The Physicist's Indoor Soil Vanilla Frosting

[The Physicist]

What makes you think too much light? I’m running 64W of blurple/full spectrum about 10 inches above right now in their own tent.

also why the bloom formula not a veg? They are pretty yellow

 

[Pennywise]

Young clones only need a small amount of nitrogen but use more Potassium and Phosphorus for building roots.

 

[The Physicist]

Wow okay, so I read into what you said @Pennywise and indeed, Nitrogen can inhibit root growth and fight the rooting hormones. Thats fascinating. Learn something new everyday! Recommended levels are 1-3-3 apparently. Thanks as always PW for the information!!

 

[Pennywise]

It doesn’t take much at all at that stage.

 

[The Physicist]

I assumed the yellowing would make nitrogen required to counter that.. making assumptions is always bad science. That was dumb on my part. I guess we will see what happens, I’ll do a bloom nutes ultra mild run on it

 

[BedroomFarmer]

I say possibly too much light because of the yellowing. They are trying to grow instead of root and are yellowing because they are putting energy into growth. I'd maybe try raising the light a little higher and see if that makes things better but up to you.

 

[The Physicist]

I read up a bit and I thinking im giving them too much light and thats forcing the intense yellowing along with the nutes lacking. Going tk back the lights off a bit to 24”

 

[BedroomFarmer]

Yup. Raise it up should help, all you need really is ambient light. I'll be using an 11watter for my 14 site cloner, They need very minimal lighting to root. never had an issue with small CFL but my veg lights marketed as working well with clones killed some killer strains.

 

[The Physicist]

I backed them up to 30” above and switched to 6/2 lighting rather than 24 hours straight. Definitely interesting how they behave. Down the rabbit hole i go
Thanks rich and penny for information! Much appreciated!

 

[BedroomFarmer]

6/2? I run 24 no issues just low watts

 

[The Physicist]

I veg 6/2, it gives younger plants a chance to rest and process the energy they stored. Young plants get energy saturated quickly so light cycling gives them more time to take in light, process it, and take in more, within 24 hours than 18/6.

 

[Pennywise]

I run cuttings at 18/6 but 20/4 will work well also.

 

[BedroomFarmer]

Never heard of 6/2 before, I've run 24, 18, 16, and GLR but dont think ive ever noticed much of a difference. I just run 24 out of laziness but if I wanted to set up a timer, I'd run GLR.

 

[The Physicist]

What is GLR? I like 6/2 so far, all the plants have really taken off at this point except that Gorilla Goo which never had roots but now is yellowing some leaves like its trying

I’m in

 

[The Physicist]

Welcome aboard! I’ll be starting the perpetual journal tomorrow. I am making some final adjustments due to the coming summer heat and the fact it already hit 90+ outside today...

I’ll be sure to sub up on that!

Nebula Haze completed her 300 HLG QB vs 4000k Hortilux Bulb (Vertical Alignment) and results are below:

Note: shes admits that no defoliating was done and therefore the LEC lower buds were mostly thrown into trim and that reduced the weight, which also in turn makes smaller buds and lower THC.

As expected LEC has more terps and more flavors due to the broader spectrum

 

[Pennywise]

Need to run that one a few times I think.

 

[The Physicist]

Indeed, there are a lot of missing variables that can’t be taken on first pass. CMH can easily pull a pound in the same 2x4 space and she also did that grow. But she did it lollipopping and defoliating
