would this light be ok for maybe 2 plants

How you get there is up to you.

SCROG is good. So is topping your plants and training them. So is growing lots of small plants. But leaving plants assume their natural "Christmas tree" shape in an indoor grow with a fixed light source probably is NOT the best way to optimize light usage and get the best yields.

ok thank you for your time. so if you was in my spot. would you buy that light to grow 2 plants? or if I did train them, how many plants do you think I could grow with that light at once?

Price is $45 per 55w, but with a much better reflector than the one you list. If you buy more, the price decreases ($75 for 2, $135 for 4).

I can tell you that 4 55w bulbs will generate a bit of heat. With nothing more than an exhaust fan in the top of the box and a fan blowing across the canopy and past the bulbs, I was having issues keeping it under 86F. I made a custom fixture for mine with a fan pull cool air in across the bulbs and out an exhaust, and now I average 77-81F.

Thank you. The light I posted is just 2 55watt bulbs with that light system. Total 110 watts.
