need advice

wuts gud,
i was told 2 water my plant when ever i stick my fingure a inch deep into the soil n its dry. well i water'd it yesterday morroning and 2day the soil was dry so i was wondering if i should water my plant every day or every other day.

i was told the same thing.. but if i was you id get a moisture/ph/light combo from any garden store like 8-15 dollars
