ok once again how large a container do i need for large tom

is 25 or 26 inches deep enough will 18 inches work it will be in hot weather this spring i was looking at a 24 x7/8 in by 18 7/8 in x 25 in deep tote think it was 26 or 28 gal nice look i read up on als soiless mix, pretty impreseive read think ill use a bit of a variation for my conditions weather wise. found a mulch supplier in phoenix that may have pine or fur fine think ill use coconut husk instead of peat or with a litte peat thats in a kelloggs soil amend ,with ill throw in

some perlite and or granite small stones i wood like a lot of imput from folks with tomato contanier experiance please.and either speculation on my growing conditions i do need a sun screen for riping toms in late may to july here or plants will burn fruit setting will probabley stop by early may. my fall toms are now in a 18 gal tote i put 1 betterboy and 1 bush goliath will be frosty in late dec so i figured i would need a whole lot of room my 12 inch goliath bush has a small tom now, it must have set in 90 to 95 degree weather who'da guessed. i need some inut on containers from u folks in hot summer areas please ive got to get this right for the seeds carolyn sent me i was so stoked over that neves azorean red seeds she sent me i think so highly of her. i was like getting a song from elvis. thanks again carolyn .
