humidity domes

[shadycon]

This the reason I start my seedlings a couple of inches low in the pot/cups. The ones that I have planted this yr., I've already finish filling the cups up

Afternoon pic. Going into day 2 with dome on. Looking like the right color. I suffered the green algae of death last week. lazy me, clean clean clean.

4 to 7 days is typical for dome removal as that's when roots have formed but venting the dome prior is good practice.

I've just lost maybe 10 seedlings. I don't want to see any more. It's traumatising me.

I use fruit juice containers and now I would have removed the lid from it which I read drops the humidity from 100% down to about 80%.

If you have lowish room humidity I'd be putting more holes in that container. Good room humidity, say 70%, you can probably remove the dome

After a brief refocus on my next grow and education from the minds of GWE I got one That just popped, Auto. As it stands its been up a little over 24 hours above ground. Humidity dome is still on for now. Ill take a pic again when she finds the light, got bent searching, had it in semi dark. Is now the time for it to stay off.??

Thats what i have done wrong this grow start. Had a few suffer the green algae of death. Learning. They look so good and green and then its over. Grow and learn.

I can't remember ever losing any recently, last 10 years anyway, once broken ground, but this grow I have lost one after another..think I've lost 8 or so.

First time using H²O² with a soak under 12 hours in 200 to one solution then into papertowels as normal.

Never again!

[Bowhunterwoody]

Same here. Never left them on more than a day. Never lost one after breaking ground.

[Going2fast]

I take them off one day after breaking ground.

My stalled seedlings all showed a yellow fringing on the first true leaf, size anywhere from 3mm long to about 12mm was the largest.

It didn't matter if the coco had only water to moisten it or a tiny nute wash that was EC 0.15, same yellow fringing and lime green on the rest.

The collies looked healthy till they started to curl. Domes I use are good and ventilated them on first leaf, 4 to 7 days from breaking through the coco.

I blame the H²O². Got another 10 seeds on papertowels without it now and will see how that goes.

I'm experimenting with clear cups for domes. Also when planted into cups I fill appox. 2/3 's full , as new plant starts to stretch, I keep building it up to support the plant.

[crucialbunny]

That's the very reason my domes come off with the second set of leaves. I then will keep a fan on low to help strengthen the stems. Sometimes they stretch during the dark hours and I find it's necessary to use a bamboo skewer to help support them. It's been my experience that in soil they probably won't need to be fed until transplant. Looks like you have plenty of perlite so you shouldn't have to worry about over watering either. I think what you're seeing is a bit of algae and that shouldn't be an issue once you remove the domes. Have fun -

I have been using humidity domes with my indoor grow routine. I started this grow just like all others that have worked, Still learning. This run i have developed lime green edging on the seedlings. Think i have left the domes on to long ?? Searched a bit on forum and site but nothing runs with the look. No nutes yet. phed water new seedling soil.
