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.

Light height
Hello all I have a mars hydro tsw 2000. I was noticing the recommended height is 24 inches for seedlings. Is this at 100% intensity? That's well over 1000 ppfd by my meter. I thought seedlings could only handle 200-400?

Hight Problems
I’ve got 3 plants in my tent, but they’re all different heights. To compensate, I’ve hung my light at an angle, so one end is closer to the smaller plants. My question is: Does this help, or am I better off keeping the light level? Any tips for dealing with uneven plant heights?

Hello grow masters! I would like to ask you if mh 250w and hps 250w are good for veg (the fist one) and flower (the second one) in my 80x80x170. I would appreciate some opinions and advices about my 3 ladies too. Remind that this if my first indoor grow so don't be bad with me!

6 weeks of veg? I got only 3
Why do i see some auto or non auto diaries with 6 week of veg? When i grew non auto i just had them 3 weeks then switch the light time and changed 400w to a 600w. I learned that because they used to get hella big. And in Auto seeds i switch the spectrum after 3 weeks

Should I lower my light during flowering?
I'm at 24 inches away now, should I lower the light now that she's in full bloom? I went with the recommendation of Mars Hydro and burnt up 3 seedlings as a result. Sadly I only have one bean left of my Fastbuds over this crucial mistake. Running a Mars Hydro SP 250 keep at 36in.

Review this model or help me create a DIY COB plus IR plus UVB grow light.
I've very limited variety of lights in this country so this is all I can find. Also there are no suppliers who provide spectrum charts or any temperature values for those lights. My goal is to make it with the best possible light spectrum. Having IR's also will help on cold days.

When to turn the light on after sprouting?
We have a sprout! Tropicana Banana sprouted between 10pm last night and noon today. Can I turn the light on now, and start the 18-6 schedule tonight or will it fuck it up if I turn the light back off at midnight tonight to begin the 18-6 schedule?

Swapping lights during flowering
Do you guys think that swapping lights at the late flowering stage is going to harm my girls in any way? Been fortunate enough to be able to order myself a Viparspectra xs4000 to replace the v600. And as I understand it should be quite an upgrade. Thanks for any advice!
