Thanks everyone for the encouragement and kind words.
I am so proud of myself for discovering how to see all the threads a member posted-----I always enjoy hearing/especially seeing what others are up to.
I made an aero cloner / early veg out of this 2' x 2' Botanicare tray, lid and dome------added a meter for temp/rh inside the dome.
3/4" bulkheads for supply and drain lines (quick connects) also.
I tried lots of different spray line configurations-----can't say which is "best".
Notice I used that blue "cobra line" again-----great little part-----can be found Lowes/HD in the lawn sprinkler section----available in different lengths and diameters.
The lid I ordered with no holes drilled------made a 7 x 7 grid of 1-3/4" holes that 2" neoprenes snugly fit into-----NO NEED FOR NET CUPS.
I ordered a pack of critical kush seeds through attitude and started them in vermiculite cups described earlier.
Once the roots were this size, the vermiculite was rinsed away with water then to sink and sprayer for the remainder.
This is how they looked in their new home under a 2' x 2' 8 bulb T5-----just the right size for the tray.
Closer look-----notice anything missing?
Under the covers.
A feature I discovered by accident:
Since there no net cups and medium-----the stems can be adjusted up/down in the inserts for a level canopy.
Another part I like is that inline valve in the supply line. Without it----seems like every time I peeked under the lid I'd get blasted.
Just used a trash can (grocery store) for the rez monitored by a tri-meter.
Used a Large submerse able pump with the 2" cross technique for a filter.
Pump timing set to 15 seconds on----15 minutes off.
