Lighting

[Hazzard]

Another one of these redundant lighting questions.
Just can't process all the info on the forum
I have a 75 gallon. 48x18x20 I do believe those are the dim . Currently and running a t5ho dual lamp. 108 total. 1 is 6700 and the other is 680 rosette.
Where does that put me. Low med high ?
And would adding another fixture be ok ?
I do not have the coin or time for c02 but want to be able to plant most plants
I do use excel. And root tabs
And lights are on 10 hrs

That puts you at low light. I have 105 watts of 6700K T5 and another 65 watts of 10,000k on my 75. it does a nice job of growing plants with out being high light. Add another 100 watts or so and I think you will be right where you want to be.

Great. Thnx for the tip
If I was to by the second fixture would you recommend the same set ? Or they also have a 10000 with a 480 actinic
I'm not overly fond of the hue the 6700 gives off. But if it works ...

Actinic bulbs will not provide usable light to your plants. You want to stick with 10000K. It is a nice white light, and good for plants.
