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.

Should I switch to flowering now?
The height of my growbox is 120cm (4 feet) and I'm afraid that sativa can grow taller than that.

LEDs lumens
is there a method (which does not involve the purchase of a rather expensive device) to measure the lumens present in the growbox? I would like to make sure that the LEDs that I bought have the same performance declared on the package 😕

NEED SOME ADVICE! Change to LED from HPS? which ones are good for tent size? Which ones are good for good yields?
I've got a 4x4 tent with 8 seedlings in cups but will be in 11L pots. Currently I had a 600w HPS light but my ballast busted today. I have a back up CFL 150W not to mess up the light schedule. Thinking about changing to LED lights, I know it'll be cheaper but I want same yield...

Confused with light schedules for outdoor growing
Hi fellow growers, I'm really confused with light schedules for outdoor growing. Everywhere I see 18/6 for veg and 12/12 for flowering. However at my place I get ~13hours of daylight (not always sunlight) Would my plants get into flowering if daylight is reduced to ~11 hours?

LED light - Veg / Bloom
Hey guys and girls, I have 2 autos that are a week old and looking strong. I have a Phlizon 600W Led light which comes well recommended. It has 2 switches. VEG & BLOOM. You can have 1 or both on. Should I have both switches on (full power) at this early stage or just VEG?

LED glass/plastic cover.
Glass/plastic cover on cheap led lights.. do you remove them or not? From keeping reptiles I know that any glass/plastic will reduce UV. Just wondering if anybody's noticed any difference after removing the glass.

Posible quemadura?
Cada vez que entro en floración me pasa esto y no encuentro solución. Uso una tienda de 1,20 x 1,20 y tengo un led de 730w empiezo a pensar que la luz es demasiado potente y las plantas sufren de calor. Hubo dos dias en los que llegó a 32 grados actualmente estoy en 29/30

When to flip LED's 'bloom' switch on?
When's the best time to flip the 'bloom' switch on my LED with an auto? Should it be at the first sign of pistils or is there a better time to do so? I have already flipped the switch for this plant and kept photo-period the same, looking for info for next grow. Thanks!

Too early to turn up the dimmible LED light on my seedling?
Unsure if it's too early to turn my light up just yet or wait till more leaves are growing. Currently at 25% (10,000 lux aprox.) using the dimmer for a 120w LED at 20 inches from seedling. Thanks in advance.
