rack questions..

[DeesBalls]

Hey all, i am going to redo my rack and i had a few questions, but 1st...

i plan on adding 3'' to the height, so i can add a 7th tub. then im going to get all individual UTH for each shelf with rheostat for each 2 UTH's. and i plan on staining it to match my dressers (since its going in my bedroom.) my questions are....


after i stain it, how long should i let it air out before i put everything together and put them back in??

and what size of UTH's should i get for each shelf? im going to start buying them one at a time and i was wondering what size i should get...

i have (5) 41 qts, on 5 shelves.. and on my 6th shelf i have a 12 qt and a 28 qt for my baby corn and pastel ball....

however i plan on putting the UTH in the middle of the 2 NON 41 qt tubs...

thanks everyone for the help!
