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.

Seeds in 12/12
Does keeping seedlings just the first week under a 12/12 light cycle can hurt them? I have some seeds that are not sprouting after 7 days, maybe it's because the outside temperature is too low so I decided to keep them in my growbox with my other flowering plants until they start

switching lights from veg to flower.
Hi. Ive seen a lot of growers leave there lights on 24hrs or 18/6. Ive always switched mine to 12/12 when switching to Flowering. Has anybody noticed a difference when leaving lights on 24hr or 18/6 instead of 12/12. Thanks.

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#

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.

Grow Light distance
Does it matter what heights I have my grow light at as long as my pfd is where I want it? For example could I have it closer and less power or do I want it further with more power. Feel like it would be better for the light the less power being used.

Efficient lighting
Keeping both 200w VEG and 300w FLOWER lights 24h is too expensive for my alien wallet. So I left the veg light under 12h/12h and flower on. Please share with me some of your past experiences and how can I save money and grow killer yields. 👋👽

Can you use a 450 watt white led light to start seedlings? If so what distance should the light be and when should I make it closer? The reason I am asking this is because I don’t like transplanting autos as they are fragile to transplanting from what I’ve looked up

Diferencia en el color verde de las hojas
Estas plantas automáticas están recibiendo la misma alimentación, agua, etc y están en el mismo tipo de sustrato. Pero unas (las más oscuras) reciben luz artificial adicional (Neón CFL) para llegar a tener 17h de luz al día. ¿Es normal la diferencia? ¿Cuál se ve mejor?

Secondary Lighting
Would there be any sort of reason I shouldn't add a second less powerful light to the side of my tent? My thought is if my goal is getting more light to the lower growth wouldn't that be a good course of action?
