Help hot temps 35-37 degrees Celsius a problem ?????

Hey trail.. Thanks for the info .this video.. Is a great knowledge ..now I understand why my OG KUSH is not growing the way it should be.. Jorge says that if the temps go above 29 degrees Celsius than the growth slows down 80% ..if that is the case then my Og is behaving like this cuz of heat..... Inspite of give enough water heat can slow the growth??
 
I am a bit late in this thread. 35-37c is in the shade I guess? So you use shade cloth to reduce the afternoon sun.
These temps are not ideal to grow fragile seedlings, especially autos. Next time when growing in the hot season, use a humidity dome. This will keep the seedlings leaves nice and humid as they like it.
The humidity dome will also reduce the temp by another 5c.

A humidity dome should be 95% size of your pot size and made out of clear plastic or glass. A transparent fish or salad bowl is ideal.

Good luck.

So ideally.. Is it possible to grow autos in this kinda climate. And also I am using 50 % shade cloth.. When it goes to 35 or above.. the heat is cut almost upto 3 to 4 degrees.. So practically my ladies get the temps around 32-33 degrees... For 3 to 4 hours with shade cloth on.. And with out shade the temps it gets is around 31-33 degrees.. Cuz there r lots of people that say these temps are pretty OK for cannibis.. I am not sure about autos...

Can any one put some light here on this.....
 
30c+ is too much for seedlings but use extra shade cloth and a humidity dome(will fog up and filter some of the heat too). While they are small, can you place them somewhere cooler. Once they around day 21 they can take a bit more heat but you need to keep up the humidity until full in flower, then they can cope with the full sun. Avoid stagnant air flow as the plants will suffer in the heat.

I assume your heat is dry?
 
Yes it's is kinda dry... It's day 25 for OG kush.. And it still looks small.. Plz take a look.. image.jpgimage.jpg
 
U think it still need the humidity dome.... And also my other lady is in its veg stage.. Doing great.. Plz take a look image.jpgimage.jpgimage.jpgimage.jpg
 
I am afraid that you have stunted them all. Never use tutes till day 14 and then very weak. Also is your soil PH within range? Best not to transplant or upset the roots or your plant will stunt.
I would grow them till finish and learn from your mistakes.
 
your soil also looks very dense, try next time to use a fluffier soil. Also make sure no nutes till the 4th set of leaves come! the seedling has plenty of food stored in it for it's initial phase.
hope it turns out alright! ya other girl is looking good though. i'm sure if you had some nicer soil they'd be huge!
 
It seems the bigger plants are growing in a red colored soil and the Kush is in darker soil. Are you using different soils?
