Plants are dieing, please help!

I'm very curious about your Saltwater aqua lights. Are these the 9325K light spectrum? I'm having a hard time finding exactly the ones you have. From what I read on that spectrum and aquarium use was that it had deeper light penetration I'm assuming in water. I once thought about an aquarium grow so this is all very interesting to me. Is the aquarium glass or plastic? And what's the ambient temp of the room? Also what kind of intake do you have? Cool setup on the hood btw.

I believe 9325K is what they are. They produce more red, blue and green light. I'm aware that the plants can't see the green though. The aquarium is a normal 55g all-glass aquarium. The temp of the room where the aquarium is around 70-75 degrees. The intake/exhaust is incorporated into the hood, but is seperate from the light system. That way I can constantly cool the lights without the lights producing too much heat and affecting temp or humidity. While the other fans control temp/humidity within the tank. I will post a pic of it tonight.

Thanks for your interest!!

I transplanted them into thier own containers, with 2 air stones in each. The root system is INSANELY HUGE. I will post pics later.

Here's my setup. Notice the hermit crabs at the bottom. They enjoy the weather! There's 20 of them in there.

:jointsmile:MALE OR FEMALE? Can I even tell this early? They are almost 3 weeks old.:jointsmile:

I've attached a photo showing what spectrums of light are best absorbed by photosynthesis using chlorophyll A and chlorophyll B. Using Kelvin we can use this formula to determine light spectrum in nm (nanometers.)

3,000,0000/K temp = nm

So at 9325K the math come to 321nm.

So, from the attached graph you can see that the plant is absorbing the most light at the two peaks for blue and red. I agree that blue and red light emitted from your bulbs might sound ideal but I'm not sure as they fall anywhere near the absorption levels as a normal 6500K Daylight bulb would do. I've haven't seen too much evidence so I'll leave it up to you or anyone else that knows a bit more to lend me advice.

The bulbs many people use (6500K) fall in the 462nm range. You can see they are a little closer to those peaks between chloroA and chloroB in the blue spectrum.

I've attached a pic from the box the bulb came in. Seems to show lots of orange in the 610nm range and blue range in the 430nm range. Ihaven't done too much research on lights so I'm not quite sure. The plants are thriving in it though, at least the new growth is, lol...

Looking good. I did some more research on your lights and mine as well. There is so much contradictory evidence around the net about photosynthesis response. Comparing the 6500K and 9325K, however, seems like your emit a bit more wider blue spectrum than an equivalent brand daylight bulb. So more power to you. :jointsmile:

It's opening a whole new can of worms for to educate myself on light spectrum emission, but that's another story. So here I am eager to see some results! Looking forward to following your grow!

Looking forward to having someone as excited as I am! I'll keep updating. :thumbsup:

Do plants double in size when put into flowering? If so, I think I'll have to flower soon because I'm running out of room! Does anyone know if it is too early to flower? They are about 6 inches and really bushy.

at the 4th-5th set of branches inspect the tops for signs of pre-flowers,they will show before you put in 12/12,but its difficult for some people to see them,white hairs are female and a stalk n ball are male...and indoor they will stretch out so you can put then in flower now but it may not kick in for a week or 2,start feeding them higher p-k and cut back on nitrogen,this will trigger the plant to start flowering as some say...

good luck
