No roots!

Hey space or "help needed", or any1 following this rockwool/hydroton debate, i have a question! from what i understand, going straight hydroton > rockwool/hydroton combo, BUT, for those of us who feel compelled to combine them, would you suggest CHOPPING the bottom portion of the rockwool cube right off AFTER the seed has germinated? I've got 2 babies who cracked this morning, and I want maximum flow of oxygen to the roots, and i feel as though the rockwool will indeed mitigate the flow of oxygen to the roots, especially in the plant's early stages of growth. if i could just transform the rockwool cube into a rockwool 'plate' of sorts, problem solved, no? Thank you!

I think instead of chopping the RW plug, it's much better simply to place it in the HT in such a way that it does not get wet from the system, and therefore avoids the stem rot pitfall. RW starter plugs should be hand-watered for seedlings and young clones, so that they don't get waterlogged.

Good freakin lord, folks- just think it thru...

Place rw cube on top of hydroton.
Hand water rw cube. Water will pass thru cube, cascade over hydroton.
Roots will grow out of bottom of cube.
Roots will grow thru hydroton.
Roots will emerge from bottom of net cup.
Roots will grow down into solution.

You will need to hand water the rw cube about once a day for about a week.

Not rocket science.

Don't overthink.

rw sitting on top of hydroton will not hold water for as long as rw sitting on a dinner plate. Rw on top of hydroton ( or otherwise able to drain properly) is actually kind of tough to overwater- excess runs out the bottom, if there's a place for it to go.

You're right Rhizome, this conversation's getting kinda silly. I'm quite finished now ;) :jointsmile:

:S2: gotta good laugh outta this one... Ive grown in rockwool and hydroton in the same net pots. like said earlier hand water untill the roots pop out of the pots then your in bussiness

OK! WTF????????

I still have 2 plants that have no tap roots showing no side rooting no f'n nothin!

Now i have 1 plant that has a tap root coming out of the hydroton, but it's growth is less than that of the plants with no roots!!!

Someone help please!!!

If you only have 2 plants... do as suggested, just hand water once a day until you've got roots coming thru. Man, you should have roots by now... unless you've been leaving the rockwell cubes so wet, that your plants are drowning... what EC/PPM are you feeding them?

If your plants still aren't growing, something else is wrong. Go to the top of the Plant Problems forum and fill out the trouble shooting guide and post it in the Plant Problems forum instead of the hydro forum. You'll get more visibility that way, and you'll get answers from people who actually know what they're doing.

what i've noticed is that the LIQUID KARMA that I use covers the roots you currently have in a black ... stuff and as soon as that happens, the roots just shoot out in every direction and plant growth follows suit:thumbsup:

i use rockusing canna rizotonic or reganaroot.these products are gold to make good root structure.try these and see lots of white root.even use rizotonic as foliar spray on cuttings.for real mate you try and see.if using areoponic propagater only use for 15mins per day using tank heater or heat mat to sit tank on.if this helps you let us no.peace gman corby town....uk!!!!!
