there is no chance that you can replace a 1000 watt HPS with the LED's you are showing in this video, I cover a 6x6 footprint with a parabolic reflector and 1000 watt Hortilux super HPS. you would need two of these LED's to do the same.
Anyone that thinks LED's don't give off heat is misinformed, The infrared these LED's give off burn plants real good, infrared heats up the leaves not the air so it may only be 75 degrees in your room but you can still be cooking your plants.

How do you think the HLG Diablo 300r would perform in a 235 or is that overkill and if so what do you think would be a good alternative? I had the viparspectra P1500 but found it to be a little bit mmmm too little. I was thinking about the Viperspectra XS200 please lend me your thoughts. they both have Meanwell drivers and Samsung diodes, is the diablo R300 too much for the 235? Thank god I spent the last 3 mos studying or I wouldn't have understood a word ya said!

I really appreciate your show man you've answered a lot of questions for me I am actually getting started and a little bit of a beginner I know just enough to be dangerous I used to have a 500w HPS which when you walk in the room looks like you were walking on the Sun but also put out a ton of heat. I totally just nerd it out on the video man just let me know when you're ready to give away a light I will totally take one because I am shopping right now

I am growing spinach, green and yellow beans, beefsteak tomatoes, tiny tim tomatoes, large cucumbers and long stem green onions. Which grow light would work. I am currently using my storage room. It gets up to 22 degrees celcius with the light on and 19 when it's off. The humidity is between 50 and 60. But my tomato leaves are changing to purple and curling down and my cucumber leaves seem dry and turning brown at the tips.

Liked. Nice clear breakdown: ).
6: 16. I'm petrified to touch any of my CMH bulbs bare handed, not sure if the exploding bulb thing is a myth but I just assume not chance it. Philips is a great choice btw, we've used budget CMH bulbs (Vipar, iPower, Chinese etc. ) and the light output from Philips brand is obviously different. we've been 2 years on our latest set with no measurable dimming

Great video but you should never touch a CMH bulb with bare hands, always wear a cloth glove or use a clean cloth or even a clean sock if you have to handle it. It should have a warning right on the packaging saying so. Even a small amount of oils from your fingers can create hot spots that can even pop your bulb if on constantly or not passively cooled during long periods of operation.

Very informative video thank you! QQ: What's wrong to heat up the growing trays by the grow lights? Where I live is cold and dim in the winter which means I need both light and heat to start seedlings. I understand dispensing heat means the energy is not being converted all to light. But maybe there is a balance there that I need bfor where I live?

Yo these LEDs are pretty expensive up front. I got a decent yield would of been better if I didnt pack my grow area.
And made sure to lollipop and trimm. Frosty tight buds Very potent just didn't like the bud size. 1lb golf ball size and 1lb the size of marbles.
Wish I lollipoped and trimmed. This time I'm doing 10 plants instead of 32

just a lil tip you really shouldnt touch the cmh bulbs with your hand as then some oils of your hand get transfered to the bulb wich can when it heats up break the bulb or just start smelling badly so to help with the longevity use a kitchen paper or maybe even gloves to put it on. just so that no oils get onto the bulb

I just want to grow two tomato plants, cherry and San Marzano, and six or seven herbs, the usual for cooking. Growcraft sounds as though it could be of the best quality, but any one of ChilLED's would be ridiculous overkill. I'd like to spend $100, or 200 for a light that'll last a lot longer. Any suggestions?

Simplified. 125 dollar Lithuania 80 cri, 4000k, 126 watts LED high bay from Lowes. It's the best light for growing in veg and flower. Super high on the blue end and super high on the red end. It's near perfect. Pics to prove it. O and this is for a 3x3 tent. 3 to 4 medium plants easy

Oh no, the Prism Lighting Science HO T5 V2 4'4 bulb was discontinued on the website. What would you recommend that's similar?
I have a balcony garden (in Southern California) that's under a large tree so I'm hoping I can get more light my plants.
Thanks for your help/advice!

I only raise seedlings using mine so I have 5 metres of 4000K LED strip chopped up to fit in the particular shelf unit I use.
30 watts over 0. 25m2
Absolute efficiency is not very important as it's usually cold in my house when I'm using it.

Ive been using the iL8x for the past 6 months and i couldn't be happier. I dont know why they're not so recognized but theyre one of the best out there. You get what you pay for, the quality is extra good and not enough people know about them!

The best bang for buck is full spectrum LED Quantum Boards. This stuff is too complicated for starters. Forget this just go buy simple Mars Hydro, Viparspectra P series or Artreum Hydra. All about the 175 - 200 $ range
