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.

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!!

Light intensity for 2.5 week auto flower
Can anyone recommend how high and what percentage to run my light. The leaves have not been strongly perked up in a few days and I wonder if it's that the intensity of light is too high. I've been at 80% at around 14 inches. vipraspectra p600. Critical purple auto.

Are these stretching? What should I do for the 2x top that barely sprouted?
Viparspectra xs2000. Just moved it to a 25" distance and 50% light intensity hoping it'll help, but unsure if it'll burn them? What should I do? Top 2x seeds JUST sprouted and are just barely above the soil. How to accommodate all plants regarding light intensity and distance?

Should one decrease light intensity during early flower?
Should one decrease light intensity during early flower, and then gradually increase again? I see DLI/PPFD recommendations for flowering in general, but not for the different stages of flowering.

How much light does a seedling need?
Is there a limit to what it can use? Could an LED grow bulb a couple inches away provide enough light? Up to what age? Thank you so so much. My first grow and I really appreciate it! Specifically this one https://www.gelighting.com/led-bulbs/e2624/ge-grow-balanced-spectrum-br30#

What % to keep lights at during late veg
My question was around what power % I should have my lights at? My light is 300watts so I am assuming 50% = 150watts? Is this enough to continue vegging my plant? I have noticed the growth isn't as vigorous.

Are 2x 150 watt lamps as good as one 300 watt lamp? I am thinking about upgrading to 300 watts, I already have a Mars Hydro TS1000 with 150 watts. (in 80x80cm / 2.625x2.625ft.) Thanks for your recommendations growmies😎

24 hour light cycle?
How advisable is it to run 24 hour light cycle? I’m interested because I live in the north and we’re getting to winter. The light divers provide some heat. They’re autoflower OG Kush.

Light cycle
As this strain is an auto, going on 12hr of light during flowering won't do her any harm right ?

Viparspectra LED tips
I’m looking into buying a viparspectra in the future. Which one is best for one plant? I’ve been looking at the 600W one, but I don’t know if that’s the best option for growing a good yield plant in a 80x80x160cm tent.

Can I use 18 on 6 off during flower when growing autoflowers and using ViparSpectra KS5000 LED at 100% power?
I have a tent with a ViparSpectra KS5000 LED lights. If I am growing autoflowers and they are in the flower stage do I have to change the light/dark schedule from 18 on/6 off to 12 on/12 off or will it be ok to keep the lights on a 18/6 schedule since they are autoflowers?
