why don't you just use a bit of soil and put the seeds on. So then once you have some roots there, just gently run the plant with soil under the water tap and clean the roots. You have to be gentle with it, but I've done it.
SpaceNeedle Reviewed by SpaceNeedle on . I need some hydroponic help... I have an aeroponic system, everything is set up and ready to go, i have my pots with grow rocks in them, problem is.. I dont have any rockwool cubes to put the newly sprouted seeds in, can I place the the seed and the little root directly into the grow rocks? or inside a cotton ball? can I use a spongue instead of rockwool? I dont have any of those little cubes, can I still do this without them? there must be some easy alternatives Rating: 5
