My plants always end up the same dead i know that im new to this and they say start with some easy to grow strains but i had my heart set on growing some purple wreck but the whole thing only lasted 3 weeks im fin to order some more purple wreck this what happen as soon as my seeds germinated i put them in the hydroponic system i know u poast to wait 2 weeks for good roots to show but i find this to work quicker they was doin so good after i hit them with sensi grow part a and when is the best time to use fans when they are big or small because i start usein it at the beging of the growth but they was moving real slow but when i turn it off and left the light on 24 hour they started gettin bigger leafs were gettin greener the heat from the grow box was doin them real good everything was good i check my the ph twice a day ontill one day left for about 4 hours i came back they was dead do u think somebody did something to them cause they was just fine before i left
