Germination times may vary from one variety to the next. Some varieties can take up 4 months but that is rare but can happen if you can wait that long without giving up. We have a small list  of varieties and average days for germination at the bottom of this page. But first the basics: 

All varieties benefit from warm to very warm (80-95F) temperatures.


Our germination process at Atlantic Pepper Seeds:

Germination Method #1

We use small containers usually prescription bottles which we buy from a local drug store. We mix 9 parts water to 1 part 3% hydrogen peroxide. (this is to kill off any bacteria, and we add a very small amount of baby shampoo to help cut through the oils on the seeds, We do this for the first  24 hrs. The next 24 hrs we use fresh water with a PH of 6.8 to 7.2 mixed at 15 parts water to 1 part hydrogen peroxide, We keep the water temperature at 85F to 90F and we like to keep seeds in the bottles till we see sprouts changing the water every 24hrs. 

We use Salt Peter (Potassium Nitrate) for the hard to start varieties with a mix of 1 - 2% salt peter / 1 gram of salt peter to 100ml is a 1% solution for a maximum of 24 hrs. This help soften the seeds shell and help them to shed the shells once they start to grow. This is also a must for wild varieties. This simulates passing through a birds digestive tract. We would sell Salt Peter but you need a License to do so. So here is a link to where we get our Salt Peter. They ask for the reason you are trying to buy Salt Peter and you need to say for seeds Germination. Here is the Link Salt Peter (Potassium Nitrate)

Germination Method #2

We also use paper towel in bags method with good results as well. We put seeds in between folded paper towel after a quick 2-5 min soak in 3% hydrogen peroxide then mix hydrogen peroxide and water at a rate of 15 parts water to 1 part hydrogen peroxide and then soak the seeds and paper towel. Than place them in lunch bags and seal them. Then place on heat mat at a temperature of 85F to 89F. We change water after one week with the same mix of water and hydrogen peroxide. This can be hard to do. So we more less just add the new water mix to the bags using more then needed and pore off the excess.  

Germination Method #3

We have done this method with good results as well. We put seeds in paper towel in the lunch bags and add water treated with salt peter at 0.5 - 1% (to soften seeds casings) and hydrogen peroxide at 9 parts water one part peroxide. Leave the seeds in this water mix in the bags for 24 -36 hrs with the bags on a heat mat set to 85F to 90F. After 24 -36 hrs we plant the seeds in our starter trays which are on heat mats as well set to 85F To 90F. We will use this method when we are in a hurry or if it’s getting late for Germinating seeds.

We have turned up our heat mats to 90F to 95F to Speed things up a bit. This works very well and will take Days off Germination but this is very risky and can Cook Seeds. This should only be a last resort and only if you have extra seeds because you can lose seeds this way. This needs some practice to do. To not lose seeds. but can be done well if you have some practice at it.

All varieties don't do well in acidic soils, for that reason we like to start in Rockwell and then transplant to soil after seeds start to have first true leafs.

Now for estimated germination times under optimal conditions:

For Capsicum Annuum germination can take anywhere between  1-6 weeks with 2 weeks being the average with some varieties taking 4-6 weeks

For Capsicum Baccatum germination can take anywhere between 2-8 weeks with an average of 2-3 weeks

For Capsicum Chinense germination can take between 2-10 weeks with an average of 2-6 weeks

For Capsicum Chinense germination can take between  2-12weeks with an average of 2-4 weeks but there are some varieties that well take 6-10 weeks

For Capsicum Eximium germination can take between 3-12 weeks with an average of 3-8 weeks

For Capsicum Frutescens germination can take between 2-8 week with an average of 2-4 weeks

For Capsicum Galapagoense germination can take between 2-10 weeks with an average of 2-6 weeks

For Capsicum Lanceolatum germination can take between 3-12 weeks with an average of 3-8 weeks

For Capsicum Praetermissum germination can take between 3-12 weeks with an average of 3-6 weeks

For Capsicum Pubescens germination can take between 3-14 weeks with an average of 3-6 weeks Manzano type peppers usually take up to 2-3 months to germinate under ideal conditions.

For Capsicum Rhomboideum germination can take between 3-12 weeks with an average of 3-8 weeks

Now for germination times by varieties, with the first numbers being 25% germination, second number being 50% germination, and last number 100% germination. This is what we have seen here at Atlantic Pepper seeds and these are rough estimates and can vary depending on conditions.

Good luck with your Peppers and Happy Growing from us all here at Atlantic Pepper Seeds 

A Germination Test we Just Did on seeds from 2016 and thought we should share. We do this every year with most of our seeds. That said we also grow from our own stock so we see our Germination averages. Here what we did to test the seeds. We use the paper towel method with heat mat set at 82F To 85Fwith just Water And Hydrogen   peroxide mixed at 1 part Hydrogen Peroxide to 9 parts water and then count the days to 100% Germination. Here is the one Test and pictures and total Days to full Germination was 7-Days with this Variety which is very good we don't see this that often most will at least take 7 to 12 Days. But the seeds are only 2 years old. This is a testament to fresh seeds.
