I’m a beginner grower, my first try was with some mystery seeds I collected. Out of 3 plants, I yielded a little over 2.5 ounces. So I ordered better seeds and have sprouted 1 of them in soil. It is now 3 1/2 weeks old and under a 250 MH lamp. It is about 3 inches tall. It just seems it should be bigger at this point. Any suggestions?
