my 1st indoor tent grow

had a slow start with the weather being crappy but have my viparspar xs1500 going, got the t6 cloudline inline fan hung up, humidifier going, have a osculating fan also going on low speed. got the temp at around 70-78 degree, and humidity at around 80% just for the veg stage and then will lower the humidity down as the weeks grow old... i do have a question though,,, i have my xs1500 light going, before i got that light i had just a 600w purple or burple light.. my question is will it hurt to run both lights? im running 24/7 because im running autos.. and my pH pen just came in so ive just been using bottled spring water, i have well water thats pretty bad so i didnt wanna risk anything and just got the bottle stuff. ph up and down should be on the way. then maybe ill mess with the tap water, but i doubt it lol... happy growing everyone, peace & love & ganja for all!!!!!!!!! p.p. if anyone wants to leave any feedback, imma thank you in advance right here lol THANK YOU!!!!
