Heat. Just read some Ask Ed this weekend. Days over 85. Even though the plants can live, and even thrive in high heat, 90-100+ make for stringy plants... like Sativas. Maybe the real 'changes' to the land-races that we know.

Bad light makes them 'stretch' but, bad light will give you airy buds... but bad, airy buds to boot.

Stay cool, stay safe.

I had heat issues this last run and it definitely dropped my harvest by about 25%, I did not get the tight buds like I did the previous run.

I live in a tropical climate and the above is right. The main cause is heat. We can grow some nugs the size of your fist but they are gonna be foxtailed if its a good strain. Otherwise they would die of mold most likely. I've never heard of bad light, but if the light is to far you can also get airy buds.

hi, darth, i agree the heat can cause this but placing your light too far above can do it too. the tops stretch towards it.

nutrients with ammonium and urea based nitrogen forms airier, more stretched out buds. use nitrate form only during flower.

a weak nutrient dose in flower will do it.

later

cause for airy buds

IMO the cause for airy buds has been overcrowding. My last grow was cool - about 70 to 75F but the plants were crowded.
They grew tall and stringy with airy buds.

I think it's the plant itself. I've had crops (that were all one strain) and had airy budded plants, right next to it's thick tight giant bud sister. So it may be heat, it may be poor lighting, or it may just be shit luck...

I read somewhere someone mentioned that any stress will stunt growth. Anyone believe deficiencies can create plant stress that contribute to this? And is temp itself the issue, or rather stress, as the result of high temps? Just wondering if staying as stress-free as possible would contribute much to correct the issue.

Thx all!

In my experience...heat is a big one...also the strain. sativas are good for this...cutting early as well a mostly sativa strain would need more then a regular 8-9week indica strain. mostly sativa strains have gotten nice and nuggy if given the proper time to mature for me. sativas are a bitch.

As far as "room temps" go. I would take a temp reading from the top of my canopy.

For example, the top of my canopy is 79f. But my room temp is 75. I get my canopy temp up to about 93 with co2.

Sativa genetics will give you airy buds. But don't despair because they will light up your brain. A lack of light especially on lower budsites will give you airy buds too.

sativa genetics with high temps... some strains are also just real scraggly

ohh yeah, the larfy buds are from lack of light as well/ penetration in the canopy
