I always figure one oz/sqft is a success. 2oz/sqft is a home run. Same as led but uses more power.

Slightly under powered. 400w would work better in that space.

That’s what I was guessing, don’t forget to mention quality leds should produce that lol!! &
I agree which is why I’m just gonna run 1 plant in 3gal & see what she will do. I was hoping to score a 2x2x72 but flu has everyone becoming a home grower so tents are scarce rn. Local hydro shop has. 315 watt sunsystem I may take one of my 150s back n pay the difference that would put me at 465 with HVAC I should be fine. Sorry chatty Kathy sativa make me talkative

Pretty sure they still use different ballasts. You would need a conversion bulb, unless its new tech idk about.

Yield depends on strain and environment. For good yields you need the right genetics and a strong light, whether its hps or led doesn't matter as long as temp/rh is good.

The bulb type matches & the watts just don’t wanna fry the fixture. But then I got too thinking how does the fixture know if the light is hps or mh it’s simply looking for the 150Watt connection right?

I couldn’t locate a 150W conversion bulb sadly o could find one in 250 & above. The new tech apparently combined mh &hps together

what’s up my farmer folkss! Here she is my first hps grow 150watt.. 3 gal flip to 5 gallon
She’s chunky I’m shooting for gram per watt fingers crossed.. question of the night is she’s mostly milky on the trichomes should I be closing in harvest or should I try n extend until I see a few Amber trichs
She’s in flush mode no nutes for 2 weeks sitting about 1000ppm she was a heavy feeder had her up to 2200 plus with no nute burn probably could haven’t went more
