Thanks for oyur responses so far but currently I am using no nutes. The seed was germinated 3 days ago and has sprouted in the rockwool. So I am using no nutes yet, however my ph keeps rising. This evening is rose about .6 to a ph of 6.3, so I lowered it using ph down. Tomorrow moring I expect it to be up again.if you top up your resevoir with fresh water like you should be, your ph really should not be climbing like it is. also, everything you add to your water will effect the ph unless for example you are using a ph balanced nutrient like Floranova. as well only add a drop or 2 of ph down and wait a day as too much can have undesired effects on ph.
i would consider 1 gallon/foot a better model.rule of thumb is 5 gallons for each plant.
I have one seedling in a rubbermaid tote containing about 8 gallons of H2O.i would consider 1 gallon/foot a better model.
I know, it does seem too much but I built this for multiple plants. But I am trying just one seed now to see if I can get it to successfully grow. I have 5 fem seeds but I didn't want to plant them all in case I messed up.regardless of your ph, 8 gallons is overkill for even a monstrous plant let alone your seedling lol
you'd think that would be the case, but not so. in hydro, it doesn't take much eating or drinking by the plants to have a big effect on the ph/ppm of the rez. a larger rez helps to buffer these changes, keeping things stable. a small rez/amount can't accomplish this.i would consider 1 gallon/foot a better model.
Oops! - You should have soaked those rockwool cubes in pH 5.0 water for at least 24 hrs. I also soak my Hydroton for 24 hrs in pH 5 water if I have used it for a previous grow.Noob here. Running DWC (bubbleponics setup) like in Rosemans thread. Problem is that my ph keeps rising. Rinsed my rockwool cube and rinsed my hydroton clay pellets. I am using a PH lower liquid from Petsmart. Will that work or is that not a good one to use?
Nice 10 year Resurrection , I like seeing old threads come back a decade later and read What everyone did back then....I'm having similar issues. pH rises every 24 hours. EC was 650 going in. .5ml drops of down daily to stabilize back to 5.5ph, EC stays the same. Plants are growing nice tho.
