See thats something i didnt know ... i didnt know that cannabis liked to have a dry/wet cycle kinda like the lighting cycle ?? I figured they liked to be at least a little moist mostly all the time. So now that i do know this ... how long should i let my soil dry before watering it ?? How offen really should i water these and how much should i water them ?? They are in 5 Gal Buckets so its kinda hard for me as a new grower to tell if they are good or not . Have any easy advice to help me understand when they need water and when they dont because they are in 5 Gal buckets the bottom could still be wet and the top dry ... so that throws me off aswell.
As for the sand being toxic ... i made sure that the sand i bought was not toxic , it was processed / washed / siflted sand. Very high quality "fine" sand so i know that it wont hurt them in any way as far as the sand having toxins.
And know the mag didnt offer any alts. it just had a quick little tip section in it that i took attention to. I may just get Mylar and put in on the floor underneath my flowering plants ... would this be a good idea instead of the sand ?? I still do want light reflection upwards on them ... alot of ppl i talked to said that its either that or some sort of lower side lighting ... but again , im very NEW!!!'

any advice is welcomed and appreciated
