I have another question if you can help.
What height should I have the light above the plants?
Manufacturer say 24 inches whereas people have said as close as possible without burning the leaves.
My 1st time indoor growing.
I have a Phlizon CREE COB 1000watt light.
There are 2 switches...
VEG & BLOOM(on/off)
and
STRONGER(on/off)
currently have seedlings and only have the veg&bloom switch on.
Is this the only switch I should have on now?
If so, when do I use 'stronger' switch?
Do i use...
