I made it myself thanks to woodprix website
-
So you don't need aeration? Which is great if you don't as my greenhouse is not presently near any power source
-
that foam does not look like safe to use for food. it has lots of chemicals.
-
who plays this song?
-
I have spent months studying home aquaponics and discovered a great website at Keiths Ponics Site (check it out on google)
-
This looks familiar!
-
You may save a lot of money construction hydroponics yourself rather than buying it.
-
this is really good. i was just wondering, can i grow tomatoes using this method? how often do you change your nutrient solution? or is it a one time pour of the nutrient solution?
-
would this material be to small to hold up the pots? I'm having a heck of a time finding the right size for a bus boy tote version.

The presentation... so much better than hearing people hem and hah! Very clear, pleasant music. Thank you.
Information... some really good ideas. Again, thanks! -
The downside of hydroponics is you will need to purchase "plant food" or nutrition and supplements which are more costly.
-
what mil of film do you need?
-
Very cool can't wait to see lots of updates on this!
-

-
Thanks for the info. Looks easy enough to build.
-
Great job, looks great and every easy to build. Love the kraky method.
