I'm looking at Nirvana's Pure Power Plant, Snow White, and AK-48.

If anyone could let me know a few things like their experiences with some of the following:

Height, Yield, Flowering time, high type, germing success rate... you know.. the important stuff

THanks

You can get that info from any seedbank's website.
Use the search function and look at grow diary's and see.

Well I HAVE already seen what the seed banks say. My aim was to find out peoples ACTUAL experience with these strain went .
I wanted to see if anyone has grown them, and if they have, how close was it to what the site says. Main thing im looking for is are they worth buying. They look good on paper but I wanted some opinions.

Nitvana strains are cheap for a reason. That is, they simply knock off other breeders genetics, selling F2 and the rest under slightly changed names. Therefore you get cheap seeds, and take the risk that they will be OK. Sometimes they are. But sometimes, you just end up with stringy elongated genetic throwbacks with very little to offer the indoor grower.
Roll of the dice; do you feel lucky?

Of course, there is the moral dimension to consider if you believe in ethical shopping. Is it right for a seedbank to knock-off other breeders genetics like this? Big question.
