Will 2700k work for plants?

Coral Keeper · 09-15-2007, 01:41 AM

Has anyone ever tried using 2700k, CPs, spiral bulbs on a planted tank before and have had the plants grow and live?? I am thinking of doing a experiment, get a small tank and put 60 watts of CPs thats 2700k and leave it in a dark area where theres no sun and put a plant in there and see if it dies or grows and lives. Dos anyone think it will work?

If you got time, give it a shot. I've read that plants do well with at least 6500k. The only thing is, depending on the size of the tank, 60 watts maybe too much.

Oh, the plants can survive with 2700 K lights as well. It's just very red/ yellow... so the colour of the water/ tank is not that great. Would be good to know how much there is output in the blue with those CPs. The plants need those frequencies, too.

Quite often the lowest Kelvins suggested are in the 4000 K range, I think (for example C. Kasselmann suggests this), though on this forum the suggested range is roughly (5000-) 6500-10.000 K.

Will be interesting to read how your experiment goes.

What's your tank size & what plants were you thinking of?
