Great video, thank you! I’m very new to hydroponic growing and so I didn’t catch how you treat the water for soaking the rock wool? Do you need to make it a bit acidic, say from 5.5-6.5? If so, what did you use? Thanks again,

[@pandarush.]

I am new to rockwool, therefore I've been watching dozens and dozens of videos. You're the only person that said not to saturate the Rockwool & seed because the seed can drown. Now I see why none of my seeds ever germinated. Thank you!

[@toastiesburned9929]

On the package, mine says if you submerge it only do it for 15 seconds

[@backupintheday9710]

It's a much better idea to grow from cuttings you know are all good from the same mother plant. Then all the plants will grow at exactly the same rate and shape as they are clones.

[@valeriesanchez3074]

Love using the rockwool. My cannabis seeds germinated fine 🙈🙃

[@kunglaomorales5810]

After they sprout do you give nutrients under or spray it??:/

[@toastiesburned9929]

@@kunglaomorales5810 no nutes for 2 weeks is what I've heard, I've also heard keep the ppm under 200 and it won't hurt them. I'm still doing research and planning for my first grow. Wish me luck🤞

[@hogdaddy3768]

Do u like farts?

[@MattyEngland]

@@toastiesburned9929 No nutes for 2 weeks only applies to soil. Rockwool will need nutes from day 1, there are special formulas for seedlings

[@robertthrem3382]

I don't trust the seeds. I soak them with water with some peroxide to add the extra oxygen for 2 days and I will know what part goes down and one part goes up and put it in the Rockwell cube..

[@judithgiannetto1426]

Do these trays need light or can i grow them in my basement till they sprout? THX

[@GMT439]

I find it more reliable to germinate seeds in Jiffy pellets and transfer them into the rockwool cubes. It works fine , no issues at all.

[@AleksandraTheGreat]

Update...my plants are growing slowly and another round of seeds are sprouting... I did loose 5 plants but is ok 😊

[@joshuachen8467]

Hi, may I ask whether I can pluck one seedling out of the rockwool cube after germination. Tks

[@grasthube]

use gloves please. the rockwool leaves a lot of fibers on your hand and possibly face which can sting you.

[@jerimcgee]

It is not fiberglass it don't sting

[@TheGrowGeek]

Thanks Sandy. Hope you subscribe to this channel I making a lot of videos this year . on my home systems. I grow tons of greens and it a super simple and cheap system I use. stay tuned

[@ggesdsdsdsd]

Will tap water do fine? I used it and it looks like the seeds a going to sprout?

[@LucienDubucmrgreenjeans100]

Do you have a video of what you do after growth starts? Those are pretty nice looking heads on either side of your seeded rockwool cubes!

[@RusticRaver]

PH water is real important! in some places water from tap is ph 8 bring that down!

[@Charlie-zj3hw]

I've had stalks that filled the 4 inch net-pot completely .. I was getting a # per plant ..hydro is too much work you're a slave to the grow room

[@andrewdavis6191]

thanks for the great video! liked & subscribed. Can the same rockwool be used throughout the entire grow process?

[@bogwalkerexpress3557]

Thank You for this vid...I suggest a couple things , I got from your vid 1 I will use cotton fiber insulation , I am allergic to fiberglass products 2 I will make a draining tray to fit over the solution for the water mixtures , rather than drain excess into sink drain 3 I will as I watched the abilities of your rockwool cubes.. I will not need the thickness so I will cut my cotton fiber insulation into 1/2 inch depths to start and then soak n drain more of my insulation with your water mix solution and then use pebbles and fiber to hold future growths upright and sturdy :) So many allergies here... and now from your Excellent demo vid , I can visualize for my needs. Thank You Again , now I have a plans too :) Sincerely, Old Sister Boggs :)

[@TheGrowGeek]

BogwalkerExpress good stuff couple things rockwool is not fiberglass or ( spun plastic) its actually rock thats heated to 2500 degrees and spun like candy floss so it should not affect your allergies. and the rock wool is a substrate to support the roots and stem mostly. so 1/2 inch you may have issues with the plants falling over has it gets top heavy? just a couple thing to consider. good luck with your grow :)

[@terrynicholson5214]

BogwalkerExpress have you tried clothes lint from a dryer? Same mateial just wondering how did yours turn out?

