Thanks for replies guys,
See-through was a mistake, i start noticing mold after few days, and wrapped it in aluminum tape but skipped the bottom.
will use dark pots after TP
When they were smaller i used to water every 3 days, now
pots getting lighter by end of 2nd day.
I've heard rule of thumb "1 gallon per each foot of growth", but I topped them, not sure if ratio is still the same.
I guess i'll wait till i need to water every 2 days and then TP
