Bear Face's Small Batch Hydroponic Grow Low

[ChinaVoodoo]

Agreed. It's kinda new to be looking at purple photos.

I haven't done the math, but the growth you have feels appropriate for how long they've been growing.

Here is the KY17 and the bright leaf

not even close to the same growth rate

this is... about 24 days after germination just showing 3rd and 4th leaf

I planted on March 11, and this was 30 days later.

Tobacco is starting to grow. Goose Creek is the best. For perspective, these pots are 3.15" across.

Samporis, two left rows, and Kasturi, one rift row are doing well.

Nostrano is fine (two right rows). Kasturi one row on left.

TN90LC, two left rows, and KY 17, one right row, aren't doing all that great.

One row of KY17 is good though, left, those were the first to germinate, the others were transplants. And Isleta Pueblo two right rows are doing well. There's also two tomatillo plants in the bigger pots there.

Since I think someone will ask, I sprinkled perlite on the soil, along with watering less, to eliminate the small flies I had. It's mostly worked.

What about temperature?

Mines staying around 60-65

 

[ChinaVoodoo]

I can't say what it was, but I would have been aiming for mid 70s.

Oh well, i added some 4-3-3 nute since im only using vermiculite and will see if that helps. Its suppose to be 1 tablespoon per gallon but i used about a third of that.

I think maybe since its a little colder its just taking longer..... buuuuuut... no idea. Trial and Error i guess!

I think your temps should be about 25 celcius (77f) , 22 minimum at this stage. I realize it may be hard to heat the whole room. With a humidity somewhere around 60+ %rh.
If it was me I would be running about 400 ppm at this stage, are you running 1000ppm already? And going to add more?
Unless I misunderstood, then I think your low temps and maybe high humidity are slowing transpiration and allowing your high ppm water to not burn the plants.
But that being said they seem to be growing very healthy.
Could you post a picture with natural light some time and a bic lighter set in for scale.
Keep in mind I don’t know anything for sure I just thought 400pm was plenty for a little plant.
A seedling heat mat may help get local temps up a bit?

60°F is around the minimum soil temp for seedlings to grow adequately. Your seedlings look ghastly, due to the unnatural color of the photographic lighting (seems you could control that), but seem to be correctly shaped for normal plants. Hard to judge the size.

Nicotiana rustica seeds usually germinate faster, and its seedlings grow more rapidly (and with more abundant trichomes), compared to smoking tobacco (N. tabacum). So, given the relatively low average temp, I suspect they're all doing well.

You could probably heat the water to 78F with a submersible fish tank heater.

 

[deluxestogie]

Of course, with an indoor grow, the growth rate is completely free from the constraints of seasonal considerations. Other than requiring patience, it doesn't matter how fast they grow. With the exception of actually having gravity, your grow is not all that different from the plant experiments on the International Space Station.

In post 77 picture #3 it says in caption above “ec-.17”. Should this read
ec-1.7 ms/cm or ec- 1700 us/cm
I’m just trying to clarify for my own knowledge.

the seedlings are only in vermiculite, the high ppm is for the currently fruiting Carolina reapers in the hydroponic system. i do plan to empty the tank and scrub it down before i add the tobacco to the system. ill then lower the ppm and start small, maybe 400?

yeah thats what it reads ec- 1700 us/cm - i called support from the company making the nutrients and they told me its reading the numbers past the . so 0.17. from what i read you want it between 0.1 and 0.3

 

[2Baccy]

I think 1000 us/cm is equal to 1 ms/cm which would make the guy from the nutrient company wrong. But the nutrient company should know. I believe the decimal belongs after the first digit of your meters reading if converting from us/cm to ms/cm. Just my thoughts but I can’t say anything for sure.

your right im worng.. miss quoting.. its 1.7
