I went to Home Depot and got a full spectrum light bulb and a heat lamp fixture. I know it might not be as attractive but if you are looking for great grow light for your aquarium plants at a lower cost. I killed dwarf water lettuce myself, but now they are growing great. It's bright enough to light both 5.5 gallon tanks. See pics.
If I got a light like this- https://www.amazon.com/dp/B00X84LNS8
- would I be able to grow a low-light plant in my 3g tank? Or would it probably not be strong enough/the right spectrum/etc. Historically I have been a miserable failure at planted tanks (I have killed duckweed on two separate occasions) but I keep wanting to try, and the fact that this light is submersible is a neat gimmick that I like.
And if that is an okay enough light, or if there's a better light that's not too much more expensive, what sorts of plants could I have with it? Would I really need
anything like fertilizers or dirt substrate or is that only for if you're hoping for lots of growth?
