Extended season starting trees indoors

[Arlithrien]

Hi.
About 6000 seeds.I guess fwschumacher have fresh seed(why they actually run out of supply).
They sprout with no pretreatment.
Never tried without.Kelp has gibberellins which re responsible for first chemical reactions in embryonic germination of the seed.Fulvic acid is a low molecular weight humic substance that will penetrate cell membranes fairly easily( if not a few hours in plant leaf cells).
I personally believe the seed membranes do open in the seems of fresh seed to let the kelp penetrate in a 24 hour soak.
Every time I use it I get very good germination rates.The black pine actually sprout in 4 days!!

What about maple seeds, do they still need a cold pretreatment?

zelkova aeroponics


these are getting bunch of roots.They eventually start getting feathery side roots going.

Coreana Hornbeam Fun

I have lots of these.I want to tru and keep every last one.
Potted up 27 for now in Rootpouch.That will give these dense radial root branching that can easily be trimmed upon removal of the pouch.
I just trimmed the taproots only very slightly and will feed extra mono ammonium phosphate/low nitrogen for next 3 weeks for big roots first!!
1000ppm co2,so these should grow very fast.
I added the grodan chunks for moisture retention because coreana hornbeams are very thirsty plants when they get growing and do not handle drying out that good at all.Like terminals will shrivel very quickly.About 50/50 with grade #2 perlite.
I love these trees.

Just an update to the little jbp’s I got from you like a month ago I top dressed with some sulfur to keep the ph down, and also mixed in some aluminum sulfate in the tea bags with light organic fertilizer. They seem well so far! The drip system waters them for 1 minute every 6 hours.

zelkovas @4 weeks aeroponic cloner

These get better and better.I have had faster results with regular prpogation domes,but this is far easier and way higer rootsfor a healthy start! And no real humidity shock and dessicationn of foliage.
Looks like 100% success all in varying stages.

 

[cmeg1]

transplanted aeroponic zelkovas’

potted up 6 of these.The rest in the cloner should all eventually root.
These get very dense side rooting which is good.
I will give less water spraying the leaves as there is a bit of fungus or mold,but I will spray with some copper or something.
Roots are choppy looking,but after a season in the root pouch they will transplant nicely and be trimmed.

The new grow room setup (double tent) sealed.

The main challenge with co2 enrichment is how to controle humidity without exhausting your enriched air to bring down temperature or RH.
You end up wasting all the co2!

I have gotten rid of the very large 8x4 tent and replaced with two small tents, added a floor air conditioner and also a seperate dehumidifier in the room itself.
Instead of venting humidity from tent to the room,I intake air from the room into the tent with a fan blowing into a 4” duct and the fan is controled to turn on when humidity goes over 60% RH.
This is done by plugging into the multi controlers I use.The room humidity and temp is dryer and cooler and blows in and does not exhaust co2 out
Too high humidity is very bad as plants will close stomata,overheat and not transpire and get deficiencies.......co2 will be useless.
About 40-60% is ideal.Vegetative at around 55-65% is ideal for me.Especially in higher heat co2 environment.
I am currently tweaking room temperature of the AC ,so the tents will warm a bit more to around 80-84f which is ideal in co2.Otherwise 75-80f is good for non co2enrichment.
I have found co2 enriched environments are best slightly above 80f with 85f being max ,ideally.

Co2 is excellent,but everything needs to be dialed in or it is wasted.

This setup is working great.Took me two weeks to get it dialed in!!
Now a 10lb tank @$23 a tank will last at least a couple months at 1000 ppm
The 40 lb tanks are way better being only $27.....go figure......they will last very long.

Has your house ever been raided? Lol.. My JBPs are still growing strong! When's the next sale?

No raid...alarm system anyway.
Next sale about a month or two.
Pines be ready 3-6 weeks and am sewing more today.
Koho’s we’ll see.slow at the start,but pumping heavy with co2 and buildbg roots first,so when I up the nitrogen in another week they will grow fairly strongly.Excited to see how these do with the kelp budding and branching right at the start like this.

You make my propagation attempts look weak

I was thinking the EXACT same thing!

 

[cmeg1]

I was thinking the EXACT same thing!

Haha...its fairly easy,except my electricity bill grew 75% and the initial startup of supplies is a beast....though will pay for itself

 

[rollwithak]

I wonder if Monterey Cypress seedlings can use this cutting method as well to help with the roots?

 

[cmeg1]

Depends...some cut better than others...my hawthorn are packed with callous,but no roots...i imagine they root eventually

zelkova aeroponics

Potted the remaining Zelkova this morning.If I had the patience,would of had 100% success rate.I settled for about 75% and tossed the rest then cleaned the cloner.
Roots look great and vigorous.

I have seedlings coming up that when stems are about 3/16” I will ring bark as a seedling air-layer,but then uproot and put into an aeroponic cloner with roots and ringbark below the collar to see how that goes....Roots should push from the ring bark within two weeks and have an easier way to make seedling layers instead of the old, tedious way of watering them every day.Probably just use a liquid rooting hormone in the resevoir like hormex liquid.
Wish me luck!

Here are puctures of aeroponic zelkova cuttings from this morning and also the previous way I have made seedling air-layers in the past with great success.

What are the cubes at the base of the Zekovas?

What are the cubes at the base of the Zekovas?

They are grodan grow cubes or chunks....one size is smaller than the other.....stonewool cubes mixed with perlite...they hold moisture to extend water holding capacity.

Potted a few seedling cuttings
Only been five days since I looked last.Was able to get 8 in pots.
I put many back into the dome.They are just starting to root and really nicely too!

forgive me but i realize this post is 20 pages long and i may have missed it. What medium are you using to put cuttings in? Straight perlite? Or is there sphagnum in there as well?

Thanks

To root cuttings I use #2 perlite with 50% orchid spahgnum into top 1.5 inches mixed in

Coreana Hornbeam & Jbp seedling cuttings

The korean Hornbeams are done the 3 week root starting phase and I bumped up the NPK.Looking like they will be strong and stocky since the roots are bulked up a bit first...definately worth the first 3 weeks...also apparently the ammoniacle nitrogen from the mono ammonium phosphate is supposedly excellent for seedlings at the very start...something about performing reactions with amino acids directly in the roots or something.
Can see in the close-ups that I have side buds already! They already had three foliar feeds of kelp and it is already supressing auxin and initiating premature lateral budding....this should be cool!

The Jbp seedling cuttings are just a couple weeks or so from sale and I have more seeds germinating now.

Also excited to be preparing many deciduous seedlings for experiments in making aeroponic seedling air-layers.I will uproot the seedlings at about 3/16” diameter and then make a ringbark and put i to aeroponic clo er with ringbark and roots below the collar in the resevoir to see how rooting goes at the air-layer.Should be cool.
Will try zelkova and coreana hornbeams.....they are getting total motherplant preperations to root very easily.
