I do know better than to stare into the sun but thanks for the concern.
Just trying to be a good Gypsy...
As to the fan, no, not yet, but I will have at least a few weeks to ponder and research and of course look for the best prices. Never know who has a fan on sale.
Smart.. being in a hurry will cost you extra bucks...
The VORTEX brand of fans is considered to be of GOOD quality with eithr a 10 year or lifetime warranty...
There is also a another real good manufacturer of TOP QUALITY fans called SOLER & PALAU
My partner has a crappy six inch in inline fan that I'm sure I can borrow just to have some air flowing through the light.
I am not sure what you call crappy, but I use the ECO PLUS brand of fans...
They work good.. mine are 6 months old now and have not missed a beat... and they are considerably cheaper (also read considerably LOUDER)
If I had the money when I got mine, I would have gone with S&P... or even the VORTEX..
BUT.. I gotta say I am happy so far with the ECO PLUS..
I also use their 185gph and 256gph water pumps... depending on the tray I am flooding...
The hydroton I use on top of my soil, forgive me, but I read where plants won't grow roots right up to the top of soil grows because the top of the soil dries out too much and too often to support roots.
I am stepping out of my realm a little here...
But I will give it a shot...
Roots will grow where there is moisture in the medium...
If part of the medium dries out, so will the roots in that part..
You find the top of your pots have no roots because it dries out...
Now...
I know for a FACT that good potting soil retains much much more water than the hydroton...
How do I know?
Well how often do you water your plants in soil..?
2x a week..?
What happens if you water a soil pot everyday? the plant will suffer...
With hydroton filled pots, I water them 6x a day.. and have done 12x a day...
if you did that with soil, you would have killed all the plants by drowning...
...
Does that make sense...?
Now... I have a few rose bushes outside, in pots of dirt mixed with hydroton... to AERATE the soil... but I gotta water MORE OFTEN, because the clay holds very little...
...
What I think maybe happeining in your case, is that the layer of hydroton is acting as a barrier to the moisture... helping keep it closer to the top...
But that is just a wild guess... I have no proof or experience in this... sorry...
So basically the top couple of inches is a waste, so I tried hydroton and low and behold when I pulled the males I checked the root mass and sure enough the fine roots were near the top of the soil.
OOOps ..
I guess I got ahead of myself there..
In my pots of hydroton, I see roots within the flood zone...
Every square inch of airspace gets filled with roots...
Everything above the flood is woody, dry root... just a conduit, no absorbing properties...
I also saw a picture of someone who had used it in the soil. It is supposed to hold water and nutes and also give your root system nooks and crannies to explore.
Nooks and crannies... aiespaces... but I doubt the moisture thing...
About the only thing that wil lhold more water than soil is straight up RockWool...
I think we can make some pretty educated guesses here... even consult someone if we get stuck...
but I am not sure how important this is... as long as what you are doing is producingthe desired effect, I will consider it a seccess...
I'll try anything to see if it helps.
That is a scary sentence...
Let's use the kitchen as an example... (I love to cook)
Let's say you have never been in a kitchen before (grow op) and all of sudden you feel like eating a cake...
You spend hours looking at the pictures in the cookbook (RIU)... trying to decide what KIND of cake you will have... (soil, hydro, aero)
When you decide on a recipe ( I recommend a simple cake to begin with) you will gather all of your ingredients and follow the recipe...
IF you follow the recipe accurately, you will end up with a cake...
May not be the fanciest cake in the world.. but there is no denying it... it's a cake...
Bake a few "standard" cakes and you will get a feel for how this baking cakes work...
By the time you are on your 4th or 5th cake, you have enouh experience to look at another recipe and say... "oooohhhh! Almonds sound real good with my cake..."
So you bake a cake with the extra almonds in it..
When the cake is done, you will be able to tell the difference between this and the other cake.... because you already ate a few of them, you have a solid basis for comparison...
If the cake does not work... bake another standard cake... if it comes out right, you will know that almonds are not compatible with your recipe...
Is this making any sense???
Use a known recipe... and your very forst cake will be delicious and pretty...
Try to do like a 9 year old and just mix a bunch of random ingredients from different recipes all at once and you will have a big mess in your kitchen... and maybe some weird batter to munch on...
Find a recipe... and follow it...
Follow ONE RECIPE, a proven one... something you can see other people doing with the same results...
Something OBVIOUSLY REPLICABLE...
Then.. all you have to worry about is following the recipe...
Follow it like there is no other cake in the world... follow it ignoring any and all advice outside of the recipe... subtitute only with ingredients approved by the master...
Do that and you will have a grin that you will not be able to hide...
But, there's plenty of people that like to "create" their own recipe... though I can't imagine a very good cake the first few tries...
By the way, thanks for the tip about the fan pushing air through the light.
No problem.. every little bit counts...
If we can make our equipment last, we are saving money...
Edit. I saw the diagram of the ebb and flow system and my partner says, I can make that. You gotta' love plumbers.
Sure you can do it... it's easy...
But I meant did you see this..?
How do I make an ebb & flow
hydroponic system?
The goal: To demonstrate the construction of an Ebb & Flow hydroponic system.
The system being constructed is small, however the design is the same as larger systems.
