Growing Black Domina as my first.

So for my first real Grow (field grows back in High school not counting...) I went with Sensi Seeds Black Domina. I am using Fox Farms Happy frog and some starter pots at the moment with 5-7 Gallons to come later. Sadly just tap water this time around. Sadly i have no good way on hand to help the humidity this go round but hopefully i can just water more often or run a string setup to help it... Everything inside a Mammoth 3x3 tent under an Oeno 1000w led light on full spectrum. I lost another seed of a different strain (most likely just human error) so i will attempt to use the cut off from each current plant when i manifold them in a few weeks to just fill in canopy.
