  1. If the uvb diodes are too warm like hes sayijg isnt they sealed in were csnt get wet or anything coild add air fan systems to that were sir constantly flows across em an pulls the warm hot air air out an fresh cooler air in thst runs across inside space with diodes an ya they already make custom lights make an custom air system that pushes hot air out diodes area an pulls fresh cooler in with tiny smaller inlines fans an ya dont the new vivosun vseed have 2 in it ones pulls fresh in other exhausts same concepts but in led light in space we're diodes are an sealed area add fans on both ends that os connected to light bars an pushes pulls air through lights n would be common sense dont spray the ends were fans are n should be spraying ya lights anyways n if done right moisture wouldnt really get in either an or an tiny drain hole ever so often were if does can run out one them stead staying insides but just dont spray it an if lights for flowering only really wouldnt have worry about moisture in the air getting in

  2. @fromthestash an CLtv google "does day vs night temps cause stretching in plants" an says yes if your night temps are 5 10 degrees cooler at night causes stretching an then says if nights temps are even same as day limits stretching to minimum an then says if nights temps are 5 10 degrees warmer at night stops all stretching an doesn't allows any plants energy go to stretching an instead can go to bud sites an terp trik productions an is number factor for stretching in plants with lightning being 2nd an is combination of the two and is important in all stages of growths why seedlings are better off at 24 24 were isnt any night temps an stays same even limiting any stretching and ya same with his strain been growing for yrs cltv in veg could keep it short an tighter an ya most important in seedlings an flower cause in flower if say 25 30 35% of the plants energy is going to stretching unwanted stretching at that its robbing energy thst could be used going towards bud sites an terp trik productions an ya google it aint saying lighting dont effect it too but is combination of lighting with day vs night temps an think the night temps vs day is number one factor cause people be having there lights dailed an still get that unwanted stretching in flower an then blames the lights or if there dails ooo then its genetics or certain phenotypes noooppppe its there night temps in flower are 5 10 degrees or more cooler at night an isnt whst ya want in indoor canna plants an ya woild be better off at even same night temps than cooler but even then still sun energy is going to stretching an why they have these newer heater for tents isnt for cold places or lung rooms its so can keep nights temps least 5 degrres warmer at night during flowering an swazzzying heavy defolilating removes all any leafs except newer smaller ones right rd flipping day of or next day an then again day 21ish 22ish or mid week 3 of flowering main purpose is boosting sending signals to ramp boost flowering hormones an ever thing else is bonuses better air flow no micro climates an pathenongens an better wind stress deeper light penatraiting deeper an not have so much trim at harvesting annthen makes trimming way way better less time consuming an easier an ya the uv issue there uvc predator lights are true uvc 4ft long an comes pair 2 for rd 120ish bucks an for 4×4 an 5×5 spaces an post runs it only 1hr day at night anndont effect plabts light cycles an ya only for ipm an pathogens resistance an hoes in bottom facing up similar to undercanopies an guess could mount tops pointing down too but think they recommends bottoms an ya there only for pest pathogens resistance an removal getting rid em an then for flowering want uvb florescent an most all are 2ft versions but is also 4ft ones an brands making the uvb florescent 4ft bulbs think brand arugo or something can finds em on wally world's app search for uvb florescents 4ft n ya rd 56w an want ya want needs just search finds 4ft florescent plant light thst also 56w an get the bulbs separately get more ones too cheap an case one or 2 comes broken is shipping least have 1 goods ones an if dont have extras an ya swaps the bulbs ya selfs there ya go prolly coild even get dual bulbs fixtures made for plants same wattage whatever an use 2 the uvb florescent bulbs in same fixtures were stead of only one at 56w or even 2 at 112w could have two dual fixtures pushing 112w eaxh 2×4 space so 4×4 5×5 could have two dual fixtures pushing 224 225watts of uvb power an start rd 30 45 min intervals day n slowly raise to 1hr an 1hr half an 2hrs an then 2half an finishnlast week or 2 rd 3hrs n day an thennlast few days before harvesting ups it to more 3 half hrs cause heard can get by with 4hrs day but they may not be case just start low 30 45mins daybearly flowering an depending on wattage an coverage of the uvb florescent would depend how much per day wsnt give em n then just raise the times slowly 30 mins ever 4 5 days till get first week 2nunder its belt an jump intervals up to 1hr per week so by week 5 or 6 ya maxed at 3hrs day an then weeks 8 9 last week or few days raise from3hrs 15mins day till at 4hrs day biut 4 days an leave it at 4hrs till chopped alps helps flips ya flowering lights back 18 6 last week or even weeks an 2 weeks isnt enough for em start revegging an ya ya ge fine even last 2 weeks 12 14 days going back 18 6 an never do darkness at ends only creates new unwanted CLEAR triks that will does change the final products medical effects for the worst an makes people flip out an concentrated make it even worst an ya dont do it only light on at very ends so do 24 48hrs lights on beforehand before chopping down never do light off an blame 420 scene for spreading the false rumor an still this day promotes says it like wtf its been proven wrong an only makes new clears triks an ya theres reason ya wait for the triks turn from clear to couldy milky at least before harvesting an never want harvest clear unmatured triks an then consumes then never ever an ya also dont want add then in at very ends either bad very bad of read this entire comments hit the thumbs uo buttons here comment an the vids 🤣 🤣 🤣

