"forgive me here... Im just trying to wrap my mind around this level of production in a small space under lights.. because, if you can produce that much basil indoors.. Im impressed! im guessing these are not 1 lb cases?"

"try Maximum Yield.com,,, but the main reason, IMO ... Ganja is one of the few options that justifies the means. Joe.. I would love to see your set up! 50-75 cases of basil / week must take quite a warehouse full of T-5 lights. I could use that much…"

Hi Rob. I have been using goldfish and koi in my system that I started one year ago in SA. I would like to add in tilapia this spring. I was told I might be able to purchase some from you. Is this correct?

Have you ever worked with anything vertical or towers? I just got my tower in over a month ago and its way sweet!

Do you prefer gravel over rafts?  Building a setup similar to yours,  just dont want to do it twice.  Never tried rafts yet,  it seems i can grow more in gravel tho.

Hi Rob - it looks like you have a large operation, how many people work with you? Do you keep track of your total output? About how many square feet of growing space do you have?

Cheers

Hey rob thanks for all the info and helping me dial in my system.The fish are doing great and  I plan on building that heater tomorrow.My wife and I really enjoyed the tour of your facility.your input was spot on...I learned more from you in a couple hours than I have in weeks searching on the net.

Howdy Rob, It's John Fullerton, I've been away from things as of late. I hope life is treating you well.  Awesome post on the heater.  Just saying hello and checking in, nothing major at this time.  Still working on getting the greenhouse built and finished.  Still want to come down and check you out sometime and just working on figuring out the time that's best.  Life is super busy.  Take care and talk to you soon.
