Hardening off plants

[Macncheesehaze]

So is this super necessary? I Have a bunch that are gonna be going out side soon and where I have them now there’s no way I can put them outside anywhere for any Amount of time.

 

[Macncheesehaze]

Plants will have been topped twice by then and be almost 2 months old.

 

[Dark_Hatchling]

Yeah it pretty much is.

The Sun is so much stronger than any artificial light you can buy. They'll get a wicked "sunburn" and likely get roached.

I'm not sure where you're located, but here in Nor Cal, its getting very warm, bright and sunny. It would definitely harm their little virgin leafs.

Can you even get them in the shade or some heavily diffused light?

 

[Macncheesehaze]

Nah I live in a building, if I put them in the window the whole block would see them. I have two mars hydro ts 600s on them in a 32x32 about 20 inches away. I’ve had these lights burn plants before. More than once unfortunately . Seems like I might just have to hope for the best, or when I move them to the spot just keep them in the shade for a few days before I put them in the ground maybe. I was thinking the temp change would Effect them the most. I’m gonna start trying to make it just a little bit colder in there. Wind is no problem fans are always going on them.

Temperature isn't that much of an issue
But the suns strength and angle in spring is why you harden them
The "putting them in the shade for a few days" should do the trick
Be careful you have enough hours of light before making the move

 

[Macncheesehaze]

Yeah I’m pretty in point with the light cycle. When I put them out my tent light cycle and the suns cycle will be the same. There’s spots deeper into the room that get sunlight stretched across it. Would that be enough?

Spent 30 bucks on some agraBon or some shade cloth give them three days under the agrabon or shade cloth and you’re good to go

If you can't harden them off properly before moving outside then at the very least setup some sort of shade for them for the first few days, possibly cover them at night if it gets cold. Just try to minimize the shock however you can, they ought to manage then.

2 month old indoor plants will die if you stick them under direct sunlight, trust me I learned this through experience many years ago.

As others have said, do yourself a favor and buy a shade cloth. That's really your only option, if you don't do that don't expect them to survive.

 

[Macncheesehaze]

Someone else mentioned a window, I can’t put them in the window by I have gigantic windows that get tons direct sunlight. I can’t put them right on the ledge but a few feet back on the table would that work?

 

[Dark_Hatchling]

I'd be looking to shade them somehow or diffuse the light.

K.I.S.S

 

[Dark_Hatchling]

K.I.S.S

Yeah. Exactly. It doesn't take much. I've done it successfully multiple times now without using any strict method.

Just take it in a few steps, and you'll be surprised how well they respond once they get that real sun.
I just put my 3 photos out yesterday, that I started from a weak light, and they are fine. One is noticeably bigger too.

I was hardening off a few off my plants the other day in preparation for the next few weeks plants going outside etc ...


This was her first time outside I only meant to leave it for 30 minutes then bring it back in but I fell asleep on the couch plant was under sun for like 3 to 4 hours and shes scorched!

Hardening off is not only important its mandatory !

 

[hipressure]

But I do feel like depending on what your light source is sometimes the plants require more or less hardening off seems to be that way but I am.no expert my plants are under hps and mh /t5

I feel like some plants can just power through it obviously but in my case it bleached my leaves in hours!

When my plants go outside I will have 15 hrs of light so I have been trying to match that daylight to prevent early flowering


Cloudy days are perfect for this and the plant does not need to be in direct sunlight obv .


Cant wait for transplant time ! 2 more weeks !

 

[hipressure]

This plant was a tester plant anyway just to see how the hardening process would go ...(male )

If you need to put photo plants out early, get some cheap solar lights that come on at dusk. They are way too weak to help them grow but are enough to extend the photo period.

 

[Macncheesehaze]

So again I just want to verify. Will sticking them a few feet back on this window won’t do it? It gets tons of sun light.

 

[roaf]

I put them under a tree in partial shade for a few days. Then move them out into direct sun for an hour and increase by another hour each day after that. After about a week or so of doing this and they do fine in full sun .
