I see people starting them in stratum and perlite. Is that the best way to start? What’s next and when? ## 21 comments ### Kayla commented on 2026-05-21 That is the way I start and it hasn’t failed me yet! I use 50/50 stratum perlite mix. I use a 2oz to go cup in a 3oz cup. Put in a wick for a Jerry rigged self watering setup. Then I cover it with a lid or another 3oz cup. In the beginning, I start with no holes for 100% humidity and over time I add holes to acclimate back to normal humidity as the plant starts to grow. If you don’t have a soldering iron, you should get a cheap one on amazon to help you make these holes. If it’s a brand new corm, I lay on top of the soil and peel off the outer brown shell. If it’s more mature and starting to peak out, I just nuzzle it into the substrate a little bit. I used to completely bury the corm but now I leave exposed because it seems to do better. I hope this helps! 🫶🏼🪴 ![Attachment 1 of 3](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/tLacmmWIRZCgGDxF-8y7PQ.webp?size=large) ![Attachment 2 of 3](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/WqH_hgq7Su6C8lNW9zNuMw.webp?size=large) ![Attachment 3 of 3](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/4a277euzT16mB7D_dbrxng.webp?size=large) #### Dana replied on 2026-05-22 Very helpful. Where do you get your cups? Is there a brand of stratum you like? I need to get everything from Amazon cause I have a gift card for Mother’s Day. My kids wanted to make sure I got plant stuff. I see you have a little green house. Do you have recommendations? And do you put a grow light on it and the humidifier gage? #### Kayla replied on 2026-05-22 Amazon has it all! I get the 2oz ones from when we order out but you can buy those too obviously. Fluval stratum. I use this display case for figurines as a greenhouse. I had to use my soldering iron to melt holes to get the grow lights in there with the ones I’m using. I like barina or sansi grow lights. Lots of options of the type depending on your setup. I also have a heat mat under both of the mini greenhouses with a hygrometer inside. You do want to open it up to let them have fresh air once in a while. Added pics of everything I used for this (except the perlite - I think I have miracle grow brand but anything would work). And another pic of the complete setup. Happy to answer any more questions or help out! I love plants and love helping others grow them too! ![Attachment 1 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/K9Yu-CLYS-Kznm2tB-XFxw.webp?size=large) ![Attachment 2 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/BbqPE2ZxSRaBLEGsecd1xw.webp?size=large) ![Attachment 3 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/dG6RETzxRPiWYloKLbzODA.webp?size=large) ![Attachment 4 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/gvADUot-SAOJJiM-7FPljQ.webp?size=large) #### Kayla replied on 2026-05-22 ![Attachment 1 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/Rvh-Za75Q96HykC8rzkfYQ.webp?size=large) ![Attachment 2 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/IEct-ZWbTCeStixP_0MadQ.webp?size=large) ![Attachment 3 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/jo08ILouQlmyYamWjbd8aw.webp?size=large) ![Attachment 4 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/7W1V-zNhR_i3RHvnHbeBtg.webp?size=large) #### Kayla replied on 2026-05-22 ![Attachment 1 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/1c-FkO0qSEmCwBH14lKhsg.webp?size=large) ![Attachment 2 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/v9Z51WJPQXup_AbdZnYzeg.webp?size=large) ![Attachment 3 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/7ry-KXisQ3iJu4qwN4Fkbg.webp?size=large) ![Attachment 4 of 4](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/z4NTz7nYQamXfdNY7fFIyg.webp?size=large) #### Kayla replied on 2026-05-22 The barina strips are held up with magnets. And I used sansi pucks and just laid them on top lol If you want to talk more. Feel free to reply or I can even give you my # if it’s easier 😊 ![Attachment 1 of 1](https://images.getplanta.com/v1/resize/nPE-ta23hyzfm1wkhW7JD_Qz_NLis5vo2H7NCQaKZ0M/fZsDzKZSRSCZMTPSqSMyhg.webp?size=large) ### Dana commented on 2026-05-22 Do you use the same process for propagations that are rooted? I’ve got a Brazil and I think a neon pathos that have great roots and seem ready for the next step. Would you suggest stratum/pearlite