many growers believe that HPS will produce higher yeilds but MH OR CMH will produce slightly lower yeilds but better poiency and flavor. recient studies indcate the higher UV and VIOLET may be the cause of this. as a PU MMJ grower that can't sell what I produce. I prefer MH,CMH.or T5s but a...

once you get the power set right it works well with herb. have not tried it with wax or oil and you need to let it cool before removing the glass top or it could crack.

https://www.fasttech.com/p/8002500 good for vaping herb or oil

looks like this is for vaping oil. several kids got sick vaping infused e-juice so this may be the only safe way to vape cannabis if you don't have an herbal vaporizer

I am current leaning toward these https://www.growlights.ca/t5-led-36w-tube-660nm-red-light-2-pack.html. just looking for a 450nm tube

we don't learn without experimenting

I refer real science to "BRO-SCIENCE" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4030627/ PUBLISHED 2014. LED makers have always claimed that plants don't light that LEDs can't produce but I have seen some nice plants grown with T5s which have very little deep red(660nm)

I have decided to use these to add 660nm to my flowering spectrum https://www.growlights.ca/t5-led-36w-tube-660nm-red-light-2-pack.html

I know about cheap chinese LEDs but they are cheapand they may work for my applicatiom.they achieve those high ppfd readigs by using a very narrow beam angles. for me LEDS are toys to play with and I don't plan on spending a lot on them

Iplan on using them as supplemental lighting to add more red during flowering.. eavh bulb produces 132 umoles at 12 inches so 4 would give you 524 umoles an efficient flowering level. my main light produces a little over 700 umoles so flowering power is not a problem

found something that might meet my needs https://www.growlights.ca/t5-led-36w-tube-660nm-red-light-2-pack.html plug and play solution :):):)

use what you like I'M not trying to convert anyone. for me T5s work great and they are popular enough that they will be around awhile

I've been a T5 grower for 6 years and see no reason to change.LEDs may be good for suplimental lighting and I like playing with LEDS but for a primary grow light I am not interested in any light that can not supply PSII stimulation or UVA to a plant and the only LED that can provide PSII...

looking at the different lights on the market there seems to be no consensus among LED makers. this is a new and evolving technology. in time we may have true full spectrum lights using 385nm diodes driving an RGB phosphor

my 400k bridgelux stips veg well.adding a fs plus uv. seems to improve vegging and flowering. https://www.amazon.com/dp/B07GBRKXPS/?coliid=IQH359VASXSVU&colid=AW7UKM9ED6GM&psc=1&ref_=lv_ov_lig_dp_it but this is a 1 plant closet grow. I still prefer T5s but LEDS are fun to play with.

nice bt what I really need is a 660 nm strip light . my main light is 18 inches wide leaving only 6 inches to work with I tried mounting 3 watt 660 and 630nm diodes on 1 inch aluminum "U" chanels held 1 inch from the main light with croosbars attached to the main light with double sided foam...

I am a very understanding person. don't worry about it

I have stage 4 bone cancer so methadone and morphine only manage the pain. my care giver is helping with my grow so I'm switching to 8 plants in 5 gallon fabric pots with no training and flipping when the plants reach 12 inches to keep things simple for my caregiver

my main light draws 434 watts. I am looking for a way to add more red to my spectrum during flowering. I am currently using these mixed with ny 6500k veg bulb but they only last 8000 hours https://www.amazon.com/dp/B00FQ87DP6/?coliid=I2GA9WD8U48GW9&colid=AW7UKM9ED6GM&psc=1&ref_=lv_ov_lig_dp_it.
