Is 300w LED light enough for a 120cm x 60cm tent setup?

So i recently upgraded from a 40cm x 40cm using a mars hydro ts600 (100w light) to a 120cm x 60cm tent, and to go with that i bought a mars hydro TSL 2000 (300w light) will that be enough or should i get some vertical bars for the corners to supplement the 300w? For context and if it makes any difference, i will be using autos, namely, blue cheese auto(barney farm) and sour diesel auto(ice seed bank) in canna terra professional medium and biobizz nutes for veg and flower.

It may even be a bot overkill: autos get much more total light per day since they arent constrained to 12 hours in flower; if you ran 300w for 18 hours its the same total light as 450w during 12h.
Keep it dimmed and look for signs for possible overlighting.

8 square feet ( 4x2) divided by 300 = 37.5 watts per inch.

Standards are 45 per square feet for top light saturation . This does not mean you can not saturate with 37.5 watts per. You just will not be able to cram the tent wall to wall for yield. If you just use one less foot and keep the light concentrated on the other 7 feet you raise your light concentration to 42 watts per foot.
Training will be key.

45w per is pretty excessive.
Unless you have small plants, with some serious growing space vertically.
