Nice to see this
I can give you a suggestion...the inline nozzle, the one where the water go inside the bucket.
If there is too much pressure the water stream will hit the pot. Hitting the pot roots will not be happy, you can use a little 6mm L connection to let the water go directly into the bucket without touching roots.
One more thing is to use a filter, the better you can find. This to reduce the amount of very small particle capable of clogging airstones and reducing their power, increasing the resistance for the air stream. I was using an inox filter like 25µ mesh size.
Use cheap airstones and try each one first. Select only the best and avoid the almost clogged ones. Change them often.
The air-pump you use sucks air from the place it's in....if the air it's hot it will raise the water temp...and vice versa
Then...I wish you all the luck for this run and remember it's always better to grow from cut and not from seed. Better only one cut for run...different strains using the same nutritive solution can go a little crazy sometimes.
ps: why don't you use a forum picture's album to upload images? It's easy and it auto-resize the image
