sun How much sun?

Yup with my mix of mushroom compost,vermiculite,Garden Soil, Burpees tomato and veggie fertilizer I now have to let it completely dry now than before. But I am gonna try to stress them out so to get hotter peppers.
 
LOL.  Good luck, because that's kind of a myth.  Keep your plants well fed and watered, and enjoy a bounty, rather than a unicorn.

I have a question regarding the amount of direct sun that plants should be receiving.
 
I am in Zone 9B.  All of the original research I did when I first decided to give pepper growing a try this season indicated that they should recieive full sun.  I started with the following seven peppers
 
1 Ghost Pepper
2 different Jalapenos
1 Tabasco
1 Thai Hot
1 Habanero
1 Dragon Cayenne
 
They are container grown on my pool deck.  In their original spots, they received direct sun (albeit slightly diffused through a pool cage)  from about 8 AM till 5:30 PM.  All grew well except the the ghost.  It seemed to be a bit sunburned so I moved it twice.  It is now thriving in indirect light with about two to three hours of direct very late in the day.  The habanero also started showing some stress.  It now gets about 4 hours of early morning sun and is doing great.  
 
I harvested a goodly bunch of jalapenos off both plants a couple of weeks ago but noticed over the last couple of days that both have aborted some pods.  Our daytime temps are hitting 90 already.  The cayenne is thriving and producing great.  The tabasco is the picture of vigorous health and is just starting to flower.
 
Long way around the barn but here is my actual question.  Is there a rule of thumb, given my locale, as to how much sun certain species need optimally or is it just a situation of keep moving the plants around to find each ones sweet spot?  I can pretty much accomadate any needs just by changing locations on the deck.
 
Any input from you experienced guys is greatly appreciated
 
I'm in the same zone as you.  Full sun, all the time, with the exception of rocotos.  They really don't seem to like it here, but I can manage in part shade.

Which myth? The one purported by these scientific studies?> Scientific Observations of Environmental Stress on Pepper Varieties

What's wrong with a unicorn? They are beautiful and unique! If someone wants a unicorn they should be scorned?

LOL. kind of a myth? Saying ''kind of a myth'' sounds like that you're not really sure if it really is a myth or not. Next time to be sure for you, that it really IS a myth and you can confirm it. Oh i really am going to enjoy my bounty. Now next time be sure that you do know and for a fact that it is a myth or not. I am not interested in a half truth. I am interested in that it is either a plain myth or a plain truth. But I do take these with a grain of salt.

Stressing is only shown to have a small effect on plants of the lower capsacin varieties. (like under 10,000)

You're a new guy in here, asking very noobish questions, and then chastising me over pointing out something that has been discussed over and over and over again...  Sorry man, that's not cool.  Search function will show you what I'm not going to search for.
.
If you like stressing peppers, and you feel it's the way to go, knock yourself out.  Be sure to browse the pepper porn that some of the hydro guys put up, who NEVER stress their plants.

That very study concludes that not all peppers are affected by drought stress.  Different "pungency" levels are affected differently, with "high pungency" unaffected altogether.
.
The big difference is that this study shows no actual numbers to measure capsacinoids.. Other studies do.  Others that have been posted right here in this very forum.

Hmm. ok then i won't stress the peppers then if it won't really do anything. I really didn't see anything about it being discussed over and over again. I just call it like i see it, that's all. Of course I am going to ask very noobish questions since I am the new guy here. But now that i believe you on the stressing part I'm just going to water everyday since it's hitting the upper to late 90's.

Come on S7, catch up! Water Deficit Affects the Accumulation of Capsaicinoids in Fruits of Capsicum chinense Jacq. 
`
Both water stress treatments led to a significant increase in the concentration of capsaicin [an increase of 16 mg·g−1 dry weight (DW) with respect to control] and dihydrocapsaicin (19 mg·g−1 DW increase with respect to control) in the placenta of 45 DAA fruits.

One single variety of the "less pungent" varieties.

It's not me that needs to catch up...  Somebody else needs to learn to pay attention to details.

Probably the fact that you're busy posting so many links, but not necessarily reading or understanding them.
.
the article said:
Previous studies have reported that capsaicinoid content increased under drought stress (Estrada et al., 1999). However, in our study, the significant increases in capsaicinoids were observed only for the low and medium pungent cultivars but not for the high pungent cultivars.

.
And like I said, there are yet other studies which have been posted on this site, which further quantify the extent (or lack thereof) of drought stress on pepper plants, and further clarify the "pungency" issue. So, yeah, I feel fully confident in standing behind the statement that it's "kind of a myth". Unless you know better. By all means, this is a discussion, so discuss...

I thank you for backing it up with facts.
 
If you read the paper fully it states that the reason the high pungency peppers didn't get an increase in pungency from drought stress was because they are more resistant to the drought stress and that more research is required to draw a conclusion as to why
 
The low and medium pungency cultivars got a reasonable to high increase in pungency
Calling it a myth - a widely known but false idea - it incorrect
 
Codeman for my 2016 season my plants were water stressed and my yield was appalling. The biggest issue I had was that I used coco coir incorrectly and as a result my pots had uneven water retention which negatively effected the root zone.

For my 2017 season I changed my potting mix to one that stays moist but still has good drainage to prevent going soggy. And WOW I picked LOTS and LOTS of fruit :) come to think of it I'm still getting pods nearly six months after my first ripe ones lol

My advice would be treat your plants nice and get lots of fruit. They will be hot, reducing your yield to increase pungency doesn't seem worth it to me.

It doesn't really matter why.  Like it doesn't matter how or why gravity works.  The result is still the same.  There are other studies that back up, and further quantify the findings.  I didn't say that it's a total myth, but it's not 100% true.
.
You're a smart guy who loves a good fight discussion.  I challenge you to prove or disprove what I say.  I've already taken the first steps.

Water based on soil moisture condition, not a set schedule.  Check the soil daily and water as needed, over watering plants is the number one cause of lost plants.

well... you kind of need to when it is 100+ degrees for 100 days straight. I hate summers here.

+1

Your plants and feel of your soil, as well as the weather forecast will tell you when and how much to water. Takes a little while but eventually you will get the 'feel' of it and it will become second nature.
