Add about a Tbsp of salt to each 2L bottle. It will get to a lower temp when frozen and last a lot longer before it all melts. I use pickling salt in mine but I doubt it matters what kind of salt it is. I believe it's calcium nitrate that farmers fill their tractor tires with for weight and to keep from freezing but I'm not positive.
Its 4", and the ones nearer to the rez are just getting out the end
Its probably best if you stick with the plant size you are working with now, the tubes will pack with roots. You should try to get decent size feed/drain lines, if you don't already, so they don't block up or slow flow. Its a great way to grow, you just have to work the kinks out.
Pretty much have to work the kinks out of any style grow lol
That's a universal law I'm sure, its a hell of a crash course. Reminds me of going to college for years just to realize none of the book work matches how the jobs actually done.
College hell... all the way thru school! Anything past reading, writing, basic math, and science, all useless in the real world. Lol
They need to teach money management, emotional management, leadership, cooking and home care, shop class, and gardening during middle to high school. The world would be a better place lol
Preach!! I was fortunate enough to go to a high school that had agricultural science course, mechanics,and one of only like 3 I think in the country that had meat cutting class lol
Michigan schools are like heres a prison to go to, with 20 year old text books, and if you are one of the good prisoners we let you take shop or art lol. Trying to figure out who thought it was best to keep all these basic life skills from the kids.
Agreed.
U.S. government!
