    Does my Northern lights look okay?

    Hey there. Great job for a first time grower, keep it up. You'll learn more and more as you go along so the coming grows will be incrementally better. I would like to point out that based on the first image, you'll likely have a blurple light. The Chinese are happy to describe these as "full...

    Best Top of The Line LED For 4x4 or 5x5?

    Congrats on your purchase. I'm sure you'll see great results. I saw a lot of talk of of the HLG 550 and Scorpion. For anyone else still debating this choice and would like a slightly cheaper but arguably equally well illuminating light, I'd like to suggest the LEDTonic Q7...

    Light question!? Is there too much ??!!

    Hey there. I really don't believe in the magnifying idea for the following reasons: 1. You concentrate the light into a too small area. You would increase the light intensity (PPFD) by several times in a tiny area while reducing PPFD over a larger area. 2. There's no way you can accurately...

    Question about LED QB distance

    Anytime, my friend. I think what he means by: "plants do not care how much electricity in watts that a light uses, how efficient it is, or how much light it produces in total, only the ppfd of the area it is placed in" ... is that a poorly performing 300W lamp doesn't have to be better than a...

    Optic led 2 gen 4 different cobs color

    I agree that the way they designed this lamp, including its diode config, leaves us with questions. I do, however, not think this a major issue. As the photons fall from the lamp they will mix enough to create a somewhat even spectrum when they hit the leaves. Ideally you'd want the same CCT...

    Question about LED QB distance

    ^ Yes, more watts = more light = more light penetration. While it's great that you've understood the concept of PPFD, not everyone does, you have to remember that a PPFD measurement is a spot value. An increased electricity (watt) consumption means that your lamp is putting out more light in...

    Phlizon 600W LED approx 1.5meters over my 1 month old, should i move lights closer?

    The more light, the better :). But without added CO2 and all other aspects of the grow space perfected, it's not really worth pushing the PPFD past 700-800. Light saturation point happens around PPFD 500 and after 800 it decreases a lot.

    When to use UV switches in flowering ?

    My understanding of UV and far red is that they should be deployed during flowering but only for a short period of time. An hour or two a day. UV and far red together is a good combo but far red on its own should primarily be used to "put the plant to sleep", i.e. during the last 30 or so...

    Phlizon 600W LED approx 1.5meters over my 1 month old, should i move lights closer?

    Hey there. Are you referring to this lamp? https://www.amazon.com/Phlizon-Thermometer-Humidity-Adjustable-Spectrum/dp/B0752CL6KJ My experience with Phlizon is that their promotional images and PPFD maps aren't always reliable. Anyway, assuming that their numbers are correct, we should use the...

    Best option under $100 for my grow?

    Yea, I agree, at least mostly. The funny thing is that despite a fair amount of safety concerns, they are still among the better Chinese brands. Imagine how bad the bottom 90% of brands are. Sure, there are a few decent Chinese brands but overall I'd try to find something closer to home. The...

    Need info on what will work for grow tent

    Good stuff. Do you have any preference in terms of light? LED, HPS, CMH? I prefer LEDs myself but everybody has their own favorite. If you're open to LEDs, what budget do we have to work with? For a 2x2' tent you'll need around 100-175 watts of light depending on how efficient the lamp is. With...

    CMH/LED Combo in commercial cultivation

    I'm not sure if you've considered this but would it not be easier to use all LEDs and supplement with small UV (and FR) lights? It seems to me that you'd dilute the little UV that CMHs emit by using additional LEDs alongside your CMHs. If the goal is to give the plants UV, I would consider using...

    Best option under $100 for my grow?

    Hey there! What a beauty of a plant you got there :-). I hope I don't come across like a buzz kill but for a plant that size, a $100 lamp probably won't do it justice. The cost of a grow light usually (somewhat) correlates to how much light it emits, and I'm sorry to say, $100 won't give you a...

    When to use epsom salts in your grow?

    I just experimented with my own nutrient mix. A mix of Yara's Kristalom and Calcinit, and RawP and Epsom. Each substance's weight changing over the course of the grow. I used Epsom during week 0-8, assuming a 12 week grow. I increased the amount of Epsom gradually from X to 2X from week 1 to 5...

    Led - watt per square foot?

    30w/sq ft definitely sounds reasonable but what's worth considering is that this varies based on the lamp's efficacy, i.e. how much light a lamp emits per consumed watt. In your case, your board with Samsung's 301h + Cree XP-E2 should produce an impressive system efficacy of around 2.3-2.6...
