most of those lights have 660nm red leds already' adding UVA and violet light will improve taste and potency but you can groq without them.HPS has almost no vtolet or UV but still grew well

I learned a lot from you about T5s from you. what LEDs are you running?

diodes have a logarithmic. response curve. a 38 volt strip would have 12 diodes in series so a 0.72 volt difference would result in a 10 fold difference in current

Iconsidered buying their "1000 watt" unit for a test grow in a 2ft by 2 ft closet.they are not as efficient as the white LEDS everyone here is pushing but they have a much better SPD including violet and a little UV. then I read the reviews. the first one said 4 rows of diodes went out after 3...

no I have not my training in electrical engineering tells me this is a bad ideal. the data sheet does not provide that information.it does show a negative temperature coefficient so thermal runaway is possible when operated near maximum power with the heatsink being used.

running in series requires a higher operating voltage producing a greater shock risk, running in parallel can result in one strip pulling more current than others. electrical engineers use ballast resistor when operating simi conductors in parallel to prevent this imbalance.many of the people...

running in parallel can cause problems use a constant current driver and run your strips in series to avoid imbalance

nice!!!!!!!

those strips can be run up to 700ma without a heatsink however it would not hurt to attach each strip to a 2 inch by 4 foot strip of aluminum

interesting way outside my budget

Iam a PU MMJ grower.I have been growing my own medicine for 6 years wit T5s 5 years ago I started using plant bulb instead of 3000k for flowrig and saw an improvement in yield https://www.amazon.com/dp/B00FQ87DP6/?coliid=I2GA9WD8U48GW9&colid=AW7UKM9ED6GM&psc=1&ref_=lv_ov_lig_dp_it i recently...

2 of these should work for you https://www.digikey.com/product-detail/en/mean-well-usa-inc/HLG-120H-C700B/1866-2354-ND/7703910

just be careful about fires. open well ventalated area away from flammables and reduce heat to slow boil while cooking off the alcohol. people have burne down their homes making this king of extract 190 grain alcohol is extremely flammable

at 700ma 10 strips will produce 50000lumens (6250lumens 16 watt radient power per sqft) that should be more than enough I am using 324watts of T5 in a 2ft by 4 ft tent and getting good results so 273 watts of LEDS should be more than enough.this driver should handle 10 strips...

it is done when making e-juice. mix the infused alcohol with coconut outdoors away from anything flamable brin a pan of water to a boil on an electric hot plate place your mix in a wige mouth container and place this in the boiling water until the white steam stops and you no longer smell...

I'm a mmj patient and cannot smoke so i use green dragon with 10ml of 190 for every gram of cannabis.I put 3 ML in a cup of hot tea and don't taste the alcohol. the alcohol seems to help me absorb the THC

meanwell drivers. and I would drive those strips at 500ma more efficient,less heat and more than enough light 36000lumens

if the plant is absorbing the light I assume they are using it for something. UVA helps plants absorb calcium from the soil which may explain the cal-mag deficiency seen with LEDs. the 365nm LEDs I found on amazon have an efficiency of 4.5% (1200mw input 55mw output) with an instant start...

what is your budget for lights?are you into DIY?

just providing evidence that spectrum matters. the power veg provides half the photon output of a standard bulb with better growth. for a low budget PU MMJ grower T5s work well. they outperform cheap ebay LEDS
