Is my lighting good enough?

    Hey y'all! First timer here.

    I bought this 4ft 30w LED shop-style grow light from Walmart and I was wondering if it would be powerful enough to fully grow 1 to 2 plants.

    I attached a screenshot of the specs.

    I also have a 75w LED light for a single plant that I got from here:
    a Light for Pot - Single Pot 75 Watt LED Grow Light

    Any input would be helpful!

    No it is not. It is really bright but not enough power. I tried that. The UMOL is only 44.19 and needs to be around 500-600.

    Something is wrong, either the given power or given current.
    Power = Voltage * Current =
    25-30 LED watts per sq ft is what you need.

    Damn, I was afraid of that. What about the 75w single plant light? I attached the PPFD chart for that one.

    I'm hoping I can skate by on it until I can get a MARS HYDRO light. But since it's for single plants I don't know if it will be good enough for my 2.
