| A raft system is perfect for lettuce...I have all the parts except one thing...
Are the white styrofoam insulation sheets from HomeDepot/Lowes safe to use? I have seen them used before, but are they safe around stuff that is going to be consumed? -j- |

| Hi, If you haven't started building your system yet, take a look at how lettuce did in a simple to make system using 2X4s and a plastic tarp. To answer your question, I have used a lot of styrofoam with good results. Only problem I had with it was that algea love's it, and it tends to get covered with it quickly. You can also see how I used the styrofoam in the pictures on the link below. good luck, chuck |

| Swimming pool noodles! Buy a noodle and cut a bunch of 1.5" disks out of them... The tricky part is figuring a way to bind two or three of them together at a time. Once you've done that, just keep binding little clusters of them together until you’re satisfied. I don't think they would be stable enough on their own. That could be a way to go? |

| That’s a very unique & refreshing idea, rugby10. Maybe they could be tied together with nylon ties. I have seen them both available at the dollar store, as well as large containers that would work as a mini pond. You could get a whole setup for about $3.00. Remember when growing lettuce during low light times excess nitrates can be absorbed. |
