Thank you Michelle. My wife gets all the credit for the site. She spent many hours learning how to design a page and putting it all together. I spend all my time working on the systems!

Aloha Rafters. I hope the new year is starting out well for all of you. I must apologize for lack of participation for the last month or so. My farm and business are growing faster than I can keep up with. I have just finished with some major projects and will have more time for this forum.

One inch foam might be a little weak when loaded with mature plants. I use 2" net pots and they are 2" deep as well as 2" in diameter. The bottom of the net pot just touches the water with 2" foam. With 1" foam half of the pot would be submerged. Give it a try and see how it works. If the foam is too weak or you have other issues you can always double up the sheets.

Chris, . I located a 1inch Dow Blue board at a very good price. Will this thickness work, or is the 2 inch needed for plant health as well as ease of handling.Paul

I too am in the process of designing either a web site or a Word Press forum type web presence as well as a Facebook page. Your web presence is really informative and one that I will refer to in my design :-)

Well done once again ;-)

Fantastic Website Chris...very professional. One of the best that I have seen :-)

Paul, I use 2" blue board.I cut my 4x8 sheets down to 2x4 or 2x2 for ease of handling. My spacings vary depending on stage of growth, grow out cycle and crop. Check out "Hole Spacing" in this group.I use coconut coir for seeding, but I have been testing a new method which I will post the results of soon.

Chris , are your boards 2inch thick? If you took a4









Chris, are you using the 2 inch board. On average how many holes per 4+8 sheet do you use. Are you using the 2inch net pots? What kind of media are you using for your seedling out in the rafts? Thanks Paul