[@jerimcgee]

[@Rhonda2580]

If I start my seedlings this way, and then transfer them to net pots with nutrients inside the house until they get a bit larger, do I have to harden off the plants before I move them to my outdoor hydroponic system? We are in So Cal so no worries about cold weather, but it is warmer outside than in the house.

Would you use vermiculite to cover other seed types as well? We are planting green peppers and tomatoes. Thanks!

[@jerimcgee]

Not necessary to use vermiculite at all

[@F4Insight-uq6nt]

Grow a mother plant and root the clones in the rockwool. (Also you can use jiffy pellets to start seeds and transfer them into the rockwool cubes with no problem. Growing crops from seed is a bad idea and will result in a non uniform crop, uneven canopy, different finishing times and feeding schedules. Always grow from proven clones. (Like Professionals do.)

[@VeroKen20]

Thanks! That clears up all the things I've been doing wrong!

[@colleenakaleeannrogers1486]

I ordered some from Amazon, and when I attempted to cut them apart they crumbled in my hand. I returned the remaining cubes because I don't know what that was, but it's certainly nothing like what you are showing here.

When you grow the lettuce with two seeds in one rock wool, do you have to separate them when you put them in a hydroponic tower, or can you have both plants in one basket/pod? Thanks

[@CasaMetalica]

Thanks to post, but I have a question. In this phase you dont fertilize the cubes?

[@SCL111]

Can I leave my rockwool cubes outdoor and uncovered because it's summer? Or should I put it in a mini-green house indoor, next to a window?

[@ChallengeTheNarrative]

I use food packaging deep trays (mushroom trays) for humidifiers. Place one on top of the other and boom gardening hack. Can clip two pegs on to secure.

[@jnorth52]

Great video. Your process is superior to my past attempts with low germination results. As you said, Vermiculite is inexpensive, $10 for 8 quart, but I do not own. Would Perlite or a small shard of rockwool work in it's place? $10 bucks is $10 bucks. Thanks in advance...

[@TheGrowGeek]

Yes as long as it covered and not packed down to hard as the seed will have problems getting through with some plants

[@giminirush77]

hi could you tell me why is my rockwool takes 5hrs to get damp? are there many types of rockwool available out there? thnks

I’m wandering, could u cut out the step of adding vermiculite to cover seeds in germinating, I’ve seen other seed germination just covered with another tray or a dark plastic bag, I’m trying to avoid handling small items bc of my situation. Thanks, Shalom!

[@jerimcgee]

You don't need the vermiculite at all. Just place your seeds in the holes with tweezers

[@manuelsala1631]

After seeds germinate... how many times do you recommend me to water the little plants? or i just keep watering the bottom of rockwool?

[@TheGrowGeek]

Keep adding a little water to the bottom as needed, not too much as the wool will suck up everything you give it and that will drowned your plants.when you see the "tap roots" start coming out of the bottom of the wool, then its time to transfer to the the pots and giving them nutrients. don't forget to subscribe as I am filming more about "From seed to plate" this month. which will give you more insight in to the life cycle.

[@markrich3271]

Your supposed to let them sit in ph adjusted water overnight.

[@pettermath]

what did you call the stuff you present after the seeds? cheers. great video

[@TheGrowGeek]

Its called "Vermiculite" you can get it cheap from most DIY /Home Improvement Stores. It keep the seed moist but allow air which is very important so not to drowned your seeds :)

[@tashasinspirations9029]

I had the same question - so I looked it up. Hope this information helps you out. Here's what I found... Vermiculite added to the garden or vermiculite in potting soil increases water and nutrient retention and aerates the soil, resulting in healthier, more robust plants. ... Use vermiculite alone or mixed with soil or peat for seed germination. This will allow seeds to germinate more rapidly.