and the “green house” until their roots are strong? Or do you just do this process with corms? ### Kayla commented on 2026-05-23 For really small plants or infant props with roots, I leave in here as long as I can until they don’t fit or I need more room. Mostly bc they grow faster than if I took them out. You absolutely can still grow props outside of a greenhouse setup. Just noticed it goes way faster in one. For things like pothos and syngonium that I prop, I use big clear bins with lids. With a grow light, heating pad and computer fan to give some air circulation. No matter what, I always would use stratum/perlite for corms or props. I used to use stratum only but it tends to disintegrate way faster and it gets sludgy. I will start with water for pothos and syngonium cuttings. With pothos nodes only, I’ll throw them in stratum/perlite. Didn’t have good luck with Sphagnum moss. And you can also use the puddle method with corms. Just tried it for the first time. Once I got some roots, I put them in the stratum/perlite setup. #### Dana replied on 2026-05-24 I ordered the little display case, the humidifier reader, heat mat, stratum and grow lights for the case. I need to get the little cups and rope. Got one of my dream plants today. Rattlesnake plant!! ![Attachment 1 of 1](https://images.getplanta.com/v1/resize/L0x7h3JVvda2_LUsnEVA1XKQl0rwR5sfskNeY-4LmPs/lI5Fx5HwSdi6NN2P3XyWkg.webp?size=large) #### Dana replied on 2026-05-24 Question about the computer fan. Did you have to drill holes to get it in there? How does it handle the humidity? #### Kayla replied on 2026-05-25 If you have a sweatshirt with a drawstring you don’t use or a shoelace, that works too! I try to find anything around the house that I can make work. For instance, to go cups from Starbucks or any fast food are great to have a mini individual greenhouse lol. I love the way rattlesnakes look but I killed my first calathea and have a little PTSD from it 😝. I was a beginner when I got one so I’m sure i wouldn’t kill it now. They are just finicky #### Kayla replied on 2026-05-25 So for the fan, I used double sided tape in my bin. I don’t have one in the display case. It does get rusty bc i do mist inside the bin or case. Everyone i follow on youtube tends to use them. I think if I didn’t mist it wouldn’t be so beat up. Otherwise it does the job! #### Dana replied on 2026-05-26 How do you plug it in when it’s inside the case? Did you drill a hole for the cord? I also have my grow lights laying on top of the case. Will it get too hot? _1 more reply in the app_ ### Kayla commented on 2026-05-26 For my bin, I could put the cord over the side and the lid would close. For the display case, I used my soldering iron to make a hold for the lights to be inside. You can seal the hole back with some of the water strip seal (I didn’t do it bc I was lazy). You could also drill a hole but it’s gonna be a few drills to get that cord end through it. I did 2 holes on 1 case and 1 hole on the other and pulled the cords through all of them so just 1 long string through both cases with both lights. And I also have my pucks on top of the case and it hasn’t got too hot yet. It gets warm. Prob should read directions to make sure it’s 💯 safe lol. #### Dana replied on 2026-05-28 I felt the top of the case and it’s not hot at all. There’s no precipitation inside. I’ve got a small prop container next to it that fits on the heat mat and it’s totally humid. I’ll send a picture later. Just got home from work. #### Dana replied on 2026-05-31 Here’s my set up. I’m pretty happy with it. ![Attachment 1 of 1](https://images.getplanta.com/v1/resize/L0x7h3JVvda2_LUsnEVA1XKQl0rwR5sfskNeY-4LmPs/5k5AcgLzSHiVv7OAsNgy9A.webp?size=large) #### Kayla replied on 2026-06-01 It looks amazing! I love it. Please keep me updated on how they do!!! 🤩❤️ #### Dana replied on 2026-06-13 I just got back from visiting my dad in CA for a week and all my corms are sprouting! The ones I put in the little shot glasses actually have leaves starting! So excited! #### Kayla replied on 2026-06-13 Ahhhh that’s awesome. And the nice thing about having them in the case is that you can go away for a week and because of the humidity, they don’t usually use up all their water. I need to see pics!! I’m so excited for you 😍 _1 more reply in the app_ --- _Source: the Planta community (https://getplanta.com). Reading is open to everyone.
