Not a Brain Strain, unfortunately.

Josh

I agree with Josh, not a brain strain. Also skin is too smooth to be a brain strain.

+3, not Brain Strain

This is a photo of my Yellow 7Pot Brainstrain from last year. It shows a fairly large range of pod characteristics on the same plant. Some of which are not unlike the OP's photo. Or, did I grow a U/I plant last year after all?

Yah, seems everything I am growing the last couple years have been crosses. My first few years growing, everything was growing true.

I feel like dumping almost my entire seed collection. I didn't mind a cross or two, but it is getting to be a real habit lately.

On another note, I do have one pod in that photo that looks like yours.

Update here.. ive got dozens of different pods goin on but heres a few

with the brain strain its going ok just been told by the company i bought them off that its normal as tine changes the pods will grow different year to year but the genes stay the same just like growing children...ill save the seeds from these pods and see if that theory is true nexf season and heres a mourga uv that had a accident mid uk season very small pods but doing ok

From your last set of pics those are Red Brain Strain. I grew them last year. Once they ripen cut one open. It should smell extremely fruity sweet. Be warned they are hot, and very potent.
