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.

What’s up guys me again😂 I’ve got my hps up and running and I’ve got the temperature under control by having my fan blowing directly at the light and I’ve added a oscillating tower fan. How can I keep the temps up when lights go off? Many thanks!

Doubling light/adding a panel in flower
Adding a second light panel-- any tips? Will it be too much? I've been using a viparspectra p1000 in my 2x3ish closet and it's done me well up to this point. Today I've installed a second led panel (not as good as vipar). Wondered if it'll be too much?

NDL VS LED
So the switch to LED is happening, I hope the ladies are okay with it now... except for one bent leaf and the shock of suddenly getting rained on by poles, nothing has happened to them...🙈 this serves as a picture update since I can't change them in the individual weeks....

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?

Light power
Is a 100-watt lamp sufficient? I don't consume much, so I opted for a modest light, anticipating lower yields. Can the quality match that of weed grown under a stronger light(600watt), despite producing fewer grams overall?

Plantulas deben estar bajo luz?
I have a 240 watt 3500k quantum board LED. Does anyone know how long it's recommended to give them light with it? It has a dimmer, but I don't know if they need light in the seedling stage. This is my first time starting a grow with LED. Before, I would just put them in the sun for a few hours and that was it..
