Hi Kanno!
Yes P600 should work fine in 2x3 tent for the veg phases.
It should cover the 2x2 footprint pretty evenly - I guess the lamp PAR was tested in 2x2 area (60x60cm).
Just make sure the P600 has Vipar’s new tech incase youre ordering it from somewhere else than Viparspectra own online store; it should have Samsung LM281B+ diodes and upgraded driver (I guess it wasn’t MW’s).
For the flowering phase it might not be enough in 60x90 tent.
Anyway it is one of the cheapest and most efficient 100w QB on EU market.
If you’re looking for a decent LED that you can use from seed to harvest in that 2x3 (60x90cm) tent, then I’d maybe choose VB1500:
ViparSpectra® VB1500 150W Infrared Full Spectrum LED Grow Light
It is a 150W Quantum board with the same latest Samsung chips and it has the better and more efficient Mean Well driver. And because of the board size/width it should cover the 60x90 area pretty well. Also it’s only about 30-40$ more than the P600 which is 50W less consumption.
TLDR would be; for 60x90cm tent the 100W would be the ”minimum” to cover the whole area and 250W prob max.
If you’re looking for the cheapest QB’s then google ”Kingbrite” or if you looking for more efficient LED’s then try look for Cree Cob Leds - just make sure they cover your wanted area.
Just tag me if you need a futher help to choose good led light.
