    sometimes plants to that when they need water but thats probably not the case with a hydro grow so idk really. unless your watering schedule isnt right.
    Everything i say on here is for fun, and mainly to talk with ppl like the guys from Cheech N Chong. any attachments that i upload are found on google or youtube.

    im pretty sure it was my temps, at one point it was almost 35 celcius (95 F) thats crazy, i have them under 600 watt hps in closet (my metal halide burned out today) and with the bulb I notice higher temps, gonna have to keep my closet/ velcro poly film open a bit until I rig up an exhaust fan.

    I am not sure my PPM I ordered a PPM pen last week from ebay it should be here any day now, but I changed the water today and added a stronger growth mix. 3 tsp per gal grow, 2tsp micro, 1 tsp bloom per gal. (added 10 gal tub vs the 5 gal they started in)

    do fans really cool it all down that much, I mean if the closet is sealed? I figure I should just move this to the laundry closet, that way i can tap into the dryer exhaust duct. I already have a 6" inline fan and some ducting, I only have it exhausting to the bedroom right now, but it definitely needs another exhaust fan the 6" inline don't seem to be cutting it, i don't feel it blowing very hard. lol
