I would not take care of a plant for 3-4 months for such a low yield there is a few people who grown in a 5gal bucket it may better for you to check them out.. but still sounds like a lot of efforts for larf

In fact a driver loose efficiency when not running full/near full power

Or just get 6 boards at 200 watt each no heatsink should cost less and provide a bit more efficiency and should be great for a 4x8 tent

Im just wondering but it looks like the leaves are closing in taco shape, are they maybe getting too much light? Just a thought im not an expert

But you will also be paying twice the price.. for a 10-20% better perfomance at most with hlg.. knock off are worth it for many of us.. it has ben documented in many thread on this forum and they grow good and due to a very simple concept: led on a board - failure rate is extremely low (i can...

I like that the item name is quantum board lm301b when clearly its not the diode they are using in their picture.. chinese sale reputation at its best lol.. I like multiple diodes on the same board but I never wanted to commit to such board as you need different drivers for each channel and im...

Where is your pride bro? Selling your soul for a light 1400$ “worth” of cheap old tech light..come on man, return your light, get your dignity back and start again with some efficient LED and have fun like everyone of us.

I think I read that leaf temp should be about 82F for white LED(a little more than the 80F for hps) for maximum photosynthesis as they produce less heat than hps.. dont quote me on that but worth taking a look

And if you are in europe because I saw £ sign somewhere you can also look at the hlg600 sold by an authorized retailer of HLG in europe and you get a bit more wattage then the 550 may end up cheaper too if not too late lol And finally because the HLG product are more efficient and produce less...

Yes for blurple light light vipar you need to look at true wattage or actual wattage from the wall so a vipar900 is probably around 400w at the wall which would mean equivalent to a 400hps this is why your 600w hps kills it no doubt about it

Cost me 400usd for 4 boards with heatsink and meanwell drivers delivered to my door in 2 days from china.. still need to be careful when buying on alibaba as many use cheaper or less efficient diodes on their boards althought in some cases they look almost identical to the real one.. (lm561c s6...

Dont expect a 1000w DE HPS replacement but a hlg 550 is worth about a 8-850w hps in terms of power/yield... if you like to diy look into samsung strips which use the same LED diodes than the hlg product.. anyhow I suggest you hop on the LED section on this forum.. LOTS and LOTS of info and...

Yeah no doubt with the very popular blurple light generation few years ago its normal to be skeptical about LED but comparing a blurple light to a samsung top of the line efficient LED found in the hlg550 is a complete different story.. I can understand skeptisism but saying that 500w+ of...

Relax bud didnt mean to be mean to you What have you seen, where have you seen that? I was just stating that you were incorrect and comparing a hlg550 to a 400whps doesnt even make any sense.. there is tons and tons of thread that can prove you wromg.. if you really had taken the time to...

A hlg 550 will EASILY beat a 400w hps light.. its more the equivalent of a 800w hps - just for the record.. no they dont need reflector wing..hlg used to sale a version with reflector but didnt last very long. Reflector are used with HpS because the light is 360 degrees while LED in the HLG...

Yeah thats a pretty good price if that includes shipping!

Wanted to share some feedback on the chinese knock off.. so after my previous grow I packed everything up to change location.. ended up putting everything back in place for another grow ive been careful with the light but the connector on the board broke up.. on one board it was only the plastic...

Whats the biggest difference you have noticed?

960w of efficient led in a 4x4 - cant wait to see how its gonna work out! Ill certainly follow your grow and wish you all the best mate:bigjoint:

How high is your light from top of your plant?
