leftreartire Reviewed by leftreartire on . Starting Hydro Grow, is my seedling healthy? Hi there, just started my first hydro grow, and am right now sprouting hawaiian haze x plum from seed. It's been about 5 days since it first popped out of my rockwool, and has been growing relatively consistently day to day under a 400w MH @ ~3.5 feet above. I am slightly concerned however as it seems like the stem is getting a bit wobbly, and the cotyledon seems to be drooping. (see pic). Am I all good, or is my seedling suffering / what can I do to remedy it? Thanks guys, great Rating: 5
