Good to leave any light you have, but I would recommend placing you HPS horizontally for max light to the canopy. Cheers

Sure leave them. Just don't break them they have mercury in them. Toxic stuff.

Hey, ich frage mich was die optimale Distanz der Lampen zueinander wäre, um eine Fläche von 120x100cm auszuleuchten? Die Intensität nimmt zu je näher etwas unter der Quelle ist Addiert sich die Intensität bzw der par Wert bei Überschneidung? Erfahrungen? Vielen Dank 👍 Cawa

Change lights off time?
I'm having trouble with temperature control. My nights get too cold. My current lights off time is 12am-6am. Is it possible to change it? I really want my lights off to be from 9am-3pm. I think that would help me a lot. How do I change it? Let my lights run for 27 hours?

23 hours light per day?
I’m running 4 autos in a 4x4 tent on 20 hours of light per day. I’m thinking about the possibility of changing the light hours to 23 hours a day and 1 dark hour. I’m currently on week 8/9, I’m expecting it to finish roughly 12/14 weeks from birth. Any thoughts on this growers?

Max temperature?
Max temperature accepted with lights on? I don't know when to use the lamp at full power, but when i tried i had 30°C at pot level with the lamp around 65/70 cm from the plants... That's too much i guess.

Is it too late for scrog and have I had the light too low during the veg stage?
So I noticed pistils appearing and now I'm worried that I've had my light too low during veg (~8k lux). Is it too late for scrog at this point or will they continue to grow? I've now bumped the light up to 22K lux should I lower the light to increase the intensity even more? TIA
