Kat_Rigel Posted September 28, 2020 Share Posted September 28, 2020 Either you have it and want to get rid of it, or you want it and can't grow it. 😂 For me it is the latter. I have read multiple online sources for how to start a greenwater culture, but it's not really working out. First, I am too cheap to go and specifically buy Mircacle grow fertilizer (I would use a pinch for this greenwater culture and then have a bag leftover.) I DO have a different plant fertilizer, Scott's slow release fertilizer, with a 10-10-10 ratio. Do you think this would work? I tried using old aquarium water with a bit of lettuce in it, outside on my balcony with no aeration. (3rd floor apartment) It became a gross goopy slimy mess, but no algae. After 3+ weeks I called it a loss. I am wondering if my balcony just doesn't get enough sun, but I've managed to grow a really tough pair of pepper plants (like, I stopped watering them and they survived the winter in Northern CA.) So it seems like that ought to be enough sun, right? Hornwort and other easy plants are growing ok in my makeshift 29gal pond too (also on balcony.) I am using a rather small container for the culture, like, maybe a half gallon, if that. Is this too small to start a culture? Space is kind of at a premium so I would rather not place an entire aquarium out there. What is the best way to start this culture? I do not have access to a starter culture. Should I try tank water and an algae wafer/fish food? Take a field trip to a local pond or lake for a sample? Tank water and the fert I have on hand? Could you do it with Easy Green or other liquid aquarium fert? I would think so, since there wouldn't be any plants in the water to compete for nutrients. Aeration? No aeration? Artificial light? (I would think the sun is better.) What has worked for you guys? I'm not in a particular rush but am expecting some fry in a few weeks (I hope!) and it is always nice to have on hand. Plus I'm kind of on a live cultures/fish food kick lately. (I'm eyeing daphnia next, but one step at a time!) Thanks all! Link to comment Share on other sites More sharing options...
