i was thinkin if there was some way to like take a square box and submerse it completely underwater then grow a plant inside of it... wouldnt the water all around it keep the room at a nice, constant temperature?

it wouldn't be worth the pain in the ass that would be involved in getting to it

plus the light going through the water at the top of the box would be a lot less powerful

actually wouldn't the light be magnified..a lot. I think the plant would be burnt to a crisp because of the light magnification. Also I agree that it would be a pain in the ass to do, just buy a fan:mrgreen:

Water doesn't magnify light. It refracts it.

My buddy went fishing for 5 hours with his shoes off and pants rolled up. His feet were hanging off the dock in the water.He ended up with 3rd degree sunnburn on his feet and only a bad sunburn on his legs. The water kept his feet cool while the sun was magnified and burning him like crazy.....but he couldnt feel it cuz the water was cool.....think along the same lines with a plant.

Moral to the story....take sunblock if you are going drinking and fishing!

no like dude have like plexi glass one side where inside you would keep the plant, your lights, and like fans, and have the wires sticking through the glass which goes through a 3-4 inch diameter wall of water imprisoned between another plexi glass wall with like air-tight holes for all the wires... imagine having like a 600w hps inside of a box of water, it would be like an artistic thing you could stick in plain view but its really like a hydroponic pot plant. and wouldnt the water like cold-insulate the inner room to a perfect room temperature?

To answer the original question, yes using water as insulation works great. lots of farmers use inflatable water bags to extend their growing season. Submerging a plant wouldn't work though. Air is the first issue I think of. And for the record, water droplets magnify light. large bodies i.e.: lakes, ocean, glass of water, refract light. And Monkeeman...it gets colder as you go deeper because of currents and thermoclines not necessarily light refraction.

ha its a neat idea but no oxygen or co2.....maybe if u ran co2 and oxygen through airstones it might possibly work?there would be no wind 2 so it would be mega thin...:peace:

oh...well now I feel stupid:P but why do people get sunburned worse when they swim as opposed to just sitting on the beach? Does it magnify UV rays or something?

Because water washes away most sun screens and reduces the effective period to about 10 minutes. :mrgreen:

water magnifies.that is why you are supposed to water in the early evening late afternoon....thedrops of water on the plants leaves will act as a magnifying glass and burns spots in the leaf.....

No.
Surface tension holds the water droplet in a paraboloid shape. Thus, any incoming radiant energy will be refracted towards the center point of the droplet, and if the incoming energy is powerful enough (like the sun on a scorching summer day) the focused energy will cause burn spots.

In other words, individual droplets have the potential to magnify small amounts of energy. Water, as a physical substance in its natural form, does not.

i was wrong..........so what.like knowone else has ever been wrong before..........:mrgreen:


very valid explanation.......

Water doesn't Magnafy light, magnification is just the combination of two REFRACTIONS of light (as the light enters the object (for example magnafying glass) and exits the same object.) the magnification is the difference in angle between the light as it goes in and the light as it comes out.

If water 'Magnified' light, the bottom of the ocean would be illuminated to a blinding degree during daylight hours.

I think some people need to have a look back over their physics books.
