Anyone affiliated with Mars Hydro? Very disappointed with customer service
My TS 1000âs controller/driver crapped the bed. Contacted customer support, told them the issue, they diagnosed based on videos i send, and was told they were sending replacement parts. 2 weeks later, no email confirmation and no reply to my previous 2 emails sent a week apart.

Is that possible to do grow light with Samsung LED strips?
Going deeper into idea of doing the quantum board from scratch but instead SMD LED's there are lots of strip LED options. So I want to ask you guys if I have an aluminum plate with a heat sink and coolers, can I fix those stripts there? Or can I rip them off with a heat gun?

Shifting outdoor plants from outdoor to indoor
So I was wondering if outdoor plants(week 2) getting regular sunlight (~12-13 hours) can be shifted indoors for faster growing (18/6 or 24/0 or 20/4)? Anyone tried before? it is safe? Will it cause to make them hermaphrodite?
