understanding light

[Luci_ferson]

a lot of people use the new oled light strips for fish tanks.

some of them are so effective they even work for corals.
corals usually only grow well under metal halides.

the new led lighting has many advantages but come shtf I expect no electricity.

Colour changes to light would really need to be done through filters.

unless your planning on getting a huge battery system and a solar panel.

electric light for plants in their flowering/fruiting stage is usually 400w per sq metre.
not easy to achieve with batterys leaving it not much of a possibility.

really only light extending is viable tool.

an extra 4 hours or so through a battery system with low wattage flurescents and colour filters would be enough for extending a plants vegetative state, and shouldn't be too hard to achieve.

allowing much earlier sowing of some crops .
