Okay, thank you, that makes more sense.mikethecactusguy wrote: ↑Sun May 16, 2021 3:48 pm 10,000 lumens at plant surface is the minimum you want to grow plants indoors. Forget about watts and amps and everything else. 12,000 lumens is shaded sun intensity. What does this mean. You have to physically measure the light that reaches your plants. If a Lamp outputs 5000 lumens that is its rating at the lamp surface. It will drop substantially 12 inches away at the plant surface. Download a light meter app for your phone and use it. Buy enough lights to get 10,000 lumens at plant surface. That is the easiest what to explain lighting.
Unfortunately, I actually don't have a mobile phone, but I could buy a lux meter; I've been indecisive about which brand to buy (my budget is under $50), and the negative reviews seem to be coming from experienced growers/photographers; as opposed to a majority of positive reviews mainly from less-experienced individuals, it seems. I've considered getting one for about a month, but I haven't made any decisions yet.
Hopefully my current light will, at best, help transition my plants to full sun outdoors; I'm really not sure, as I have no way of proving/analyzing the light's spectrum, PAR/PPFD values, etc. I just have to rely on the manufacturer's claims.
