Hi Katsu,
Replacing a 1000w hps with leds will require a bit more than just changing lights, it will need adaptations in growing style a bit. Mostly because of two factors, first is light spread and intensity, the second is less radiant heat coming from the light.
I think cobs on pc coolers are the least expensive option and have the benefit of good light intensity when driven at 100w/cob. The quantum boards will have a better spread but lower intensity so the taller plants won't get enough light in lower parts.
Usually this only means you need a bit more lst or scrogging for good canopy management.
My choice are cobs, bridgelux vero SE driven at almost 100w and the plants like it a lot.
Just another thought, i have a feeling that plants which were bred indoors under hps exclusively might show some lockout deficencies during veg and bloom phases, so feeding will also need some adjustments.

Take care and have a great weekend.

Cheers

Hey Katsu,

Definitely give the second generation Fluence Spydr2p a look. Little cheaper than the outgoing model, big improvement over the original. Check out @poetryofplants he broke 3 in a 4x4 with one of these if I remember correctly. (We're all stoners here. Lol) ✌️
