I grew some bud when I lived out on maui... but it was outdoors and grew itself... all I did was trim from time to time to get the bottom leaves off that were dieing... but yea... so here is what I have...I ordered and received 10 blue mystic seeds from Nirvana( great job! stealthy shipping and fast... 10 days from holland to AZ) anyways...
