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.

HPS 400w Vs MarsHydro TSW2000 cost
Does anyone know how much less a LED light consumes compared to an HPS? For example, I'm using a 400w HPS, and my electricity bill went up by €40. If I switch to a MarsHydro TSW2000, would it make a big difference? Thanks!

1 light or 2
I have recently purchased a Mars hydro SP 3000. Great light.. It replaces my Blurple Mars hydro exo 120. I wanted to ask what peoples opinions are about me using both lights for veging. My grow space is not that big. 1.8m x 0.8m and 2.35m high. Will it be too much light and heat?

Is this light good enough?
Will this be enough for 2 auto flower plants in a grow tent? Or will it work for one? The tent is 20x35x64. Or should I get another one or a different light altogether? Thanks!!

Which would you go with for a 4x4 that is used for veg and flower: Mars Hydro TSW3000 or AC Infinity s44? I've got myself narrowed down to these two options.

LEDs for 32x32 tent
New to indoor growing. Set up a 32x32 Vivosun tent. Currently have a giixer 1000w light, but wasn’t feeling the coverage was good enough for several plants. So I just ordered a second one. Do you think 2 giixer 1000w leds is ridiculous overkill? Any thoughts appreciated.

Lamp to Plant distance - Outdoor.
If growing outside, what is the best way to calculate lamp (star) to plant distance for the journal each week based on time of year and rotation of our lovely planet? I am being facetious, of course! It's just a fun question for you all. Hope everyone out there good!
