first grow

hi this is my first post. ive just started my first grow and wanted advice if im doing it right.
i got a 8foot by 4 foot by 7 foot high box inside a garage.
its lined with white matt reflect plastic
im using a 600w sodium light. ive got 6 shiva cuttings that are in rockwool and i planted them on saturday in biobizz.
i watered them when they was planted but as yet not watered them again
the temp is 103 max and 60 min. humdity is 80 max and 35 min.

am i doing things right or do i need any guidance

:jointsmile:

i think 90 degrees is the highest you want to go

Thats an extreme high, and an extreme low on your temps. Definately want to maybe try and get it around the 70s.

how do i get aound that problem? with a desktop fan

put in a bigger intake and exhaust fan
