No disrespect image reaper but i disagree with you to an extent...i've used Nirvana in the past and have been amazed at some of the pheno's i've got...now in some respect u get what u pay for but on a tight budget you can get some damn good strains...i've grown their Bubble gum and had a terrific sativa-pheno that was pink and completely covered in crystals (knocked me out at 9wks flowering) also i've grown their AK-48 and not one pheno was bad...3 sativa pheno's and 2 indica...the 2 indica's finished in less than 8 wks and were very couch-lock...got that lucky cherry-sativa pheno that had an enormous yield and a soaring high (some one hit quitter bud)...some ppl knock their strains and i understand why (f-2's, not much stability unless u stick to the basics, and sometimes a mutant here or there) but as a beginner they're some great genes to practice with...i've grown Mandala also and would say they do beat nirvana when it comes to uniformity and ease of growth but then again nirvana has some narcotic strains that Mandala has not yet produced...and i mean no disrespect to Mandala because they're plants are an absolute pleasure to grow...but if u want some NL, WW, WR, Afghan, ak-48 and u're low on cash nirvana has some good strains...just my 2 cents
