Aquarium Dwarf Hairgrass Seeding Question

would seeds such as Dwarf Hairgrass seeds sprout and grow in a tank that already has water in it? I planted seeds and some root tabs into my tahitian moon sand sub but I forgot to keep the sand moist. I put some water in it just enough to moisten all the sand. though my buddy is coming with the water I need for the tank in a few days. from what ive heard it takes longer than a few days for them to sprout.

 

They need a few weeks to get to a mature size. Rushing the water could cause them to rot and it would be a whole waste. Maybe you should just tell him to come back later.

 

I was watching a video of some lady who flooded her tank after placing those cheap seeds. They grew perfectly fine, the only thing she did was pour them right on top of her substrate. She also had a nutrient rich substrate, which you might need. I think it took 2 days for them to sprout.

unfortunately had already invested in the 40lbs of sand which is already in the tank , and wasn't smart enough to do research on planting a carpet in sand. though I did read some reviews of people having plants in it. obviously that's not the same as growing though T_T thought maybe the root tabs would help. I didnt really think out my seeding process though. I kinda just flattened out 20lbs of sand and covered the front row with seeds and then dumped the second 20lbs on top of it . the sand was still a little wet from washing it so I thought that would be fine. but I haven't seen a thing and its been like 3-4 days I think? I don't really count the days anmore. today I did the treated water thing to moisten all the sand. I can only hope something happens

 

Not exactly "dwarf hairgrass seeds" but I tried some carpet seeds last year and they are not what they are advertised as. I just sprinkled the seeds on top of the substrate and went through with it like a dry start method (moist substrate, covering the tank with clingwrap & 12hrs light). Mine sprouted after 5 days.



It looked good in the beginning, but they got bigger after a few weeks and turned out to be hygrophila polysperma (I'm lucky that I didn't get some terrestrial plant that will eventually die submerged).


Eventually, I removed most of it and retained one that is still in my tank today

 

I doubt what you’ve got is really dwarf hairgrass, but sand should be fine if you spray some liquid fertilizer on.

I should have just bought some seeds at my LFS, does this fert alter the chemisty of my tank at all? and can this only be applied in a tank with water in it or is wet sand fine?

I don't believe LFS's would sell seeds either, I've never seen anyone grow dwarf hairgrass from seed. Usually it's bought in-vitro. Fertilizers, depending on what you get, only affect the compounds that is in the fertilizer, usually nitrate is impacted a little bit and most other compounds we aren't able to test for. It doesn't harm anything. Wet sand is fine

 

update: I bought some liquid fert on amazon which I didnt know existed(thanks mak) should be coming in on wednesday. hopefully its not too late

I got the liquid Seachem Flourish stuff. but its not a spray bottle its one of those drop a capful things. should I put it in a spray bottle?

You could pour a single dose in a spray bottle and mix with a little bit of water, and spray that. I wouldn't put all of it

just curious what is wrong with tranferring it all to a spray bottle?

 

Personally I would like the ability to easily dilute it depending on the tank. Also, the cap is usually the measuring tool.

 

stuff smells like soy sauce

Quicker contamination if the spray bottle is not sterile

I agree

I bought one of those plastic ones from the dollar tree

I suppose if you want to pour in just some of the flourish you could, but you also wouldn't know how much you're dosing with a spray. It's really hard to overdose flourish because it's quite dilute but it's good to know how much you're using.

ironicly I only needed the spray bottle for the moist sand to fertalize it and hopefully ill see some green in the future. its been like 5-6 days and nothin. I probably won't be using the spray bottle to add flourish again

update: its been a week and I see no signs of anything growing, thinking I should have just not planted anything, now I fear my fish and water are going to suffer for it when they move in. I should stick to buying plants

ps: what do I do now that I'm pretty sure the seeds won't grow? pretty sure I won't be able to pick them out easily since its like a needle/haystack situation
