I live in the US, all i have is bag seed, but its all from good strains, i never go near dirt weed. Regular Spongues seem to work great, the seeds are already rooting into the spongues, looks just as if i was using rockwool
InspectahEX Reviewed by InspectahEX 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
