Whitefire Gelato

[bimblebrains]

yer man,alot of that cookie type stuff is best at 10 /11, and the white fire from rascal had mostly 10 week phenos,damn that was a good hybrid! they only start to bulk around 8 weeks onwards,tend to weigh in more than you expect due to the density of the nug too,a q can look like a henry lol,looking good mate!

A few better pics, theres some orangeing pistils about that couldnt be seen in my itger pics that didnt come out too well. About to go drop the pk13/14 and give some buddy now











Got a bit of foxtailing again on a few of the buds, had alot of it on the braindamage i did under this light aswel. Do you guys reckon this is genetic or something else? The temps never go below 19 or above 27 and humidity is always between 60% and 70% can't do much about that one though as that seems to be what i get for humidity. Got some deficiencies starting to show a aswel i think. Would you all say I've fed a bit too high and thats caused the foxtailing and smaller buds? It's f ing stinking well though mind and praying too which is something i don't usually manage to achieve

i've found that different led panels with in turn their different light spectrums have a dramatic effect on the morphology of the flowers,ive got 3 different brands and all give a change in the shape to the flowers,some more foxtaily,some more round/conish,some more elongated..infact ive got 2 of the same light bought a year apart and they are very different spectrums,even to the naked eye,you can see one is more yellowish,one is more white..they are mars hydro's...so yer same cut,different panel,different shaped flower...ive even got my fave lights for the different cuts its that apparant in the final product...so maybe its the light causing the foxtailing mate

I was beginning to think that, this ones an ish4r and i dont get it with my ish 150 panels. @Invisible Sun Could it be because one r strip is 3k whites and the other three are 3.5k whites?

Foxtailing is a sign of stress , it could be light stress but that's from too much light not from the spectrum.

Spectrum doesn't cause stress, it's not possible , however putting your light too close or under to higher par levels or too much heat could certainly cause foxtailing, but that would be the same for any light including Hps

Won't be the light mate. You got enough airflow?

The extraction is running between 152 and 191m3/h in a 0.75x0.75x2.0 tent, you reckon i need to turn it up? To be honest I'm a bit crap at working out where the light needs to be and at what power so I've just been hsing an app to measure dli which is at 35 to 40 depending on where you measure it

35-40 DLI is on the money. ~170m3/h should be plenty enough too. Do you have enough airflow around the plants? If that's all good too I'm going to say maybe genetics. The plants look like they're still happy. No heat damage on the leaves other than a small amount of curling but that could happen naturally towards the later part of flower. It could be salt stress too but normally you'd see more than just flossing. That's what makes me think it could be an airflow issue as lack of co2 would cause them to slow down and ready off early.

Here is a link to info on DLI along with PAR , PPFD and the rest, iv pasted the article below too

https://invisiblesunled.co.uk/pages/par ... fd-and-dli


PAR is a measurement of Photo-synthetically Active Radiation within the 400nm-700nm range, this is the range of light plants use to photosynthesize. Plants utilise this range of light, the light reacts with Chlorophyll a and b and converts light into energy to grow and thrive.

Photosynthetic Photon Flux Density is measured to determine the amount of micromoles per meter per second µmol/m²/s

Using this figure and some further information we can determine information like par maps and DLI



PPF - (Photsynthetic photon flux) is the amount of light which is in the range of 400nm -700nm that is being produced by a lighting source per second. measured in the umol / second. We use this figure and the power of the light to determine the Umol/J rating. You need an advanced spectrometer called and integral sphere to measure PPF, the light source is fixed into place in a perfect sphere, sealed and tested, the reflection from inside the sphere gives a accurate reading of the photosynthetic photon flux. (ppf)

PPFD - (Photo synthetic photon flux density) PPFD is a measurement of how many photo synthetically active photons reach your canopy. PPFD is important to understand so that you are giving the right amount of light to your plants. It is measure in μmol/s.m². Between 700 - 900 μmol/s.m² is the ideal amount of light for crops which require high light intensity such as flowering crops.

YPF - (Yield Photon Flux) is measurement where photons are weighted in the 360nm-760nm range, it goes deeper than PAR by extrapolating the photons to the plant sensitivity curve per crop. If you have an exact spectrum produced by your grow light you can alter the umol / second values by adding additional colors such as 450nm, 660nm or even 730nm

DLI - (Daily Light Integral) This is the amount of light which a plant can receive and process in a day, it is a combined total of the the amount of photons (umol/s) which reach the plant in a day. The total number of umol is measured as a mole.( mol/d.m² )

Utilizing DLI can be beneficial in making sure your plants get the right amount of light each day, working out exactly what ppfd you need at canopy level will give you the information you need to determine what your daily DLI is.

Using the calculation

PPFD x Hours of light x 60 x 60 / 1000,000

For example for a DLI for light intense flowering crop you should be aiming for the region of a DLI of 40. Using the calculation above we can determine the DLI.

Lets say we have a ppfd measurement off 950 umol/m²/s

950 x 12 hours x 60 minutes x 60 seconds / 1000,000 = DLI 41.04

So you can see by the calculation above that being in the area of 900-950 is going to be the perfect par for flowering crops.

Another example would be for vegetative growth stages, in this stage a lower DLI is required of around 15 -20 If we start with a PPFD of 400 umol/s.m².

400 x 16 hours x 60 minutes x 60 seconds / 1000,000 = DLI 23.04

By using DLI it give you an effective way to measure the exact amount of light your plants will receive daily.

As a guide, Flowering Crops require 20-40 mol/m²/d and vegetative stage required 15- 20 mol/m²/d

You could be onto something with that actually @seymore_budz. The tent is inside what you could effectively class as an old immersion tank type of cupboard with only passive intake for the tent provided by whatever it can drag through the seems and zips (budbox pro without the passive vents open) and what you could class as a door stays shut. But i dont get it in the other tent which is in the same place. The only other difference is the light and the genetics, but maybe i do need a bit more flow come to think of it
