Standard distance for a 150hps is 45-60cm should be kept so throughout. PPF: 150w cutilite is 250 μmol/s. over 2ft x 2ft Should give you a rough PPFD of 672.74 µmol/m²/s. (100% no loss) Want ppfd of 100-150 for seedling stage. I'd at least increase height to 120 cm to account for light loss, a little in the low end but should keep you around 2-300ppfd should be good enough for at least half of veg too. Good luck and thank you 😊 🙏

Okay light distance is a tricky thing with HPS with them being so hot its quite hard to put them close to your plants without burning them I would maybe use a distance of around 50 cm depending on the temperature of your tent if its in the low 20x pout it to 30cm but if its higher id keep it high but the manufacture of the bulb you have should have a hanging distance recommendation either online or on the box good luck buddy
