Light Spectrum Chart

[DonJones]

Willl someone please post a link to that colored light spectum chart that shows where each differnt type of light falls and also the one showing what parts of the spectrum the plants needs/uses during the different stages?

I gave my last copy away and now can't remember where I down loaded it from.

Thank you.

Fruitybud,

Thanks. I didn't see the ones I was thinking about, but some of these are even more informative.

Here's a link to an external thread that contains a lot if useful information and spectral distribution charts. Check it out. It's a good one!!

It is important to understand that Hicks chart is in reference to ideal black body radiation. Bulbs that produce light by electrically heating a resistive element approximate black body radiation reasonably well. Flouresents do not.

This is important because a leaf's chlorlplasts cannot use all the frequencies in daylight. A leaf appears green in color because green light is of less use to the chloroplasts and is reflected back to the eye.

Can anyone help me I'm running 2 23 watt daylight florescent lights for my seedlings. I plan on getting more in about 2 weeks maybe a little.longer tho will this be ok for now and will the same lights work for flowering?
And btw they are purple kush bag seeds, mistake on the bag seeds I know but on of the twos srem is slightly a reddish purple color as well as green? Anyone know about that

ive never had that less of light b4 lol ..
usually had 2-3 32w+ t12's around.which that would be enough for sure for a bit....

i would say if you keep it close they will do for the 2wks..
and NO they will not do you for flower... seedlings n clones is what there good for..
HPS all the way my friend for flower..
what size of room you doing this in??
you getting a inline fan?

Perfect thread for this link, to a blog forum about light nanometer breakdown.

Thanks Light. You should be a valuable asset here.

Thank you,

I am using Mars ProII320 led, more red and IR for bloom, more blue for growth

 

[Devile]

This is full spectrum of Mars light. I did not study spectrum too much, but my girls grow very happy under this light, I harvested 1.2g/W.

thanx fruitybud , lot of help

 

[Aksarben]

This is the light spectrum of the 2 SANSI 40 W LED bulbs I presently use....

 

[Bruce111]

How do you think about this ratio? The light is Mars SP150 that i am using.

It's amazing light, I'm using SP-250 now.
