I have actually heard of the suggestion to burn your lights for 5 hours in week 1 after flooding and increase 1 hour each week until you hit 12. Is that too little light?

Ya, I wanted to at first, but didn't want to go deeper than 5" which is what it's at right now in the back left corner. This is my first experiment (mostly to test DSM and HC Cuba), and on my next build, I will prop the slope up first with lava rocks or foam.

A few thousand folks have done extremely well.

So........

Common mistakes: sealing the tank up too much, it's better that it's not 100% humid, leave some opening, just enough to get a little condensation.
I can grow HC outside in full sun in California's dry weather if I water daily. I have had it growing on my bonsai. Freezing temps kill it though.

Poor CO2 is the most common killer once people flood their tanks, the DSM avoids the CO2 issue, so any one should be able to grow a nice lawn in while dry, but the DSM saves NONE if they cannot grow HC well submersed, which are quite a few folks.
I'm not one of them.
Are you...Tom Barr? If so, you are awesome and I love you.

All kidding aside, I am actually growing some left over HC Cuba scrapes by just laying them over some soil outside (pushed in a little) and soaked in water to test it out. Looking good so far, no growth yet, but definitely not dying lol

6/1: Didn't really do anything. It's been 3 weeks since the initial planting...

Total cost thus far: Still $120

UPDATE!

6/19: A little over 5 weeks in, starting to see some real growth. A good sign that the roots are coming along. Got a slight case of BGA going on the low parts of the substrate. Tilted the tank towards the back to distribute water more evenly.

Total cost thus far: $120

Nice! How long before you'll flood the tank?

I am on vacation in Thailand at the moment. Probably flood it when I get back next weekend. That would put the DSM at 10 weeks. Still need to pick up some CO2 supplies, like tubing and reactor.

Well I was have been one of the ones with little
success. Things were looking good as a DSM.
Then I flooded the tank and instantly created a
brown mess. I have been bombing it with CO2,
and some new shoots are coming through, but
I don't know what is going to happen next.
I am wondering if I should pull all the brown out
and replant HC. Open for comments.

Looks like the algae smoothered your HC. Did you reduce photo period to 4 hours and daily 50% Water change for the first week? I hope I can do better because the growth is amazing so far.

FINAL UPDATE BEFORE FLOODING!!!

7/21 Bought ferts, a large Ista Max Mix CO2 reactor to run inline with my existing Rena Filstar XP3 and a bunch of miscellaneous CO2 stuff like tubing, check valves and drop checker.

Total cost thus far: $200

The HC now covers approx 98% of the floor space. Not misting for 2.5 weeks while I was on vacation actually aided in combating the BGA a bit. This DSM is now at 10 weeks and I am going to flood in a couple of days when I have some time.

love the progression comparison. Glad you had such good fortune with this. Here's to the flooded fortune as well.

Thanks! Few things I learned.

1. HC Cuba is not as humidity demanding as you think. I honestly think it grew better during the 2 weeks that I was gone and did not mist at all. And I live in SoCal where it's pretty dry.

2. I made the mistake of "adding" nutrients by spraying with water from a water change (fish only). This invited the BGA to start appearing and not sure how much I really aided the growth. Use only root tabs or nutrients from aquasoil.

3. Leave a crack in your seal for gas exchange and to let some of the humidity to escape.

4. If you can see water on the surface of the substrate, it's too much water. You can see that there's little growth in the front 2 corners. Those are the low points and it was constantly flooded. Conversely, the back left corner was the highest point and I was worried that it would get too dry, grew just fine.

5. Tilt your tank if you have slopes to get a more even distribution of water level. Only add enough water so that your lowest point just begins to flood.

*jots notes down in his imaginary pad*



I'm flopping between flood or DSM when I start my tank very soon. I might do DSM just to have fun with some yogurt moss. I've done DSM before, but it was meh. I think I was going way too overkill on the moisture content.
