I would think it is specific to each type seed.
what is the original location ?
an African tree and a South American tree could have very different requirements.

Just for germination, i would think there are some basics
keep it warm and moist, but dont let fungus take over.
(i use a very dilute hydrogen peroxide /water solution)

as far as light.
the reading i have done on colors said there is really no difference.
any reason not to use white ?
except, you may want to stay away from green-only.
also, the color yellow attracts fungus gnats, if that happens to be a concern.

Thanks greenman
I was talking only about sub tropical plants
what strength peroxide do you use and how much do you dilute it
do any one use flower of sulphur on plants

Even within subtropic there will be variations for every species to get highest % germination. What specific seeds do you have in mind?

Greenman62, Iv always thought peroxide was mostly to prevent mold, does it also help with germination other than that? I don't have much mold problem if I use cocopeat so I have never tried it. im also scared of frying seeds like it does on my skin!
Does peroxide help in chemical scarification like hydrochloric acid?

Stuart I was thinking one temp that is constant would be better for any sub tropical seed than fluctuating temp especially now in winter time......Google all the uses for flower of sulphur...amazing stuff we bought them by the fifty kg bags when I was farming

I use to germinate anything between 20º C and 32º C (ideally 30ºC) in ziploc bags or sow in a good soil and keep humid; when they put the first leaves, humidity is very important for most of them -not too much for moringa, grewia or cashew-, I use to germinate jaboticabas, guavas, annonas and so on.

I think that is a good temp range anything much higher than 30C and you may make mush! Also it can help to use bottom heat, with mangosteen for me they appreciated warm soil from bottom heat much more than without. The best tool I ever got was small humidity and temperature high low checker I would be lost without it!

Nickytwo iv heard of sulfer to help acidity in soil and I think as pest control iv always been abit scared of it as when I think of it I think of fire brimstone and noxious fumes lol. Time to educate myself I guess:)

i just use the store bought stuff which is %3
then dilute that to about 1/20 or 1/10
just a few drops in a glass of water helps.

Some say there are other chems used in it as buffers, but i have used it %50 out of the bottle on seedlings with no ill effects
(as a test)
and have used it on a drowned papaya plant (root-rot) straight from the bottle.

it helps root rot a bit, but only for a short time. if you are able to dry out the roots after, its a good idea.
if not, you just prolong the inevitable.

i doubt it does much to help germinate, though, there could be some very slight breakdown of the seed-coat.
i just use it to keep the fungi/mold away with seeds and seedlings
in a very dilute solution.
