Hot temps=low yeild?

So i have a great question that needs to be answered, which may be followed by a few more Q's thereafter...

Q- I live in one of the hotter states, but grow inside... although the A/C isn't on 24/7 it is roughly off for about 10 hours during the hottest part of the day to save energy.. Temperatures have gotten as high as 106 in my box but consistently around 90+ when the Unit is off... will this significantly reduce my yield??

Here are a few pictures, my girls are roughly seven weeks old, they were burned badly in the second week of growing due to bad MH light placement but are recovering well...

any answers, comments, questions are greatly appreciated.. I NEED HELP!

(as you can see the bottom leaves had some heat stress issues, there were even worse ones but they are long gone and cut off)

I would recommend grow sativa dominate strains as they are from around the equator so they are more adapt to higher temps.

In general yes higher temps will negatively affect your yield.
 
Papaya.. -is the fruit of choice..It is Indica Dominant
>>The Temp is consistantly around 75-78 degrees, with some good fan distribution.. but does ranch from the high 80's to lower 90's. . .
>>>The Area has been re-constructed to me more ciculative


* im thinking about low-stress-training as well seeing as Papaya stays short and dense, making it very suitable for a "Sea of Green" garden

Any comments on or recommendations??

as long as you have very good air flow and exhaust heat don't matter.. its the ols hot ass stagnet air that is bad on the forming of the buds..
 
Thats great to know, thanks for your constructive responses..
>>i was Wondering, is 8 inches too low to start flowing? i have around four feet in height to work with, and my girl is at week seven right now...
So i was thinking i'd let her grow a few more nodes, she has about sixteen larger branches right now, and is a very bushy plant

So i was just looking for a little advice on when to flower this girl(Note The pictures)

Also i was wondering if week 7 is too late to be doing LST to the plant, what do you guys think.. counterproductive at this point? Seeing as i still want the plant to get a little bigger/bushy... HELP fellow GREENthumbs!
p.s. I've been watering the foliage quite frequently, when the temps are cool and the lights are just firing up, will this speed growth/helpo the final yeild???

hello,

yes you can lst at week seven, you can top it, super crop it or do what ever you like. you can also flower it it you would like, but if you have the space i would let it get bigger. foliar spray is fine up until a couple weeks of flower, then it can rot your buds. are you using nutes in your foliar spray? or just straight water? are you nuteing them at all?

hope this helps a lil

sorry but i have to disagree. before i got AC hooked up in my flower room i was exhausting the air almost 3 times a minute. but when the air you're pulling in is 90+ it can only do so much.

after i switched to an AC box i noticed substantial increases in growth.

well thats true if the air outside is hoter then iondoors thats going to defeat your purpose..

so if heat is not an issue, and fresh air solves the heat issue, then at what point does the heat become a problem. it has to some time regardless of airflow, probably between 90-100 for some strains and probably higher for others, obviously, otherwise the outdoor crops wouldnt grow at all in the late summer.

i am not necessarily disagreeing with you my girls, i feel that you are right to a point, but only to a point. but then again, your credential speak for themselves. anyways, just trying to keep the topic going.

106 is to hot. they look fine now but it will catch up to you. I say put in vent fans. push it out to somewhere where the heat disipates

usually if the heat is hotter outside then indoors you vent to a into your living space. Which should be cooler and you will suffer and may have to crank the air conditioner on a bit more

the heat becomes a problem if it is consistently at 83 and above 85 is not where you want your plants to be living in comfortably you'lll get spidermites

What kind of light are you using?
You can make your own cooltube for pretty cheap. There's tutorials in the DIY area or google "home made cooltube".
It's the best help for high temps in small areas IMHO.

actually i change my mind. your plants show heat stress. lower the temp via the fans i said the exhaust fans into a cooler room
 
Yes yes, i have two PC fans crafted into the left side of the box, one at the very bottom, one at the top
>>Along with about a 12 high velocity honey well fan pointed at a 45 degree angle to push hot air out the top of the box(which just last week removed the top) and now the light just hangs down with its reflective shade giving much more room to escape than before--about 2X2 feet to espacep now, before it was only about a 3X$INCH hole where all my cords to the lights ran through for ventalation. to go along with the velocity fan i have an oscilating fan blowing between their leaves and underneath where the stems are...When you place a hand in the are now, w/ AC off it almost feels like a personal AC, they are looking much better, but am still concered on when to flower...

you can lst the plant as long as its not in flowering due to stress and as long as its not to thick of a stalk thats a risck of snaping the stem
