Adding in an LED board for the last 2-3 weeks of flowering?
Dudders
started grow question 3y ago
Currently running a 400w HPS lamp. Would there be any significant benefit in adding in a 100w LED board on purple or blurple?

No. Just a waste of electricity. Your 400 watt HPS will be far superior and also be completely adequate.

Wow. Thank you so much for the reply. I have been playing with LUX meter app and my light. I was bit skeptical about the lumens that I would get from the 15W but as it turns out, it receives well enough ppfd. Still skeptical about the spectrum i am having.

dli 40x40 growbox lamp distance problem
hi guys, I have a ts1000 at a distance of 50cm they tell me to lower it to 40cm but the dli would greatly exceed (60 dli photone) the recommended threshold of 40/45. Having a 40x40 growbox, in your opinion, at what distance should I keep the lamp?

Flip light schedule
1 week into flowering and I need to change lighting schedule, complete reversal from night/day due to cold night tempswhen lights are on. Only way to achieve would be to have 24 hours of dark. There maybe an impact but warmer day temps I'm sure will benefit in the end. Thoughts

Light height
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?
