Hey Omni, I got mine from a local gardening/hydroponics shop. Might be worth checking locally first. Also, I'd think that with Amazon's great return policy if you got expired/outdated stuff you could send it back pretty easy.
Yes. The leaves are so big and nice looking and they aren't blocking anything yet. I'm going to wait until a few more branches pop out and then probably snip them later. They do seem to be powering the plant really well. Plus I'm not quite a pro like you. Still learning and experimenting. Small slow steps at a time.
