Everything Flora Flex

It’s not a room it’s my garage an it’s pretty big with a lot of air circulating

Sorry can’t find it in your pics now but you were buying a filter for your exhaust.
The picture I seen was a dryer f lint collector… Not a filter… Maybe wrong post… It happens… Lmmfao :joy::joy::rofl:.
But if is you don’t get it…

I reached out to one of my contacts to help a bit on this one

The MQ-100 reads spectrum like this (black line) Blue line is mine


The light you own Spectrum looks like this

As you can see the Mq-100 is a bit out of range but I’m waiting for my contact to advise me how much that matters hope to have answer soon… In the meantime here is a nice readme

Using PAR meters for best results

December 24, 2019

PAR meters are an important tool for growers and they provide useful data about the total amount of photosynthetic light being transmitted to the sensor.

LUX or Light meters on the other hand, which are far cheaper, provide data about the total amount of visible light being transmitted to the sensor.

To understand the true value of a PAR meter versus a LUX meter it is important to understand how photosynthetic light differs from visible light. Plants “see” light differently than humans do. Studies have shown that plants benefit from light wavelengths between 400 to 700 nanometers. Visible light on the other hand includes more wavelengths from 380nm to 740nm. When measuring photosynthetic light those extra wavelengths above 700nm and below 400nm are excluded.

PAR is measured using a specially calibrated sensor which measures quantum flux. Quantum flux is the amount of photosynthetic light hitting the sensor and is displayed in UMOLs/ms. Reading a PAR meters screen will display the total amount photosynthetic energy and can be interchangeably called PAR (photosynthetic active radiation), or PPFD (photosynthetic photo flux density). Both terms means the same thing relative to reading PAR meters.

There is a third measure which can be confusing when comparing a grow lights energy output. Many manufacturers will advertise a term called PPF. PPF (photosynthetic photon flux) is a laboratory measurement. It has very little to do with the amount of PAR or PPFD that a PAR meter will read. Higher PPF numbers do equal higher amounts of potential light output but it can also be misleading based on the lights total shape and size.

It is best to focus on PAR/PPFD because that is the amount of valuable light the plants are receiving.

We know from experience how much light should be provided to various plant types to maximize their growth. These light levels vary based on the plants age and sensitivity to light.

Cannabis for example has several life stages. The seedlings/clones stage when plants are delicate and sensitive to high PPFD levels, vegetative stage when the plants are fully rooted and building size and the reproductive or flower phase when the plants mature and finish their growth then die.

Generally speaking here are the correct light levels for each stage:

  • Seedlings or clones which are newly sprouted or planted: 100 umols/ms PPFD +/- 20
  • Rooted clones/young veg plants: 250 umols/ms PPFD +/- 50
  • Vigorous veg plants: 350 umols/ms PPFD +/- 50
  • Reproductive/flowering plants (not using supplemental CO2): 750 umols/ms PPFD +/- 100
  • Reproductive/flowering plants (supplemental CO2 of 1200ppm+): 1000 umols/ms +/1 100

These numbers are guidelines and not to be considered the only factor when evaluating plant health relative to light levels in your grow space. As a side note, PPFD decreases by about 50% over distance. So reading PAR/PPFD at 24" from your light will decrease to about half if you move the meter 48" away. Because PAR meters use quantum light measurement the inverse square law does not apply.

A growers experienced eye is an important addition to the mix. Plant health depends on hundreds of potential variables. But we do know from experience that when the inner most sets of new leaves are pointing directly up towards the light that the plant is happy with the level of light it is receiving. Drooping, wilted, yellowing or veining are signs of stress which may or may not be from the light being provided.

One thing to note about PAR levels is that spectrum is not being measured or considered. And spectrum does effect plant structure, growth and potency.

PAR meters will read the total amount of light regardless of the color of light being produced. So one way of looking at that is if you had solid orange diodes the PAR meter would be displaying the total amount of energy in just that range of color. Narrow spectrum Blue/Red diode mixes, sometimes called “burple” also display the PAR/PPFD energy total. And with full spectrum LEDs which produce a lot of bright white visible light, the PAR meter is reading the sum total of all of the photosynthetic light being produced.

In all cases the meter is cutting off light wavelengths below 400nm (ultraviolet) and above 700nm (infrared). Different instruments are required to read those wavelengths or an extended range PPF quantum sensor can be used. The light levels above would not apply to the extended range and would be higher.

PAR meters are an important tool for any grower. HID lights like HPS and MH have short bulb lives. The amount of PPFD will decline over time based on the number of hours the light has been operating. The light may appear bright, and it might even read high on a LUX meter but the PAR output is steadily declining.

Using a well made PAR meter which can read full spectrum PPFD is a tool which will pay off over time with healthy plants through each phase of growth.


That is so cool :sunglasses: u showed me that I was watching a YouTube video on it yesterday but this is better have it in words u gd man I’m patiently waiting bro as much time an money :dollar: I’ve been spending on this that’s no biggie :+1:t2::dash::seedling:

Getting closer to flush time!


Nice!!! That’s my grow buddy!!! :+1: :wink: :+1:




The short answer is ‘No’ not out-of -the box . To use the MQ-100 for LEDs , you will need to apply spectral corrections using the following link as a guide : How to Correct for Spectral Errors of Popular Light Sources (apogeeinstruments.com). The reason for this is that the MQ-100 operates with Apogee Instrument’s original quantum sensor. The original quantum sensor uses a less expensive optical detector which measures broadband spectrum lights - HPS, T5 , specifically .

If you want to measure sunlight, or just non-LED electric lighting, then the MQ-100s /MQ-200s are a less expensive alternative .


The ideal solution is the MQ-500 PAR meter

I know these meter’s are not cheap (and not needed 100%) but it’s a great tool to dial in your lights… That being said if your talking about spending this kind of money the Pulse Pro maybe a better buy because the software that comes with it supports Cannabis growing looks really cool (it’s the reason I ordered it)… It’s more than just a Par meter… Mine is on route to me now should have any day now… If your not in a rush I can review it and let you know if I feel it’s better than the Mq-500


Beautiful :+1:t2::dash::seedling:


That’s all I needed to hear :ear: ain’t trying to make my job harder I’m gonna go with the 500 plus ur right I need accurate readings for what I’m trying to do :+1:t2::dash::seedling:


But remember the pulse pro maybe a better option for the same money. I just can’t really confirm until I play with mind.

And I’m sure there is other options also but I can only tell you from my experience


Choppo you gonna be good and ready in a minute!!!
Is that a 3 x 3 you rocking? :eyes::seedling:


That’s gd enough for me :+1:t2::dash::seedling:
