Ive always just aimed for 6.0 and have been perfectly fine in standard potting soil.Anyone have any numbers for optimum PH in a sprouting medium? How about advice on initial nutes and ppm for a sprout ? I could use a little input. Thanks.
If where you are growing is going to be 250 degree's you don't need to worry about the PH because your seeds will never sprout and any plant you put in there will die. Usually you don't need to add any nutes or anything for at least 3 - 4 weeks.
Also, to germ my seeds I just put them directly into the soil, or in your case rockwool, and keep the soil warm and moist around the seed. They usually sprout with in a couple days, the longest it's taken me is a week.

If those are what i think they are, your burning the tips.
Those gel cups are sold as a rooting medium, they are filled with nutes, hormones, etc.
Germinate your seeds directly in rockwool cubes, using plain water for 3-4 weeks
At that time you can plant your cubes/plants into soil or a hyroponics system.
If using soil, you can go another 2-4 weeks without nutes "depending on its quality, and if it came with extra nutes as some do"
If you go into a hydroponic system, simply start with lite nutes, and increase slowly, keep Ph6 and youll be fine.
Testing PH of soil is done with a probe, or using runoff water (but not the first cup)
I know for 100% certainty that the gel is your culprit if thats what i think it is, ive used them to clone many a times the damey

Flowgrow - thanks but the rooters (I have used them before and intend to do my hardening off in them) will break down at 250 degrees. Nothing is guerilla style, I simply cannot open the container until I am ready to take the primed growing tip. I can not add anything, it has to be fully self contained until it reaches the growth point I am looking for. I am giving up my sucrose route and this is why I have come here where people such as yourself have had far more experience than I in starting seeds. Please, if you would, come visit my grow journal so that you can see what I am up against here.Forget using shitwool aka rockwool.
Have to PH and even then if you do it right it can still cause PH issues.
Use Rapid Rooter plugs instead.
Totally inert coco fiber by-products and not "organic" like you're thinking.
Never have to PH, just moisten with you preferred substrate and plant the seeds or clones.
Even breeders like Subcool use rooter plugs and not shitwool !!
It sounds like you're doing it guerilla style, so you HAVE to add certain things to your planting site.
Go with something that's a mild feeder/week medium, then let it get stronger as it gets deeper so the roots can adjust as they grow into it.
For instance, even Subcool puts his young plants in a milder medium to start sometimes, with his Super Soil at the bottom of the pots.
Again, going from weaker to stronger so the plant doesn't burn.
Good grow vibes to you, Canndo !
And a bountiful harvest !!
exactly correct!!!Just use plain water, pH'ing is only necessary for the uptake of nutrients, which seedlings dont need.
i'm a coco grower, which is hydro. i don't feed until around day 11, which is usually when i have 3 alternating internodes. they do fine....Depending on your medium, hydroponics without nutes for 3 weeks sounds like epic fail to me, soil not so much at all depending on how "hot" it is out of the bag.
