When to water

[Brwnthmb]

Brwnthmb the green algae is a good sign you're overwatering. Might be a sign of needing fans? A solution is a solution of H2O2 and water. Not sure the ratio. Something weakish, maybe 10% H2O2 - 90% water. Spray the green lightly. Do not soak the soil or you will have a mess, and you will kill a lot of beneficials.

yes I think so (overwatered). Today 6/18 has been 12 days. The surface is getting dry, but I wouldn’t say it’s time to water. My initial soaking of the soil must’ve been excessive. The algae is dying back. Hopefully I won’t need the H2O2 but I’ll keep it in mind.
And the fan is a good idea. I have one but hadn’t thought to use it on seedlings.
Thanks.

You can get the biodegradable ones, DON'T do that!



ductwizard you should try Google from time to time you know.

When you said you “hardened them off” before planting outdoors, does this just mean that you placed the plants outside for a while on successive days, so that they get used to direct sun and wind?

Yes, and the cooler and warmer climate.

So they'd get a few days in a window and then outside in a spot that would get morning or afternoon sun for a few days, giving them a bit more sun each day. Any extremes and they'd go back inside for those.
