Vera,

I would look at with a magnifying glass or one of those hand-held lighted magnifiers that Radio Shack sells in 30X and 100X. Someone here might have a good guess though.

Good luck!

Do not take my post as 100% factual.
There is a growth that you describe that happens when the humidity levels are high. From what little I heard it sounds like it is what you have. It is harmless.
If you need more information let me know.

As munalos said. The name for it is edema, sometimes spelled oedema.

I know about edema...I learned about that when I was in charge of growing my own poinsettia crops while completing my greenhouse degree, however my home is far from humid. My last crops at school included peppers and tomatoes grown in a gh much more humid...50-60%. The humidity in my home is anywhere between 25-40%. I have a good hand lense so I know it's not a pest. Other than this, the leaves/plants are in pretty good shape and this "thing" that is happening is only to one variety. Oh well whatever it is, I guess since their happy it must not matter too much LOL!!
I started the Barney and Pueblo way to early at the same time I started the Golden Hab...Jan.06 so maybe their screaming to get out already. The Barney are already in gal. pots, nice big healthy green leaves vs the slower Habs still in 4". The Pueblo I'm not too happy with...none look the same and they are not very vigerous. I don't believe I will order from Pepper Joe again...the amt. of seed for one isn't worth it for the price and two I want what I order!