[@seyedahmadqolami7360]

[@matthewwood6038]

Wow, thanks for a great video! Just starting out on hydroponic gardening and this explained everything I needed to know!

[@TheGrowGeek]

Yes tap water will work but success will be determined on the chlorine content of your water and the pH levels. check this video of mine for detail on how to do that and prep the water its very easy: Water Preparation - pH stable and chlorine removal before use in my hydroponic system

[@cooller8888]

wrong :D you didn't even pH the water...

[@euroruroweb8537]

I didn't understand what you put on the wool blocks after inserting the seeds inside. Thanks Very interesting tutorial.

[@zane3556]

Euro ruroweb just water. Make sure all water used is de-chlorinated and properly PHed

[@j.d.waymond6355]

The part about the cube being too wet and "drowning" the seeds is confusing: given seeds can germinate in a glass of water.

[@danielphillips5229]

good point, but if you use a paper towel you will be removing it to put into something else once its popped, in a cube you dont remove it so if its too wet the seedling might drown as its left in the cube.

[@mollieahmed3581]

The issue with hydroponics is you need to pay for "plant food" or nutrients and supplements which can be costly.

[@TheGrowGeek]

Actually it cheaper than growing in the ground. you still need to feed those plants plus most of that food is wasted. then there is the insects to contented with, bad weather conditions, too hot, too cold, hydroponics if faster, cheaper and you get more consistent results than rolling the dice with growing out doors

[@Verisetti]

Oh I thought you meant other rock wood didn't work for me the construction kind lol.

[@DROY2004]

I must say as a producer of training videos, yours was very good, you covered the process thoroughly, lighting was good but I have a headsup for future videos, invest in a lapel mic, they are not expensive & it would make your videos Primo by cutting the "bathroom effect" ( echoing, sound fall off, etc ) I know I'm being picky but it's what I'm trained to do, I can't help it. haha -Thnx for the knowledge!

Hey grow geek nice video! I am currently starting seeds as you display it here and i got one question. What if both seeds in one cube start growing into plant? What do i do? Do i pick one out? Or do i let them both grow from one cube? thanks for response

[@TheGrowGeek]

They generally both grow so I wait for 10 day or so and cut of the the weakest. don't pull it out! snip it at the base this way you wont damage the other root system. you can leave them both sometimes I will do that because I will harvest them in 3 or so weeks so the space is not a problem check out my time lapse of the seed I did. these have 7 plants per cube :)

[@spockmcoyissmart961]

TheGrowGeek got that right. You can do everything perfectly outdoors; nature conspires against you and wipes out your efforts in a day or night. sudden hail storm, frost, bugs, animals, etc. airborne blight from contaminated nursery stock..... I grew plants from seed starting in the winter. planted in spring. the big box stores sold plants from a southern nursery that did not decontaminate their planting material and a blight took hold. It was shipped north, and the orange/blue box stores sold the blight infected plants, which when mature spread their disease airborne and wiped out my plant harvest too. Not a good year.......

[@BORAZU1]

If there's no rockwool, what is to substitution

[@TheGrowGeek]

Some people use soil or potting compost to start then wash off the roots and transplant hen to the hydroton, but this is very stressful on the seedlings and you can get some plant loss, the property of rockwool you need it its soft so roots can grown through it , it retains water and air(important so not to drowned the seedlings) and its cheap. I get mine from amazon very cheap : click here: www.amazon.com/gp/product/B0087SJ3U0/ref=as_li_tl?ie=UTF8&camp=211189&creative=373489&creativeASIN=B0087SJ3U0&link_code=as3&tag=thgrge05-20
