and I managed to create heat stress on the right side with my Ozonator. But over all she’s looking good.

Ph was 5.6 before added well water to bring it up to 6.1

Temp 74
Rh 58%
Ppm720

Just purged the system. Ran a constant flow of fresh water through the whole system including the roots and purged it all out. Filled her back up with H202 dilution. ph 6.2 before nutes.
After nutrients water measured:
Ppm: 1000
Ph: 5.8 stabilized at 6.2 after 20 mins. Should be perfect as she consumes nutrients ph should go down.
Water temp :68F/20C
Room temp :70F/21C
RH: 55%

PH this am 5.8 ppm 840 did some defoliation underneath canopy, trimmed a few fan leaves.
8 hrs later water down to 5.6
Emptied some water out and refilled with alkaline water added nutrients. After stabilization water is
Ph.6.0
Ppm :780
Water temp 69
Room temp 71
Rh 56%

Just check ph .
Ph dropped to 5.6

emptied 1/4 of reservoir added alkaline water and peroxide.

After exchange before added nutrients :
Ph 6.2
Ppm 590


Added nutrients water measured after added nutrients :
Ph 6.1

Water temp 70
Room temp 71

Looking good man!!

I'm wondering if they can handle more light? Anyone else thinking this? 10% increase?
Yes I wanted to see what the PPMs were like after I raised the light. Will be extrapolating the ppm consumption in relation to the light intensity

Just checked ppm and ph before adding nutes and h20, h20 in res is really low so I am assuming she’s drinking a lot of water more than nutrients at the moment, assuming she’s trying to get volume today or the lifting of lights is tell her to stretch more idk we will see tomorrow!

Before change of water
ppm 830
Ph 6.1

after added h20 and nutes
Ppm 700-710
Ph 6.2
Water temp 70F
Room Rh 50%
room temp 72F

"assuming she’s drinking a lot of water more than nutrients at the moment"

Imo even 700 is too rich.

For reference I have a 4 site current culture on day 13 ppms are at 410
