@Donaldj, @peachfuzz, @kabongster Going to use my Food Saver and make ice packs. As far as the roots, I know there isn't a lot coming out of the basket but the one's that are thick (about 1/4") with a big bundle of fine roots at the bottom. Here is a better pic of it.
, This may be due to me putting fresh seedlings in that has a root about 1/2"-1" long, I do not put seeds in starter soil, they go right in the bucket from germination. The water level is right at the bottom of the basket at that time and when I see roots coming out I lower it. (3 gal.water in 5 gal bucket).
I think if I get water temp down I will be ok. I did fine the post that suggest water temp in a DWC system be 65-75f. I will be lowering temp to 62-68f as soon as I get them frozen.
Again thanks for all the help.
