Light bulb holders are only like 2-5 bucks and you could get a 60w or so full spectrum led bulb and that should be good Sent from my iPhone using Tapatalk

I don't think so. If that's the only light you can use I'd wrap the bottle with it. I'll find a picture. Someone did it for macro algae Sent from my iPhone using Tapatalk

Mines at 1.022 For nannochloropsis it's 1.022-1.028 I believe Sent from my iPhone using Tapatalk

The only way to do that would to make a glass table and put the light under it. But I kinda don't want to spend money so this should be okay for now Sent from my iPhone using Tapatalk

There I used boxes for now [emoji23] Sent from my iPhone using Tapatalk

Yea I was actually planning on raising it so the Petri dish can slide right under and the light shines on top. I just got it yesterday from my dad's work aha. It was just laying around. I've been busy so I haven't had time to build something to hold it up. For now it seems to be working. It's a...

Day one on new batch: Phyto already started to create a lawn Sent from my iPhone using Tapatalk

Update on cultures FLASK: PETRI DISH: The rest of the agar culture aren't growing so I'm only keeping the one that did and two others just in case. The rest I discarded For the new batch I used less f/2 and less agar Then seeded it with a very concentrated amount of phyto obtained from the...

How much of the phyto did you put in the bottle? I bought a 8oz when I first started mine and I poured 4oz in a gallon container so it was pretty dense when I first started it. If you use less it would take a couple of days to get a green tint. I suggest leaving the light on 24 hours for he...

Update on agar culture Sent from my iPhone using Tapatalk

that's fine I'm using a 1 gallon jar and I have 5 of them I think it's better to have multiple small ones than just one big one cuz if one crashes you still have the others. Sent from my iPhone using Tapatalk

I took apart an old emergency light and bam instant filter for any camera [emoji23] Sent from my iPhone using Tapatalk

Idk I'll test that out with the next batch. I have access to an autoclave from my teacher and my neighbor. Sent from my iPhone using Tapatalk

Yeaa they use this method in labs to store strains of algae You would have to close it air tight to keep the agar from drying and store it upside down to let the water stay on the surface instead of the bottom of the agar. I read it on a research paper. I'll try to find it again and show you...

I was thinking the same but then I saw this on eBay. In the description it states that one disk is worth 16oz of phyto...

Hopefully if the culture gets dense enough, to feed you would pour fresh saltwater into the Petri dish to dilute the phytoplankton and allowing it to be poured into a bottle while leaving the agar gel behind Sent from my iPhone using Tapatalk

The culture would actually be growing on the smooth top surface of the Petri dish so wiping up the algae without getting any agar would be easy. If any of the agar however does break it won't hurt. Agar's chemical formula is C14H24O9. That means it's a carbohydrate. Since it's made up of those...
