A plant without a functioning root system and sitting bare will benefit highly from sh a high humidity environment assisting in safe guarding the plant from exhausting its reserves in bulb storage. Its leaves absorbing moisture through cells stomata, a good supplement as far as its choices go anyway until it realises it foliar water intake is insufficient and instinct sends out new roots. Not sure on a bare foot rootless plant with psbs and prolonged water contact though with rot issues so high risk.

S/h for a plant with functioning roots will be down to experience of other members with this plant also and a general bout of advice for s/h dabblers. Are the plant roots oncid/ dend like- thin whitish and wire like as i know Zel. O s are.? My Zel is mounted bare to cork and sprayed daily x1 or x2 in response to days weather.

S/H cultivators please intervene. Will give your thread a bump later.
