Droopy seedling after topping - can she be saved?

Use the leaf temp, not the air temp on the VPD chart.

You get leaf temp using a temp gun?

 

[chaduranga]

According to the vpd chart everything is perfect. I have good results ignoring the vpd chart and keeping the room at 82f.

During the entire grow or just flower?

During the entire grow or just flower?

From seed until late flower.

From seed until late flower.

What rh do you keep?

 

[chaduranga]

Quick update. 8 hours after feeding. Slight improvement.

Use a decent infrared gun.

What rh do you keep?

Usually 40-60.

We use a no-touch thermometer.

lol, what a waste of money. you don't need a infrared gun. Just hold your hand on top of the plant for 10min and you'll know how hot it gets. or even better just get your RH up to 60's and keep temps around 80/82f. Those hurten leaves are not coming back, instead focus on the new growth.

My turn to laugh now. What a tool.

It's Thermometer Man!

that aint what you said. So indeed, what a tool

 

[Pushrod Monkey]

This fool ^^ can go to work here hand sensing temperatures in 10K square foot grows. Shut up, fool. But you'll keep your ignorant jaws flapping. Won't you?

 

[PK1]

lmfao! go get your medication and stop monkeying around and if you can't keep your self respect then keep your comments to yourself.

I think the infrared guns are a great tool. Leaf temps are affected by room temp, humidity, light spectrum, barometric pressure, and probably the moon cycles. Knowing the leaf temp can help dial things in. That said, the guns aren't that accurate. 78 in my gun might read 75 on yours. You just need to experiment and see where your plants are happiest.

i'm not saying its not a great tool, and you are correct it helps alot when you really need to tweak and dial everything to max performance. However, for a 1st time grower that has already spent tons of money getting the gear together is not something that i would recommend. plus, holding your hand on top of the plant for 10 min gives you an idea of how everything is. Wind flow, light intensity heat and so on.

The hand test works for hps. With my leds the hand test would kill my plants.

I seem to get the best growth in the high 70s - low 80s.

LED can not be tested with your hand and, the nerves in your hand are not sensitive enough to accurately determine temps. If they were, Doctors would have no need for thermometers. When you can afford it, get a no-touch thermometer.

Marijuana plants like temps between 74-79 with lights on and 60-65 lights off. This is well known.
