Hello Amsterdam. I am a brand new grower. Got my bathtub filled with 10 plants and 4 foot grow light. Since 8 weeks ago I harvested 4 plants that grew beautifully. Got one ounce yield per plant. ANYONE can autogrow. Stop paying for weed. I've grown AK-47, JAH and Northern Lights. They all grew beautifully. My $100 Amazon grow light is the reason these suckers grow so well! My mother wants me to plant tulips next....she thinks I'M TALKIN to Holland spread the word. These guys ship fast as hell and there seeds work! I have been passing your website to everyone I know. Be confident. You can grow it! Tim from New Jersey USA

Just got my auto Indica pack today. Lights xtrm, habiba and big bud auto with 5 free widow fem. Can’t believe how quick it got here! I ordered mid December, and here we are, inclusive of holiday season and the fact I’m in Australia. Very, very pleased and can’t wait for my beautiful soil to arrive so I can start with the mighty northern lights strain. Super keen from previous lights experience through indulgence, and now to master it myself and reap the rewards with what looks like a great strain from you guys. Can’t wait.
