Some Calculations...
1... 4' x 4' = 16 sq ft or ~ 1.6 sq m (m2)
2... 5' x 5' = 25 sq ft or ~ 2.5 sq m (m2)
3... 6' x 6' = 36 sq ft or ~ 3.6 sq m (m2)
The typical recommendation (based on HID Fixture Watts):
1... @ 30 - 40 Watts (per sq ft) * 16 sq ft = 480 -
640 Watts
640 Watts * 1.5 PPE(PPF/W)
= 960 PPF
2... @ 30 - 40 Watts (per sq ft) * 25 sq ft = 750 -
1000 Watts
1000 Watts * 1.5 PPE(PPF/W)
= 1500 PPF
3... @ 30 - 40 Watts (per sq ft) * 36 sq ft = 1080 -
1440 Watts
1440 Watts * 1.5 PPE(PPF/W)
= 2160 PPF
Recommendation based on PPFD and Efficient LED (Strips and Boards):
1... @ 80 PPF (per 0.1 sq m CO2 Enhanced Flower) * 16
= 1280 PPF
1280 PPF / 2.5 PPE(PPF/W)
= 512 Watts
1280 PPF / 72 PPF each (BXEB-L1120Z-35E4000-C-C3, Gen3 1120mm) =
18 strips (486 Watts)
2... @ 80 PPF (per 0.1 sq m CO2 Enhanced Flower) * 25
= 2000 PPF
2000 PPF / 2.5 PPE(PPF/W)
= 800 Watts
2000 PPF / 72 PPF each (BXEB-L1120Z-35E4000-C-C3, Gen3 1120mm)
= 28 strips (756 Watts)
3... @ 80 PPF (per 0.1 sq m CO2 Enhanced Flower) * 36
= 2880 PPF
2880 PPF / 2.5 PPE(PPF/W)
= 1152 Watts
2880 PPF / 72 PPF each (BXEB-L1120Z-35E4000-C-C3, Gen3 1120mm) =
40 strips (1080 Watts)
[Note; 2.5 PPE = 167 Lm/W * 0.015 (Generic 4000K, 80 CRI PPF/Lm factor)]
Selected Drivers, Dimmable:
1... HLG-600H-42AB = 1 @ 600 = 600 Watts * 2.5 PPE (18 - BXEB @ 33.3 watts each strip) = 1500 PPF
HLG-240H-42AB = 2 @ 240 = 480 Watts * 2.7 PPE (BXEB @ 26.6 watts each strip) = 1296 PPF
XLG-240-H-AB = 2 @ 240 = 480 Watts * 2.7 PPE (BXEB @ 26.6 watts each strip) = 1296 PPF
2... HLG-480H-42AB = 2 @ 480 = 960 Watts * 2.5 PPE (28 - BXEB @ 35.5 watts each strip) = 2400 PPF
HLG-320H-42AB = 2 @ 320 = 640 Watts * 2.7 PPE (BXEB @ 23.0 watts each strip) = 1728 PPF
XLG-240-H-AB = 4 @ 240 = 960 Watts * 2.5 PPE (BXEB @ 35.5 watts each strip) = 2400 PPF
3... HLG-600H-42AB = 2 @ 600 = 1200 Watts * 2.5 PPE (40 - BXEB @ 30.0 watts each strip) = 3000 PPF
HLG-480H-42AB = 2 @ 480 = 960 Watts * 2.7 PPE (BXEB @ 24.0 watts each strip) = 2592 PPF
HLG-240H-42AB = 4 @ 240 = 960 Watts * 2.7 PPE (BXEB @ 24.0 watts each strip) = 2592 PPF
XLG-240-H-AB = 4 @ 240 = 960 Watts * 2.7 PPE (BXEB @ 24.0 watts each strip) = 2592 PPF

BTW, I'm not a "Grower" but IMO the BXEB-2700G CRI 90 LED Strips only require a "Blue" Wavelength Supplement (~ 420 nm "Violet" wideband) to become a true "Full Spectrum" (400 - 750nm) light source.
