Advice what lamp for vegging.High guys,
My Jack Herer will move soon to a closet with a 60x60 cm surface.
For flowering I will use a 180 watt Hans Panel.
And I do have 2 led lights at home for vegging.
My first option is the Spectrabox.
And my second option is the Cree Cob led.
What is my best option?Setup. Lighting

Slow indoor seedling growth4 days since sprout, issues with light timer, seedlings ended up getting 48 hrs of light after they sprouted, and this AM I found that the timer did not turn the light back on so it got 11 hours of dark last night instead of 6. Could this be detrimental to seedling?Setup. Strain - Autoflowering

Doubling light/adding a panel in flowerAdding a second light panel-- any tips? Will it be too much?
I've been using a viparspectra p1000 in my 2x3ish closet and it's done me well up to this point. Today I've installed a second led panel (not as good as vipar). Wondered if it'll be too much?Setup. Lighting

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?6y ago

Just ordered a 150W Quantum Board, can I swap my Blurple UFO mid grow to the new board? Is it possible to increase flower size this late into a grow?My Blurple apparently uses 230W actual draw but is advertised as 600W. If that 230W value is correct, does that suggest my new, much more expensive QB is not as good? Will it make a difference to the plants health? What are the benefits from the QB? Thanks!6y ago
