It’s not 1000 watts
25 umols at 18” is terrible.. But just starting the first week is ok I suppose.
I’m shooting for 100+ the first week of life

Hi
Personally I would hang it quite hight when seedlings like 5-600 mm away
And slowly lower it as it starts to gain height as you dont want it stretching too much,
If it has a dimmer the obviously wack it down abit, if not start high and lower bit by bit 👍
Good luck bro 🌱
Other wise

Bei dieser Lampe ist die Beschreibung der Wattleistung etwas trügerisch.
Ich gehe stark davon aus, dass sie keine 1000 Watt tatsächlichen output hat.
Das halte ich für nahezu ausgeschlossen.
Schau mal auf die Rückseite der Lampe ,auf dem Typenschild nach der eingehenden Leistung.
Danach kann man beurteilen, wie weit der Abstand zu den Pflanzen gewählt werden muss.
Pauschal würde ich es bei dieser Lampe mit 30 cm Abstand versuchen. Aber ohne tatsächliche Leistung ist das schwer einzuschätzen, zumal man sich da generell vorsichtig herantasten muss um den optimalen Abstand zu finden

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?
