This is really a subjective question.....
Like RM3 can be used as an example. There are things out there that you will most likely never get to see or try.....YET, there are some serious, serious beans available too. I'm afraid some of them are going for hundreds and hundreds of dollars for 5 beans!
Real GSC is available and some of the X's by a certain breeder are off the hook.....at 5 Ben's for 5 beans you had better be serious about growing......It's the breeding potential that drives the price up, along with the rarity of the REAL thing........I mean GSC has SOO many rebuilds out there and THAT'S what your buying - NOT the real deal....
Real rare strains/pheno's/cuts held tight..
P-91
Hogs Breath
Blood Rose
"Black" Russian (so dark it actually looks black)
Dbl purple doja
Certain cuts of Chemdog
TRUE (good pheno's are rare) Attica cut Trainwreck
Apollo 13
Giesel
4x Sour Diesel (sadly, this could be extinct)
You get the point? I could go on but, why make you drool..
There are available and for fair market price's. Some REAL DEAL off the hook strains that you've heard of....
I have to say. Some of the available strains from
www.drgreenthumb.com can be mind bending IF you dial them in and approach the plants potential!
TRY these,
Ghost cut OG - This is the first result from the breeding program to make the original OG kush! FANTASTIC strain! It
can hit 25% alone.....I had some test out right at 25!
East Coast Sour Diesel - Greenthumbs is in my book is the best version over any "well known" version.....
Remember that you need to dial in each strain to get the best results!
Happy growing
There's my 2 cents
