If you can't get a pH tester, I'd at least get a roll of pH paper and some pH up and pH down solutions (or baking soda and vinegar, respectively). Problems I've had with my current dwc grow included problems that I believe started with a high pH (my test paper showed a color that looked like 7- I had chlorosis and leaf burn, wilting, on old growth). Deficiencies start to show with nutrient lockout, which can begin with a pH higher than 6.5 (read from GC!). I added small capfuls of vinegar until the pH registered at the 6 color spot on. Vinegar, only because I'm on a very limited budget at the moment! Oh and Id put in a fan too. peace

i got 4 bubble buckets setup and ready, cant fuckin wait but lemme get this straight What does a EC meter exactly do? i got a ph and tds meter but i didnt know a ec meter was mandatory under 250ppms for seedlings and than the ppms should gradually rise week by week? oh and is that 250 ppms of nutrients? like say the water from my tap is 150 ppms...i put nutrients in till it reaches 250 more? |

hey hey. Ok ive had my seedlings on drippers in small pots with vermiculite. they sit in the lid of my bucket. they are almost 3 inches tall now and i think the roots are ready and long enough for me to change my system to a bubbler. Any idea what meduim i can use instead of rockwool or clay pebbles? I say this cuz here in south africa its almost impossible to find. I know i would have to change to meshed pots but not sure what medium i could use. Any advice? Cheerz |

another good idea is to go to ur local fish store n buy a water pump and tubing and a splitter the splitters come in 2,4,6,8 holes so they work good and make a drip system insted of having the water just sit on the bottom it help move the water with the airpump and keeps the neutrients from settling to the bottom of the resevior
