Light height
GermanGrows
started grow question 5y ago
Hello all I have a mars hydro tsw 2000. I was noticing the recommended height is 24 inches for seedlings. Is this at 100% intensity? That's well over 1000 ppfd by my meter. I thought seedlings could only handle 200-400?

Hang it at 24 inches and power at 25% 👍 don’t need to turn up to 100% until your into flower. Good luck 💪

Light Distance - 3 plants are taller than the others...
Hi all. So I have 6 plants with a 400w HID. 3 of them are about 10-15CM taller than the others. My light is currently about 45CM from the top of the tallest one. Would this affect the shorter plants negatively? Should I raise them to the same level and up the light to 60CM rather

Wondering if doing another defoliatation would direct more focus to the main sites? Also I have three other plants that are about 2.5 weeks younger, so I have to keep an 18/6 light schedule. Would I have to switch the flowering plant to 12/12 even though it's an auto?

I Made a Big Mistake
I forgot the timer open and the plant has been lighting for 2 days now. Normally I have to turn the lights off at 6 pm. What should I do? Should I wait until 6pm? Or should I turn it off and switch to a new light schedule? Photoperiod - 5th Week of Flowering Phase

Comparing My 2 LED lights
Light comparison. Ive got 4 plants in a 3x3 and am currently running the ViparSpectra V600 LED. I just got offered a MarsHydro TS1000 and Im not sure if it's an upgrade or downgrade. I've watched so many review videos and end up more confused. Should I run both?

What’s up guys me again😂 I’ve got my hps up and running and I’ve got the temperature under control by having my fan blowing directly at the light and I’ve added a oscillating tower fan. How can I keep the temps up when lights go off? Many thanks!

Anyone affiliated with Mars Hydro? Very disappointed with customer service
My TS 1000’s 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.
