Adding in an LED board for the last 2-3 weeks of flowering?
Duddersstarted 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.

Lamp for houseplants?My neighbours fiancé yesterday evening dropped by and gave me the lamp on the photograph, I have no users manual, but I understood it is for houseplants. I wonder if it is of any use and how I can use it. Whenever the sun shines I will put the plant in the sun of course

Wrong light scheduleScrewed up light timing.
Thought I was on an 18/6 schedule in my tent but apparently it was 12/12 from weeks 3-7. It’s close to needing to be switched over to flowering size wise. I switched over properly to 18/6 two days ago and plan to keep it there for an extra week. Yes?

Light strength2 of my autos have been harvested and now I just have 1 mature plant mid flower and I've started my 3 other seedlings. I've got a tsw 2000 w/310 wts. Should I keep my lights at 100% for maximum growth or should I back off a touch to say 75 or 80%?

How much light - PPFD - without CO2?How high in power should I go with my lights without CO2 enrichment? I can comfortably provide 1200 PPFD to the canopy, but I'm holding it down near 900 because I'm not sure the extra power used would yield an increase in, um, yield.Week 7
