I also have a 600-watt version of this. I could use them both if need be but it's only a 2x4 tent that I'm planning on using for veg.

Don't flush, keep low ppm, 200-400ppm, to the end. Flushing is a band aide for people who nuke their pants with nutes. These plants aren't dead when we cut them, they still have active biological process going right up to, and actually after, they get cut and still need a full spectrum of nutrients, at reduced levels.
Give them what they want, no more, no less and they will stay healthy to the end.

Get an inexpensive multimeter and check your wattage at the wall. A lot of UFO mfrs will base wattage on the diode's max limits rather than what they drive them at. A quick check on Amazon for sub $200 1200w equivalent LEDs shows 250-300w ratings at the wall.

Plants will grow under any reasonable light source, not necessary robustly, but they'll grow. From the specs on that brand, the case is the most valuable part of the build
. If you're available for the get together I've suggested, bring the 600w along and I'll see if maybe it could be upgraded with 5000K white COBs and give you a real veg light. I know you can upgrade a MARS light that way, be interesting to see if we could do the same with yours.

There is an interesting discussion going in the quantum board thread about watts/sq ft. For HPS, the going advice is you need 50+ watts/sq foot. So about 400 watts in a 8-9 sq foot tent (2x4, 3x3).
The Quantum guys are saying that under cobs/qb, that number is closer to 25-30 watts/sq foot. So even at 30, that's only about 270 watts for the tent in flower. Figure half of that to get you through veg.
That's one QB or 2-3 cobs depending on driver. And then you only need that much towards the last week of veg. And, they have the flowers to prove it.

I'm about to move the girls to a 2x4x5 Vivosun tent with 2 5000K Quantum boards in series on a MW HLC240-1050B which should give me a little over 100w per board. Should be an upgrade for veging ovr the temporary 4000K x 4 3590s @ 1400ma they're under now. Just waiting for my Wago connectors to arrive to finish wiring it up. I'll post the configuration once it's up ... 42" x 18" angle iron frame.

My bad, the 240-1050 goes up to 238 fv, so it will work. I was thinking of the 1400 which only goes to 129 fv. That would get me to about 125 watts a board, but I have to do them in parallel.Yup ... sure about it
Of course I was sure that Trump could never win too
That is, if they are ever back in stock.

I think Arrow has the best driver prices at the moment. You might want to buy that while they're in stock. Free shipping over $50.

Starting week 5 on the Blue Widows. All 5 have been topped and started on lite nutes. Lowered the lights from 30" to 24" ... everyone seems happy.
