Hi Paula,
Now is the time for all good men to come to the aid of their country.
I reset something. See if this works. The previous emails tonight will
probably be about the same, but let me know if this is better. HOPE SO!!
Thanks for your "Patience of Gold".

covering we got toward the end of last summer. The latest
stuff we got for US $.057 per square foot and the salesman
said he got in trouble cause he should have charged us US
$.057 per square foot for the first covering we bought. Both
covers were 6 mil UV treated non pvc compatible and a US
$.01 per sq/ft charge for shipping.
The company was Eason Horticultural Resources based in
Kentucky. Marcy just told me they get it from GreenTek out
of Wisconsin.
For technical data do not bother with their sales staff as
they do not know what they are talking about when it comes
to issues of materials compatibility and such. Three times
the sales staff tried to BS their way through our questions
and we had a different story from their tech people when we
finally got through to them each time.
In other words we never got completely accurate info from
their sales staff. Even the pricing we got was messed up so
please get names, numbers, dates and times of who and what
you talk about.
Customer service wise they were friendly and tried to be
helpful. The product was shipped promptly and arrived here
by Roadway truck line, a mainstream truck line, in good
shape and packed well.
They do have real tech people who seem to know what is going
on and we got answers from them within 48 hours and they
were customer friendly.
Hope this helps and happy greens to you too,
Marc

Marcy is studying various emitter technology for our garden
enterprise(s). T-Tape is the leading contender as of this
writing.
The discard waste aquaponics water will be used as a portion
of the feed.

Yeah, Marc, T-tape was my choice too. As I remember, It emits at 0.48
gallons per minute per 100 foot. Does that sound right?

That would be the following:
Models
TSX 5XX-42-480 with emitter spacing of 42 inches
TSX 7xx-42-480 with emitter spacing of 42 inches
Operating at 0% slope and 8 PSI inlet pressure.
