Personally, I don't understand the 1/2 full reservoir bit. As long as the wick is wet, water will wick up as needed-weather full res or 1/4 rez. The wick is like a reverse siphon. If you are siphoning gas from your tank, the flow won't slow down as you get to a 1/2 full tank.
What if the roots grew down the wick tube and are sitting in the water?
However, I'm sure your familiar with the old hurricane /kerosene lamps. Basically a wick going into a reservoir. The light doesn't get dim as the kerosene level gets lower. If you want less or more light, you adjust the height of the wickTrue with gas tank but in the Earthbox the lower the water the less it will wick up .....
When siphoning gas you have same size tube to pull gas and you can siphon until tube hits air and when it starts to hit the air less gas comes until you are just sucking air ...... and when the tube is half in gas and half in air it still siphons, just less .....
also when siphoning gas the Gas can is lower than the gas tank - I’ve never tried to siphon gas upward ....
EB is just the opposite it wicks up to the soil rather than siphon down into the can ....
In the EB the lower the water there is less “wick” exposed - unlike the siphoned gas example - and as water is being wicked up the wicking surface is getting smaller and smaller and it has to wick the water higher so the wicking is decreasing ..... water can only wick up so high, believe studies show 8” or so is the maximum Water can wick upwards .....
Wicking goes against gravity whereas siphoning uses gravity,

I'd like to find a more detailed article/video on the design of the earth box. I know it's supposed to "closely mimic" nature but we don't have a layer of air sitting under us. My current feeling is the air layer is supposed to air prune the roots so they aren't sitting in stagnant water and the wick helps regulate uptake of water. I'm pretty sure if you remove the air layer in the earth box, fill it with soil and 3 gallons of water, you won't be happy.Roots do go into the water but just like hydro so long as air is present no problem .... Earthbox is designed so there is an air chamber between the reservoir and soil .....
In a future grow I intend to experiment with an air stone inside the reservoir and see if we can get even more growth .....
Take a look at nature you’ll see lush growth in trees that are alongside the river - half of those tree roots are under the river bed ..... a second example is when we put cuttings into water, they grow roots .....
Just like the river bank trees and cuttings there is some air present in the Earthbox.
Thanks for the offer but living in an rv, I just don't have room. Especially since all my closets are grow spaces now.Oh yea I actually have two nice ones - a double wick and a single wick ..... as you say you lower or raise the wick to adjust light .....
Earthbox is the same, the lower the water level the less “light” or water will be wicked up!
BTW - If interested in my lamps, PM - they are from the Carter Days and in great shape - I even have two spare covers in perfect shape - I would like to see them go to someone who would use!

I'm thinking of trying to use some cloth or rope as a wick which would minimize root growth down the tube. I'm using it in the bottle sip and it's working fine. I've got to make up a box for some tomatoes so I'll try it in that.
I've been thinking of adding the airstone as well. I just need to take the time to find a 1/4" fitting to go in the side of the box(I think I just figured it)
Bye the bye, I'm not trying to be a dick or start an argument. I'm totally new to this and trying to understand it and if I can, help a bruddah out. By throwin different ideas around, maybe we can find him a solution.
One question I do have is: someone said something to the affect that if you see a problem, you are probably a week late. I'm wondering if with these sips if it might even be a longer period? And should we take that into account for things like changing nutrients, top dressing etc sooner when going from veg to bloom? How long does it take for a top dressing to become effective? If I have a problem will foliar feeding give me quicker results? There's a lot of info about setting up sips but very little about maintaining and barely anything-that I've seen about when the chit hits the fan.
That's enough inane rambling for today
