So I'm trying to grow dhg and hc In my fluval flora in Amazonia powder. I've got two 13 watt power compact lights about 12 inches over it. Will my hc stay low or even survive? What about dhg. Will I run into problems with a lack of co2?

You'll need CO2 for HC to thrive. More lighting wouldn't hurt, either.

A DIY setup would work.

Note: it usually takes a couple hours for people to notice new posts.
Yeah... I might be able to manage sugar and yeast replacements once a week...

Sorry about my multiple post....I've had some up for days and had very minimal responses and I just can't imagine them being found after being trampled by other posts. I'll keep what you said in mind.

Occasionally you see a post by somebody who has had success growing HC with Excel (or another source of glutaraldehyde). Mostly, though, people will say that they needed pressurized CO2 to keep it happy. DIY might do it, if you it right. Go with a 1L bottle at minimum.

Or upgrade to pressurized CO2 and permanently fix the issue.

What if I drained it and utilize the dry start method the let it fill in and add another 13 watt light. I can mist daily and add plastic to the top. I'd do DIY after filling so no melting. Could I eventually revert to no co2 without die off ? The problem I have is that I'm limited on time I'll have this tank set up so I'm at a disadvantage.

You would be good if you do the dsm method to fill in because you won't have to worry about dosing co2 or algae blooms. My hc is doing good in my 10g that I'm filling in. But when you flood the tank you'll need a high bps for the hc to adapt since its using the co2 trapped while in dsm. But you can slowly lower the bps later

i grew hc with no co2 i did have a fair amount of light for a 10 gal tank and i would use jobes plant food spikes when it would start turning yellow. i just cut a little disc off the end of the stick and quarter it and place a quarter under part with tweezers

You won't have to replace your mixture once per week.

I use champagne yeast on some tanks and get 9-10 weeks of use without issue.

I have grown HC with Excel and it's pretty easy. This plant loves it and pressurized CO2 in general. I have also grown HC in an area of my tank that gets exposed to high light and air/water depending on my water level, and it grows like a weed you can do this without co2 if you want to have some piece of wood or something popping out of your tank. In my experience with this plant if you want to try no co2 then you need to really lower the lighting on your tank. Growth will be slow but as long as you have lots of flow to replenish your co2 with surface air it could be a possibility.
