The strain Juicy Fruit aka Juicy Fruit OG aka Fruity Juice is from Sensi Seeds. It is an exceptionally fruity strain.
Fruity Pebbles ((Grandaddy Purple x Green Ribbon) x Tahoe Alien) is altogether a totally different strain than Juicy Fruit (Afghani x Thai) is.
When Fruity Pebbles was made back in 2012, it was a very limited one time seed run and seeds were going for up to $1500 per pack of seeds.
