With a PPFD at 300 you well only get a DLI (Daily Light Integral) of 25,9 if you run your lamp 24/7. From what i know seedlings/you plants need a DLI of about 20, so you should be good but i would aim for a DLI of at least 30 even for small plants.

Try the same PAR but with lights closer. The seedlings turn out stretchy when the lights are far away

Par is lights output, wavelengths and such area covered and so on What you're needing to understand is ppf/ppfd. 4-450ppfd for a young veggin plant. Have a read on growweedeasy to understand. Ill try find a link and dm

Is my LED too close or too far from my plant?So this is my first grow and it feels like she’s growing a bit slow. Currently at day 10. Distance was 62 cm. The LED is 100W. Now the distance is 57 cm. I’m wondering if I’m just impatient. Is this distance appropriate? How is the growth looking?

Irregular light schedule.I am thinking about giving her 24h lights a few days a week and then go back to 18h. Just to give her a boost. Will this irregular light schedule harm her? My first thought is that it doesn’t matter much since she is an auto, however I know that plants love balanced environments.

Grow light question I bought a cheap light by KingLED. It’s only 100 Watts and I’m unsure if it’s enough for one plant. The light has 2 switches, one for veg and one for flower. Should I always have both on since it will be an autoflower?

When did the flowering start?The LED panel, after switching (Ts600 Mars Hydro), stayed slightly on even during the dark hours. I managed to fix the issue, but I'm not sure how to count the flowering period. The plant had shown some differentiation, a few pistils, and a bit of stretching. What do you think?
