Mold on Grow Rocks and Soil surface

I really need some help here fellas. I have some dutch passion blueberry feminised. bought a 10 pack and was wiped out by pythium. bought a 5 pack, this time mold on the growrocks, transplanted in new growrocks, net cups and sterilized system. after a week of non growth, i decided to check the roots and that damn pythium again. I cut off all the pythium infected roots and transplanted into soil. the plants are growing slow as hell now. and i just noticed a layer of that damn mould layered on the soil on one of the pots now. i bought serenade. i've been using it but apparently its not helping but so much.

i dont know what to do. seeds are expensive as hell. im so desperate that im trying to get these plants to grow so that i can get clones off of them, even knowing that pythium is hereditary.

im not new to growing. i just havent grown since i moved to a new location. ive grown numerous crops and clones of sensi seeds northern lights and hashplant. im wondering if there might be a mold infestation between the walls here.

my temps are floating around 80 degrees give or take. the humidity is low. in the 40's, i know its low but its the best i can do and im actually grateful its that low, i could only imagine the severity of the mould if it was higher.

sounds like you are fighting a never ending battle. unless cleaned with bleach and/or replaced, you will always encounter mold in your enviroment. also the strain may not be as resiliant too mold and/or infestation. sulfer burners are ideal though i do not use one (yet) numerous growers say when used properly they do not effect taste or quality. i also heard that co2 lowers the possibilty of mold/infestation. dry ice is good if you are strapped. hope this helps.

edit: blue berry yeilds more with the FIM technique. its a must.

Pythium Root Rot (Pythium spp.) is similar to Rhizoctonia in that it causes damping-off of seedlings and foot rot of cuttings. However, infection occurs in cool, wet, poorly-drained soils, and by overwatering. Infection results in wet odorless rots. When severe, the lower portion of the stem can become slimy and black. Usually, the soft to slimy rotted outer portion of the root can be easily separated from the inner core. Species of Pythium can survive for several years in soil and plant refuse.

Thanks for stopping by guys. I seem to have two problems one being the mold and the other being pythium. I am waiting to order an entire HydroHut setup that will allow me to completely seal the room and control the environment.

I've read probably every possible article written on pythium and for some reason I have this crazy idea that If i can nurse my plants back to health that I might still be able to cut clones off of once infected plants. I know they say that sick moms will pass the disease off to clones but I've ran a few successful grows of Sensi NL with plants that were pythium infected (of course I didnt know it then). Plus the fact that I spent over 250 dollars on the two times I ordered the Femanized seeds really kills me. Im waiting for my damn taxes to come back just so I can order some more seeds. It sounds pathetic I know. This time I will have no mistakes. I will also post a grow diary.

If anyone has ever cut clones off a plant that was infected with pythium, please feel free to chime in. Thank you.

i did. they didn't make it.