  3. Cool stuff. I use timed UVB in an array of 25w bulbs as a pest prevention and ripening tool. It will burn your skin and requires uv glasses but not as dangerous as UVC. I have UVC flashlights that I've never tried.

  4. Hey blurple was the greatest to me as it added that extra uv that I see is definitely a plus after not using it. Actually that's the only reason I liked them.

  5. Could someone please let me know if anyone has ever put lights on the ceiling, walls, and floor to get light under the leaves and everywhere really? Never mind, i watched the rest of the video and got my answer.

  6. What if there was a system that has different phenotype environmental setups? For instance. The environment could be set to Oklahoma weather vs Ohio weather and verified breeders and companies enter this data into the system for each genetics in their specific environment indoors & outdoor. The app could tell you about what that cultivar likes or hates.

  7. 3:19 man I feel for him and his family. I have stage 4 metastatic melanoma and I’ve fighting this beast a while. Almost died a few times, seriously, but cannabis has helped me a lot through all this. I’m excited to get my 1st grow started very soon

  8. Thanks for Another informative and entertaining show! I use the best grow light of all, the Sun. I watch your episodes just because I like listening to you guys, I grow one time a year outdoors in Michigan.

  9. UVC is produced by the sun, but earth's atmosphere blocks most of it. I love the under canopy lights. They stop the need for lollypopping as much, so you get a 10% to 15% extra yield.

  10. I got my 1st pound plus n a 5×5 using dry ice for Co2! N under canopy!!!! Used an old mars hydro fce-4800 for undercarriage n had a mars hydro 8 bar fc-8000 on top.. 😅o forgot i had 4 Uv45 bars .. so that’s a 12 bars poor man “Grand master Borg”😅

  11. Hey bro I didn't hear your cousin's name yet and that would help because I'm a follower of Christ and I pray a lot. I'm going to pray for your cousin I just wish I knew his name cuz I'm pretty sure that helps. But I trust in God that he could cover all of the cracks in society plus an infinite amount more

  12. Thank you for the community that you built and tried building gml. I'm sure you didn't get a lot of subscribers because back then people were afraid of getting in trouble for even subscribing to a YouTube channel because if they had a homegirl and they like the YouTube video about home growing they were afraid they would have cop show up. I know I'm one

  13. Gonna have to buy me some stash blend, and I’m on grandmaster discord I have been hearing some good things and he is a stand up dude , very transparent and honorable man from what I have gathered so far. Right on fellas thanks for the share, ✌️

  14. Maybe 10 years ago we had this hand held uv light that you would hold over a plant if it had PM. Want to say sunlight works made it. But it definitely killed PM if you used it for correct time. Interesting hear it could be used for IPM

  15. Somebody get this dude on some rooted leaf agritech!! *most nutrients are the same, but not these. If you are serious about chasing the BEST you have to have the best.

    He needs to see there are innovations in ALL areas of growing. Especially nutrients. It’s a shit show re sell china market. NOT rooted leaf. 🍃
