This is complete nonsense my friend & needs to be checked,im not one to refute others advice but when it's just plain bad advice such as the above it needs checked.
The conditions you state as being bad are as close to a natural growing condition that can be replicated within a enclosed area,infact every expert grower ive read up on highly reccomends air flow into the canopy to keep the plants moving at all times,some well established growers go as far as to strongly reccomend having a constant & steady air flow comming from under the plants at all times.
These pics are of a room with heavy air circulation,the room is 12 ft x 14 ft,in 3 corners of the room are 3 18 inch oscalating fans set on the highest setting,these 3 fans are timed to oscalate at the same time ,which in turn makes the canopy look like a wave on water when the air flow makes its pass,each fan blows from a different height reaching it's air stream into different levels of the plant mass,all leaves are constantly being blown,the 4th & largest fan is a heavy duty 24 inch air circulation fan set to keep temps equal at all levels of the room.
As you can see from the pics the plants are healthy & far from being dried out,these plants have only been foliar fed one time 2 weeks ago & have never been misted with plain water.
Oscalating fan #1 set on high.
Oscalating fan # 2 set on high also & digging deeply into the canopy.
Heavy duty air circulation fan set on low,this fan will increase in speed durring budding until its on high mode,the oscalating fan in corner # 3 is not shown.
Healthy canopy being blown in heavy breeze 24/7 for 3.5 weeks straight.
