what up mineralz yeah it is day 28 from seed good guess bro! your grow is lookin great dude. you wanna know something man whats weird is that on this board tons of people state that the rez water cannot exceed 70 degrees or Ill get root rot and so far nothin (cross my fingers hope this doesnt jinx me or I'll look stupid) , cause my rez is like at a constant 80 degreees and so far so good, but then again I dont know much of long term damage but just wanted to add my amateurish 2 cents, one thing I can definetly say is that the mycorrhizae i believe is beneficial because I have seen nothing but good results so far , My roots are getting thicker by day.thanks for watching mineralz and all who are watching.
