Ha ha..sorry I got interupted....
I saw you asking about the air-block...
1 of the large ones.
Placed in the Top 1/3rd of the pot..because I want it for the germ/tap root.
Give them the oxygen/energy to Dive to the bottom of the pot.
See the first photo..I'm putting the pencil through the side of the pot to make a hole for the air-pipe...
handy with the polystyrene pots.
I turned the air-stone on it's back...coz I figured that when you water all the water and compo particles would clog it up...when you water from above.
put a good 1/2 inch of perlite below it..right across the width of the pot..
and 1/4 inch above..
Thinking that the perlite would have a lighter density that the moist compo above and below...
so the oxygen would spread across the body of perlite creating an air pocket..right across the surface
Before it penetrated the compo.
I put them on the air at the same time as the water when I go to the beach in the morning.
Dual hook-up.
I can see/feel a difference in the top layer of compo...
and although the main drying effect is directly above the air-block...
I can feel the difference right across the surface..
The compo is Puffed..has lots of air...
a top Crust that drops when you water it...
So..the equipment is doing it's job...
just gotta see if it Does make a difference.
BTW..I added a non-return valve on the plant pot umbilicus...
with it being in the soil..
I didn't want anything nasty travelling back up the air-hose and contaminating the Pump.
Just trying it out teflondummy..it was FullD's idea..he saw it in another thread..I Think.
When I harvest..I'll have a look at how the roots have reacted to it..if they have moved towards it or away..
and I may amend it then..on the results...
IF it is Good..I may add another air-stone into the bottom 1/3rd of the pot...
and use the lower one as I think the roots have hit the bottom.
Couldn't miss it my friend, there is something interesting going on there.
Now that i have this i want to take a shot in trying to burst that.
Got a sewing needle just for the job.......if it contains scent ill be able to pick it up on the needle.
I was thinking along the same line...
thought if I could get a pair of the fine pointed/surgical tweezers in and Nip the bubble..
IF it IS terps/essential oil..
I would be able to smell it.
E Rosenthal says THC is odourless..so we have a fine definition point.
