Resinator, my very first grow was Northern Lights auto. One grew and grew and didn't flower, it was over 3 ft by the time I pulled it up. My husband isn't one to let something like no buds turn him off so he let it dry and smoked it. There actually was something to it, we even ground the stems and made stem tea. The other plant, I call it my bonsai. It didn't get over a foot tall. It had measly buds, but I let it go until it was done and dried it out. It was pretty good. Better than a sharp stick in the eye.
Now I'm on my second grow. I have no clue what I'm growing, I got 3 Jackpot auto-fem seeds that didn't germinate and two auto-fem mystery seeds. That's what's growing. One is almost 3 feet tall, and covered in buds, she seems to have quit growing taller, the other looks like a totally different strain and is about half the size, but is going into the stretch and starting to flower. She's about 12 inches tall maybe a little taller, she grows some each day. I'm not a fanatic on measuring, I just know that I've had to raise my led light to accommodate the tall plant and the shorter plant loves the cfl and I'm blasting them from every direction with light.
Mine tend to want water every two days. I stick my fingers into the soil, all the way, I have short fingers so I go to the last knuckle and if I don't feel moisture I water. Guess maybe I should start picking up the pots to feel the weight.
And even though the seeds germinated at the same time, went into the soil the same day, the taller plant started growing immediately, while the shorter plant took 15 days to decide that it was going to have more than two sets of leaves. And then it took off.
I keep the attitude that they are weeds and they will grow how they grow. My next grow is going to be trained, these were free range plants. No topping or training but Green 75 has inspired me.
Good luck!
