Peppers I'm growing are a lot less hot than the ones at a store.. Anyone have any idea why? Maybe the packs of seeds I bought from the store are made to be not very hot?
CAPCOM said:Don't water your annuums for a week and then pick them. I have found that stressing jalapeños and Serranos makes them produce more capsaicin. Habs? Water when the plants need it only. Every 3 days sounds like a schedule and feed them good.
I am curious what is the difference between "SEEM hotter" .. and hotterTopsmoke said:you should NEVER let your plants wilt between waterings!! cant stress that enough, the very fine root hairs are how your plant actually receives nutrients. When the soil turns hard it destroys these hairs. (thats why your cucurbits wilt in the midday sun btw, shallow roots) THis also puts severe stress on the cells of the plant which require water to maintain their structure (why your plant droops) and to circulate nutrients (see transpiration). The reason peppers SEEM hotter after letting your plant dry out is because it concentrates the available capsaicin. So your just reducing the water content and stressing your plant. Most peppers are subtropic forest floor plants, just like tomatoes they like constant moisture. Most likely your plants are just too young, My earliest peppers usually have no heat at all. If the plants are potted water when the top inch feels dry and be sure to wet the entirety of the soil all the way through the pot. If outside, peppers need 1in of water a week roughly and mulch will help maintain even moisture between waterings.

I would say that if they seem hotter, they are hotter.. I am just curious because of how you stressed "seem"
here's an interesting study, the findings were that the genetics of a plant determined whether peppers were "hotter" under drought stress. The most interesting thing was that the hotter the pepper the more drought resistant the plant therefore less change when stressed. It did however find that yields were reduced across the board and the less pungent peppers that were effected had low transpiration rates . http://www.chilepepperinstitute.org/content/files/impact_of_drought_stress.pdfspicefreak said:Honestly, I'm not entirely sure that stressing them doesn't lead to greater capsaicin production but certainly more water will make the raw pepper milder without affecting its cooked or dried forms.
the first study also mentions that capsaicinoids reach max levels at 30-50 days after flowering.backyardpepper said:Peppers I'm growing are a lot less hot than the ones at a store.. Anyone have any idea why? Maybe the packs of seeds I bought from the store are made to be not very hot?
This seems to be grouping MOST peppers into a specific group of peppers and to a specific climate. IMO this is not true. While most peppers do grow in a hot climate they do not necessarily grow in a constant (moisture in the root zone) environment. Most pubescence are a good example of this. high altitude, dry and most likely windy even favoring the cooler side of temperature.Topsmoke said:you should NEVER let your plants wilt between waterings!! cant stress that enough, the very fine root hairs are how your plant actually receives nutrients.

This is also what I have heard
this article talks about using nutrient ratios to increase capsaicin production as drought showed no increase for them. http://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=15571
really if you were dead set on using this method to increase the heat, you could just pick the pepper and leave it on your counter for a few days, it will continue to ripen and lose water, therefore concentrating capsaicin and the plant doesn't need to be stressed.
I am not convinced this will have anything to do with increasing heat as the capsaicin present in the pod does not change, and the volume of water lost would not really dramatically change the ration of water to capsaicin content.
my experience is that it does concentrate capsaicin, ripened a bunch of peppers on cut plants, threw off all my sauce recipes because of increased heat to weight ratio. Again my main point was drought stress is bad for plants and personally when i want a hotter pepper i just eat a hotter pepper but the initial question was about why his jappys aren't hot and I said just give them time and not to drought stress them as a remedy.CAPCOM said:I am not convinced this will have anything to do with increasing heat as the capsaicin present in the pod does not change, and the volume of water lost would not really dramatically change the ration of water to capsaicin content.
