Plants fail to thrive under Tesler grow light
I have a round Tesler Style # W2233 90 Watt LED grow light on my balcony, about two feet above my plants. It goes on at night and stays on for about 6 hours; but my plants seem not to benefit from it; they are not growing, or thriving.
I suspect, from a previous post; in the wrong forum, that I should be leaving it on for over 12 hours; so I'll do that. But I was also told that, for the most part, it's pretty useless.
