starting seeds in the house is usually associated with a very small variation in temps ... lack of intense light [like sun] .. and humidity issues ..

hardening off.. to me.. involves the extremes of each ... as compared to the house ...

for me.. in MI .. it usually involves protection from night cold ... but for you it would also involve day heat ...

and at 90 degrees.. i start wondering about tiny seedlings in small cell packs/pots ... which could dry out in a flash .. so you are then dealing with.. sun.. temps.. and water availability ..

are you suggesting.. that once you move them.. you will abandon them at a cabin/cottage .. or will you be staying with them ...??? because aftercare is imperative ...

will you be planting them??? .. we probably need more facts ...

and you do understand.. that hardening off.. involves both temp and sunlight and perhaps lack of humidity??? ... you can not take them out of the house into sunshine ... have you considered this???

more facts please ..

yes im hardening them off in the shade outside at the moment, they have almost two sets of true leaves, they seem pretty used to the wind because i had a fan up to them indoors, and i'm going to introduce them to sun in a few days, once i bring them up to payson they will be in the ground at my brothers garden, but hes only there once maybe twice a week to water his and pretty soon my seedlings, i think i can harden them off here, but will they be able to withstand the trip to cooler temperatures and be watered once to twice a day? hope thats enough information
