Need to be transplanted or what??

What’s vpd?

What’s vpd?

Vapor pressure deficit... not to worry you don't wanna go by that with co2 anyhow. Temls 80-84f and 50-55% RH should serve you well.

With co2 though right? Without I should run the temps cooler?

Yes cooler and higher RH. It's the leaf tenls we worry about. 77-80 work well for me.

 

[Nameless_fcuk89]

77-80 with co2 supplementation right? but if I’m not using co2 lower temps at like 70-75 are better? Also what ppms do you use when in veg?

Without co2 75-77f leaf temps.... this usually translates depending on lighting type used and how much IR it contains to about 80-82f.

But many things affect leaf temps... honestly imo air temps mean nothing... plant and leaf tenls mean everything

A cheap IR temp gun eliminates all the guessing. Make sure your using the proper distance when taking temps.

I have 2 650 watt hortibloom leds with the uv & ir bars. So how far should it be from canopy? And I thought it was only good in flowering?

The UV won't do much...its UVA but the IR can affect leaf temps... like I say way to many variables that affect leaf temls so of you wanna get an absolute then an IR temp gun is needed.

Also under LED you can use a lux app in the phone to check... its crude but works.

I use light meter by my mobile tools dev when I wanna check.

Generally speaking 15-45k veg and 40-65k flower.

Always start low and work up.

yea they need to be transplanted maybe giving some light nutes

I venter to guess ph imbalance in root zone

 

[Nameless_fcuk89]

I’m only using co2 at about 7 800 during veg... so should I still run humidity at 50%?

50-60% should be fine at that.

 

[Nameless_fcuk89]

Ok cool and what’s this app your talking about to measure the light?? That’s sounds so dope... I was actually just about to order one on amazon.

 

[Aqua Man]

Light meter by my mobile tools dev. There may be a newer or better one but it's the one I use. If your on iPhone you may need to find another.

Yeah I’m on a iPhone but how do you even read flux, I can understand ppfd readings? Can you convert flux to ppfd?

Make sure you select the closest spectrum.

Hell yeah... thanks bro.

Yo I have one more really dumb question if someone could pls help, I’ve tried looking this up but can’t find anything. So if I’m hand watering rock wool do I need to still add air stones to add o2 to the water?
