Trying a new form of bottle-tech humidity dome. The closure zip lock is blue, so I’m also interested in seeing any potential blue light effects on their growth.

What are your latest tricks?

Interesting setup! I’m pretty sure the blue plastic will actually absorb/block blue light. It won’t increase it.

[Culver-Creek]

I am going way back in science class but I believe you are correct. If you are seeing a color the material is reflecting that light back out of the full spectrum. if it is blue color it is absorbing (or allowing through) the rest of the spectrum and reflecting back the blue (or some portion of it).

[calikush]

Yeah something like that that’s what I thought, so it might mean they would stretch..would be interesting if he can get some translucent red and see the effect haha

[Culver-Creek]

I’ll be watching also

[calikush]

Like poor man’s spectrum tuning for veg 😂 which I’m all for!

Exactly this. Those sprouts are 3″ at Day 3 end.

I use the same trick with my homemade aerocloner. Zip loc bags over each cutting. I mist the bags everyday and get crazy roots. I have used a couple different brands including ones with a slight blue tint. Didn’t see a difference. Lately I’m just using the ac infinity humidity dome combo.

Nice, I used to use baggies over solo cups if I only wanted a few cuttings. I would blow into each one every day for CO₂. Seemed to work great for me, good advice.

There is zero benefit to adding a dome to any aero cloner, you are more likely stalling the rooting process. The whole magic concept of aero cloners is to induce uptake and then leaf transpiration, negating any need for humidity, the of dangers humidity outweigh any benefits with this method.

Domes on seedlings can lead to rot and dampening off. This is a clone thing where the humidity is needed for the root development. A seedling has a root, domes are not helping this.

[green-giggles]

Yes , I have discovered this.ugh..

Seedlings vs clones need different care

[calikush]

He’s not using the domes though he just has a loosely fitted plastic bag over the top

[battlemorph]

This.

The bag is standing up on its own because of the tensegrity created by the bottle-tech corners. I breathe into it a few times a day to add vapour containing nitrogen and CO2. There’s a small temp/RH meter between the sprouts that holds the bag open (by tension) and approx. 4-5mm of gap at one end. Currently 78%RH and 25.1C.

[Thickems]

When leaves grab water from humid air they are not using root development. Root sits water logged and rots. Each breath in that bag is more moisture. You are covering it but trying to introduce air? Let it breathe, let it develop a root and grow.

[Thickems]

Not sure what nitrogen is doing, mine like oxygen. And high co2 at early stage isnt ideal. Low co2 so large and more stomata are formed, utilize them with high co2 in flower.

[battlemorph]

I figure they are getting plenty of air in the root zone due to the nature of the SmartG12 system. I’l only leave them in it until the roots have struck sufficiently robustly to allow transplant to a final 10 gal pot.

[Thickems]

Its not about the root. Its the leaf and you are restricting transpiration. Not allowing water to pass through and out stomata. This will affect the root development. You are slowing your root growth by sufficating your leaves. Its science and how the plant works.

[battlemorph]

OK, thanks. I’ve uncovered them now, anyway.

A cover is a cover. You are creating a microclimate on a budget.
