i think you'll have to order something... not too familiar with aeroponics... i definitely don't recommend puttin the seed right into the rocks though. rapid rooters are pretty cheap and IMO the best way to go. i think a 50 pack is like $15. if you aren't worried about losing the seed, or have some backup ones, go ahead and try the cotton ball thing. best of luck and happy growing!
GoldenGraham84 Reviewed by GoldenGraham84 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
