Dude... That's not weed. That's Hulk in green nugget mode. Flowered fast and well. I was super excited after a bong hit. Don't sleep.

Big plant, grows like crazy. Only problem is it still hasn’t started flowering after 110 days, no idea if it will or not. Other than that, all good.

All 3 seeds germinated in 12 hours! A day later I planted them in pots with coco and soil. Used sunlight during the day and 45W LEDs after 7pm when it started getting dark. They were going crazy during vegetation, gaining almost 40% of their green mass every day. After 18 days I put them outside under 10 hours of direct sunlight. Added banana peels, chicken manure and drainage. They adjusted within a week and then started shooting again. But then the temperature dropped to -2C outside, which I did not expect at all. I thought they were going to die but my Hazes all survived! In fact, they continued to thrive as if nothing had happened! They reached 2.5m tall with lots of side branches. I had to chop them earlier than expected but I am very pleased with what I got! 1.It grows fast 2. Even its leaves give a strong effect! 3. Resistant to low temperatures and diseases - no plague at all It is a little slow during flowering but I guess it is because of the bad weather - in a warmer climate it will do better. Happy growing and harvesting to you all!!!
