    Yes. Natural reaction for the plant to adverse conditions is droop. So long as everything else is fine it will be caused by too much light.

    how far is it practical to have a meanwell driver dc leads ?

    Ever consider using cat5 for under 50w? You can bond 2 pairs together and run them out a fair distance. PoE is good for 37w using 1 pair I think.

    Yeah those were the ranges for the 4 chambers in the last 2 cycles which is when I started the 6/18 light schedule for flower. I originally intended to increase grow area using the same power per day which by itself can really increase your yield if done properly. What I was surprised with is...

    Would people buy a heatsink that allows water cooling?

    Ah, but if it is worth doing then it is worth doing right! Everyone will find their own starting point and continue their journey from there. I just know that at the end of the journey it will be as many LEDs as possible.

    Yes, they are dialed in pretty well. Indica dominant hybrid and a sativa that I can only run once a year because it fills up my storage limit. I run both seeds and clones, primarily seeds picking out a good plant from 20 or so to take some cuttings to keep going. Since I know what to expect from...

    Rahz' notes and observations

    Notes thread is a great idea. People can try what they want at their own leisure. @ttystikk less is usually more when it comes to plants. How many pictures of overfed, over watered plants have been posted on the internet? Less electrical power, better results. Less heat, the same. CO2 can be...

    Heretic! You want light, not heat. More LEDs is always the way to go.

    Most of you all are paranoid and so negative at times that you fail to see the sarcasm, irony, etc.

    Probably took a hint from HydroFarm :)

    Rahz' notes and observations

    Up to 12 Vero 29 c per square meter now. 400w max for only 6 hours per day in peak flower. PAR meter is an absolute necessary tool.

    Rahz' notes and observations

    My run comparing 3000k 80 and 90 CRI ended up in a draw. The 90 CRI started flower earlier but the 80 caught up during late flower. Same quality in end product, couldn't tell the difference between them. No reason not to mix them up or go with either in my opinion. 90 CRI provides a better...

    I have only been doing this light schedule for a year now with 2 different strains. Before that I was hitting them with light for too long so I think they were flowering as fast as possible back then.

    Cannabis Daily Light Integral

    For me it is pretty subjective when it comes finish time. It might be shorter and I may be leaving them in flower longer as a result. If it is around the time they should be finishing, eg. 8 weeks, then it is a situational call as to harvest or keep going. Sometimes scheduling gets in the way...

    how far is it practical to have a meanwell driver dc leads ?

    You probably have the headroom for any voltage losses for long runs so long as you use the appropriate gauge wire: https://en.wikipedia.org/wiki/American_wire_gauge

    Enough. Probably because I am not selling anything. Impossible? Have you tried it yourself? Don't assume others have your limitations, lots of people like gardening. Officials? You mean the grow bros with youtube videos or a recognized research entity? There are many completed and ongoing...

    It is about the same, nothing noticeably different, a day or two on either side maybe?

    Cannabis Daily Light Integral

    Keep RH down under 50%. I live in a desert area and have lots of airflow. 4 growing chambers for flower each getting 6 hours per day with only one being on at a time. Since the air circulates through all 4 chambers, there isn't really a lights off period where RH would spike. With 4 filters it...

    LED light intensity

    Never throw away a light! You can give them away to other growers if you can't find a use for them. Someone will. Whatever light you got you should learn to grow with first. Then go out and get all fancy to your heart's content.

    Cannabis Daily Light Integral

    For flowering, no extra fr, just the Vero 29s in different color temps. 3000k 90 CRI seems to start flowering faster than 80 but they both finished up at the same time. Yields and quality were the same. I want to try a run with 1750k at some point once some space frees up. Going to stick using...

    First time grow 4 x 8 lighting suggestions

    The only justified response to this is to suggest enrolling in a science program from an accredited university and acquiring degrees in the relevant areas. Generally accepted as a positive social interaction in the real world, unfortunately sage advice on forums such as these is will be seen...
