Maybe you over watered it. I bet thats it.
I just sprouted some seeds and they are growing there second set of leaves after 3 days.
Jdog7000 Reviewed by Jdog7000 on . Slow growth Hi All, I have a seedling that's been up about 1.5 weeks. It is less than 1/2" high, and has tiny leaves. Any idea what is causing this slow growth? I realize that maybe it's just working on building a root system, but it just seems like it should have grown some by now. I have a 400W MH lamp 32" above. Opinions appreciated! Rating: 5
