we're connected right here on this forum aren't we…
i'd also discourage you from growing in chennai…i've tried in mumbai a few times,
it's just as humid, and indoor/outdoor, both are difficult…
outdoor, if you can keep a fan next to your plants all the time they'll grow well
indoors, if you can afford a dehumidifier for whatever size your grow space is,
they'll grow well
not trying to discourage, just my personal advice from experience
if you have a farmhouse property or if a friend does that's more inland and less humid,
give it a shot there. otherwise, i wouldn't advise you to grow or purchase any illegal substance
in chennai, because they're all terrible.
cheers
