once had a dog named
cool.they are in 40mm rockwool cubes,
40mm cubes weigh 5g dry, 25g when properly damp, not wet.i think that they may be a little over saturated but they dont feel like it to me(im NEW)
Whether a tupperware or a humidome, it's not needed if the plant can get water through the stem cut.yes a tupperware thats all i had, walmart didnt have one.
Eliminate the underwater stem cut. Not necessary. If the water isn't sterile, it's a pathogen vector. Ignore dire warnings of 'air embolisms' in cuttings. It's a practise florists use for cut flowers, not real useful for propagation.ya i sterilized everything, i cut them off the plant then put under water and cut again then into rooting solution then into cubes.
Just cut with a sterile scalpel, dip in rooting powder (yes powder- gels can harbour pathogens, powders form a paste which stays put through several waterings), knock off all excess powder, leaving only a dusting, and plug in the cube. A heat mat will improve your strike rate dramatically.
Probably too much radiant heat. A clone without a root system has a hard time picking up enough water without applying a lot of light or thermal stress, both which increase the transpiration from the leaves. Clones need very little light intensity- they just need enough light to be convinced it is daytime for 18+hrs/day so to remain in veg state. Get a CFL or regular flo over them.ahh ya they went into about 4hrs of darkness and under a 400 hps that puts enuf heat to keep the area plenty warm(closet)
Go back over my post about cloning in rockwool. If you follow that like a cookbook recipe- to the letter- you will get 100% strikes in 6-7 days.
I think you may have got the beginnings of pythium/fusarium stem rot- the underwater recut could be the culprit. A humidome will not solve the problem. However, all is not lost. You can re-cut your stems, dip in rooting powder and plug back in the existing cubes you've tried to use once before, but the cubes will need to be treated with a sterilising solution, 50% H2O2 @ 1ml per litre of solution, pH adjust to 5.8. Drain the cubes with a salad spinner or with a snap of the wrist so they weigh about 20-25g.
Watering clones in rockwool is really hard to get right, I certainly acknowledge that. The best way is to dip only a corner of the cube in a watering solution. The cubes really should be quite dry (lost about 1/2 the water weight, cube wt about 15g) 12 hours after watering. You'll have to estimate the weight of the cutting in the cube if you will be trying to manage watering by cube weight, but it's a sure way to make it work.
