Straight H2O won't cause burns. Only stuff in the water, like salts and chlorine. Flat leafed plants won't get water burn. Maybe if you got a drop just right on a trich, pretty much the only possible way to get the refraction needed. If this was the case, my plants would have been destroyed by sporadic showers last week.

Did you put these under a light they haven't been under before? Do you foliar feed, or is it just plain water?

well actually any bubble of water will refract the light when i spray i shake my plants afterwards to break up any bubbles.

well if they have roots i would waid a week and go half strength or less on the nutes, no nutes till they have roots tho. i swear alot of things rhyme with roots.

You need a degree of separation (i.e. a leaf hair, maybe a trichome.) for the water to be able to focus properly. Plus, the water acts as a heat sink, preventing overheating. water is a phenomenal conductor of heat. Think of it this way; when it rains, do you see farmers covering their crops to prevent sunburn after the clouds dissipate? When you sweat, do you get tiny burns? I can't find the actual article at the moment, but this seems to contain the pertinent info. http://onlinelibrary.wiley.com/doi/10.1111/j.1469-8137.2009.03150.x/full

huh you might be right never really hough about it too deep i was always told dont leave big bubble. on the other hand outdoors water evaporates much faster

The sun's intensity is vastly greater than any bulb you're growing with, in terms of energy output. Either way, it doesn't matter. Like they explain, it needs to be somehow elevated off the leaf to burn. I'd say avoid spraying once you get trichs, just to be safe, at least in the light.

hey poly, i got a seedling, i had it inside under a 26 watt cfl and it grew like an inch with its first set of leaves, they very tiny like a cm long. There is a second set of leaves coming, bearly. its been the same size since and its 2 weeks old, out doors now. planted another one and it the same age with its fourth set of leaves, all pretty huge compared to the other. it looks completely healthy for a seedling but its not growing. sorry i got no pics but its healthy. normal seedling... ??????

not enought light add another cfl
could be due to genetics but now the real growth starts! dont worry about leaf size so much as having them now is the time to add more light

@kp light intesity can be the same or greater at certain points in the room bu you are right overall the sun is greater. that leaf looks like a lower leaf so we can probably rule that out

Definitely a bit more light after that first set. I've had that same problem with old seeds. I had to feed it a bit of sea kelp to kick start it growing again.

I was thinking more of a shift to a higher intensity light, because it really does look like light bleaching to me. Maybe the jump from clone light to an hid with no adjustment?

I've tried a handful of small autos that were all done in rockwool while three were done in soil. The ones in soil were planted four days after yet took off like a rocket! In my haste at trying to keep them growing evenly I transplanted the rockwool plants into soil resulting in them looking unhappy and somewhat shocked. I'm hoping they will survive and pick back up in the next few days but I have never transplanted anything this small so soon or from rockwool to soil.
Can anyone give me an idea as to the likelihood of them living, or letting me know if I've just ruined half my crop. Also how long would it take for me to know if they are going to live or not, and the approximate time it will take for them to recover from this. Any reply or experience would be greatly appreciated.

you should know in a day or 2 thy will shrivel up or rise back up. seedlings are resilient tho im sure as long as the light is not too intense they will survive. it really just depends on the roots, i move seedlings around all the time to rebury as they grow, while the root is mainly still a single shoot. once it starts to spread out i stop,l its not good o breaks the roots.

I may have broken some roots.

I clone with a HID...so Are we talking about how moving it outside gave it too much sun? That isn't right either....sometimes seedlings are slow, or they are just extra rooty...sometimes they get stuck in this suspended animation and go nowhere...sometimes feeding them can help..sometimes it doesn't...just gotta wait and see where it goes...but make sure it isn't being overfed or overwatered

That was a response to a completely different question. Not the guy with the stalled seedling.

No..someone had said that perhaps it was like moving a clone that had been under cloning lights, to an HID...and I was just stating that that doesn't matter one bit...People say that the plant will get shocked from the change in environment..but really the reason plants get "shocked" when people plant them outside is because they damage roots and then the plant can't recover with all that heat and wind and sun beating down on them
