I measured my jug on the weekend. 70F in the sun when it was well below freezing outside. I would expect that it would easily climb over 90F in the summer... or higher. I will be moving the jug away from the direct light as the spring rolls into summer. I only have plants in it so far... I think that with shrimp in the jug that it would need to be more stable. I don't think that the plants need the direct sunlight as long as they get lots of light... perhaps. For me, I'm not interested in having to provide additional lighting.

yep I agree ^_^
All my jars survive off ambient lights from my tanks~ I'm using insane amounts of lights for really small tanks, so there's plenty to share around :D

I've got LEDs that are pretty focused, not a lot of ambient tank light. We have other large indoor terrestrial plants that do well so I think the aquatic stuff will be fine.

yep they will~I grow a lot of emmersed plants too!

I've heard feed back about led (finnex rayii) vs Fluorescent (cfl, t8,t5). And that the fluorescent bulbs brings out better color from the plants. not sire how true that is. I've ordered a led bulb from ebay to test this out ^_^

on the other hand there are pricier Leds that create awesome lighting. But the price tag keeps me at bay.

If the LED is rated for that 6,500k range then it may only be the lux at depth that may be of issue. Any plants with a bit of red might lose some of that colour as the plants produce green instead in response to the lower light level. I have considered doubling up on the light... briefly.

Mine's a Marineland Doublebright, 6,500k I think. Lots of growth. About 1800lux at the bottom I expect.

He was comparing this light with compact fluorescents.

I'm not too familiar with the lux, but I'm pretty sure the PAR and light levels are similar.
I think red plants are red due to a couple of factors, including high light, limited nitrites and iron.

Regarding the OP...

Nice looking Jar! It sure looks a lot bigger than .3 gallons though. Also, is .3 gallons enough for that many ghost shrimp? Won't they breed? Do you need to cycle a ghost shrimp only tank? Thanks in advance!

is .3 gallons enough for 4 ghost shrimps...? good question XD I guess we'll fine out :P I AM keeping 6 adult shrimps and many babies+lots of snails in a gallon tank with .75 gallons of water... so~ it should.

This is how I set up my jars.
they can't be "cycled" as they dont have a filter.
The plants generally need an adjustment period.

I will use a thin layer of whatever substrate. and put the plants in.
usually prodominently low light, small leaved, hardy fast growing stems. then I add a couple of floaters.

In these setup my best friends are pond snails. Depending on the jar size I will put in a few snails.
pomd snail cleans up the tank as well as completing the plant/animal cycle.
food -> snail waste -> plants

I give the tank a month or two before stocking with shrimps. the tank tends to balance itself out by then.
