It could, very true. I guess I'll have to go buy some Top 44 from them to test the theory 'cause I've heard on other forums that Gypsy's genetics have taken a turn for the worse, cause in the past I've ordered from them 3 or 4 times and their genetics have always been pretty uniform, which given their vocal detractors I didn't think would happen. It was only with my order from Hanf I had a problem. I just (based on my experience) am not a fan of Hanf.
Nirvana has some good strains for a real good price, ideal for those growers that have outgrown bagseed but don't want to spend hundreds of dollars on "name" genetics.
I had a Nirvana White Widow that was in my garden for years, I just recently replaced the mother plant with a G13 White Widow. The G13 has been the first white widow from another breeder I've found (haven't tried them all by any means though) that beat it.
