Couple of Follow ups. What is a “WPM” and how did that summer grow turn out with the high humidity battles? Can you share the vpd chart?
No, I do not have a dehumidifier. Probably wont invest in one either unless I ever actually develop it. I totally am on the same thought process of playing with temps. I am scared to get too close to that 84F in case it climbs on me. I try to stay 78-80F max all the way in the lights on period. I do have a few more upward degrees to play with though. I don’t want to get too hot thought and and kill them.
I have the lamp at 24" right now on average between the 3 above the tops and I am blasting max 168 watts at them off this 135 v2 board. The only way to bring up the heat is to lower the lamp on them.
I have had the lamp at 20" above them so I can lower it a few inches I think. I will probably clamp one of my fans lower on my 96" shower curtain bar I got vertically mounted in my grow box.
I think condensation happens a 100% rh.
Or more. My understanding is a balance or breathing through the leaves and water uptake from the roots. If air humidity is to high this process is out of balance. So,physical dew or water isn’t really necessary to cause a problem…I am way a rookie here…iv not finished my first grow yet…lol…but these guys don’t seem to send you into paranoia…lol…for fun anyway…I feel your paranoia!!…beleive me!
Iv not had a problem yet listening to what they recommend.
condensations occurs when or at dew point should be a chart some ware . at different intervals of temps to rh cause dew point hence condensation … i think lol happy growing
Nope, never had but rot, neither have any of my local grower friends. I did get WPM once in my beginning days of indoor growing when I used to turn off the exhaust fan at night.
Good to know. What kind of Range in Flowering RH inside your Tents do you normally see without worry? In flower.
I see your Tents you have Scrogged are tight but I believe you are growing in Coco now.
Do you still remember that RH range you commonly encountered back when you grew in Dirt?
I ask. I know we follow similar weather patterns is why I am curious.
I gave my plants a stare down from a standing over looking down view Point. I think I need to be able to see down thru center better, so I feel a lighter trim is in order on mine. I had a suggestion to move a fan further down more towards floor of closet too. Going to trim the centers a bit tomorrow on the 3 hopefuls I am trying to finish strong on.
Sorry about providing weekend entertainment over here on your thread going gonzo and multiple posting. My only excuse is I was extremely stoned.
My flowering tent ranges from 50-60RH with the constantly moist coco and mesh grow bags I currently use. When I grew in potting soil with plastic pots it was more like 40-50RH during flowering.
Defoliating larger fan leaves can help bring RH down a little as well, with the less transpiration and better airflow thru the plants.
Not normal for leaves to do that curling up and dying thing, but newer leaves look good, so it may have gotten over whatever the issue was that caused it or it’d do that to the other leaves as well.
I know this post goes wayyyy back, but I’m new here and I’m starting to dig through every post of your journal. I am experiencing the yellowing tips on my new growth. I know you said its completely normal for it, but I was just wondering if you could elaborate a little more on that if you don’t mind, sorry I’m trying to absorb all the knowledge I can… I’ll drop a pic to show you.
Ahh ok, its definitely the lights because I’m running around 45-48 dli at the moment lol, for nutes I’m using Jack’s 321. I greatly appreciate your reply.
happy growing
