I have 2 mercury lamps from when I used to keeptropical marine fish
in an aquarium.
As these lamps are supposed to replicate sunlight,I was wondering if
they could be used to germinate seeds in the greenhouse when the
natural light levels are still low?
I hear cannabis plants are grown in secrecy using this method
indoors -- for obvious reasons!!
just a thought
No reason why not, though it's not usually cost effective unless
you're specialising in a high value crop whose light requirements you
understand very well. If you are sowing seeds that are going to
germinate before light levels are sufficient for good growth, chances
are your plants are going to be ready to go outside or will be needing
more space than you can give them inside while it's still too cold to
put them out. I've found that for my purposes at any rate, earlyish
veg production and the usual spring bedding suspects artificial light
isn't worth the bother.
