How To Repot Seedlings Grown In Rockwool

A step by step guide on how to repot seedlings grown in rockwool, including timing, growing media, and how to reduce the risk damaging plants.
In a previous video I showed how easy it is to sow seeds using rockwool cubes. Rockwool is a mess free way of planting seeds, just pop the seeds into the rockwool, and about 7-14 days later you should have tens of seedlings for replanting. There’s no need to get hands dirty, and sowing is very fast.

finally someone who actually shows how to transplant seedlings from rockwell to soil

[@stevieoneder8091]

I hear some people call it "rockwell". Why?

[@EpiMetricsGF]

Great video. Just what I was looking for!❤

[@richard.hart.]

Taken ages to find this video but it's incredibly helpful. Great simple instructions

[@AllotmentBook]

thank you very much for your comment

[@CarlStreet]

Excellent Video -- Good Sound; Good Camera Angles; Good Lighting; Good Scripting; Good Pacing; practical, useful, informative content -- AND you avoided the "CHEESEY" special effects that plague so many and mark them as inexperienced, ego bound, amateurs. Well Done, Sir!

[@chicksgrowtoo]

Great directions and info, straight to the point!! Thanks!!

[@Mona-fd5kf]

Thank you for sharing, I have tons of this stuff and it would mess free in starting seeds.

[@worrun1505]

Another great video! I've made Gespacho twice using your recipe this year :D

[@AllotmentBook]

Thank you - I really appreciate the feedback!

[@ggesdsdsdsd]

Perfect, thanks!

[@brusselsprout5851]

Thank you

[@satelladeveaux1558]

Still a good clear video except for the compacting of the soil. Thanks.

Where do you purchase the Rockwool Growhouse? Thanks

[@trulucas9917]

Do you know where I can purchase a rockwool grow house?

[@geofflukins8913]

Where did you get the rockwool grow house please

[@Ezzequiel2517]

After you've inserted the seed into the rockwool, should should they be kept in the dark or under light?

[@AllotmentBook]

i keep mine in the light

[@azizhidayat9210]

Izin share kak

[@chrisconnell2147]

did you cut your rockwell round or buy them,

[@AllotmentBook]

I bought them

[@eliotthecaveman]

Would love to know the brand name of that rockwool hydroponic box? :D Pleases

[@AllotmentBook]

It's been a number of years since I made that video... but I think I bought it from a real shop rather than online! Sorry!

[@benhargrave2605]

I just did this to my seedlings and their leaves have curled quickly after 😢 I made the soil quite moist but im wondering if i overwatered it -- could that be why they've curled?

[@AllotmentBook]

This may be a normal reaction to repotting that should settle down after a few days. If the pots drain well after watering then overwatering is unlikely to be a problem (the soil should not be allowed to dry out). Other potential causes are the soil being too dry, or a nutrient deficiency.

[@Intan-bt5lw]

i use this method and my plants looking withered, is that normal?

[@AllotmentBook]

this does not sound normal - withering could be for a number of reasons. When I transplant from the warm propagator to a pot, I like to keep the potted seedlings in a protective area to help them acclimatise to a colder environment (plastic greenhouse, polytunnel, greenhouse etc) - I keep track of the temperature using a thermometer that records min and max temperatures

[@Brandon-xe1yt]

whats the point of using rockwool to transplant them to a pot that small .

[@AllotmentBook]

Using small pots allows many pots to fit on a small windowsill for growing on until they can be moved into my (unheated) polytunnel when the warm weather arrives. If I had a big windowsill (or many!), a conservatory, or other warm light area I would move directly into bigger pots!

[@danielphillips5229]

do you think rockwool is better than coir to start seedlings? seems like rockwool is less mess but might be more expensive in the long run.

[@AllotmentBook]

thank you for your comment. I prefer to start small seeds, like tomatoes and lettuce, in rockwool cubes, and larger seeds by preparing small pots filled with compost made from coco bricks. Rockwool cubes are very fast and easy to use, mess free etc - but are not big enough for some seeds (like squash, cucumber etc.) Compost made from coco bricks is also mess free, but takes me longer to prepare. I find coco really reliable, I think because of the balance between moisture and air.

[@cathyclark8836]

I have always used Grodans Rockwool but I am going to try coco coir and grow dots with recharge. The coco way is a lot cheaper.

[@ziggehed6166]

Scott Malkinson is that you?

[@CasaMetalica]

someone knows the name of this rockwool factory. It is round and not square. Im doing research. In my country we dont have a rockwool for growing..only for roof...

[@cathyclark8836]

I've been growing for several years now and I have never used anything but Grodans Rockwool cubes and mini slabs. China just built a Rockwool plant and they manufacture cheaper products. I tried them once but I had rather buy American made when I can.

[@blacklabel130]

squeezing that much the soil make roots harder to make their way... stop doin this stupid thing

[@OurLucylocket]

I agree terrible video.

[@satelladeveaux1558]

Don't conpact the soil, make hard for the roots.

[@whatzitooyaa1599]

shuut uppp mate no meed to be harsh, at least his voice sounds so hot! not like yours i guess
