Different medium

Hello, I’d like an opinion on the medium I’d like to use.
I’ll grow autopot, and I know a 70/30 Perlite it’s recommended. Unfortunately, before i knew that, I bought 2 50L bags of 60/40 Coco and pebbles from Growplan. I emails Growplan and asked if i could still use the 60/40 and they recommended to mix it 50/50 with some 70/30 perlite and plus to remove some pebbles. I bought the 70/30 perlite, but I wanted to ask some expert opinions in here about that.
Thank you

You would probably be fine with the stuff you originally purchased. I would suggest thought that a layer of hydroton be placed in the bottom 2 to 3" to prevent waterlogging the media and drowning your roots.

Hi, yes thank you :+1::+1: i have the air base, not the hydro dome thought, (no more money :sweat_smile:). I keep reading everywhere for autopot and bottom feeder 70/30 perlite, so i am a bit anxious.

I run Autopots and have one plant currently. I inadvertently bought coco without perlite and did add some along with the clay balls in the base. I’m running an air dome with the supplied plastic 6 gallon pot but normally use 3 gallon fabric pots with no air. Layering the Hydroton in the bottom will help greatly.

Even with the airbase? I thought they eliminated the need of hydrotone?

I agree with Myfriendis410. The only difference you’ll see in a richer perlite mix is substrate dry out a little faster and less compaction. I can’t think of a single reason that would matter in bottom feed system like an autopot. There are people on drip systems that run 100% perlite just fine. The idea that mixing them to create a 65/35 blend would change something significantly is pretty silly.

Perlite ok. but i bought 2 bags of 60/40 pebbles, while bottom feeder they recommend 70/30 perlite, 60/40 pebbles better for top feeding.
Not sure why is reccomended but if you check Plagron website(i called it Groplan in my other post :roll_eyes::sweat_smile:) they break down each of their medium and give recommendations Plus i mailed them and they said it would be better if i mix the 60/40 pebbles i have with some 70/30 perlite and plus to take out some pebbles, about 50%

Gotcha, I misunderstood and thought it was 60/40 coco perlite.

Hi, I posted a topic about it, but no no one answered yet, if you could kindly take a look at one of my 10-day-old babies who have those light white spots? Any thoughts?

Good day I dont know but I seen a few here. Bugs can do that, a mist humidifier with tap water can put white deposits in vapor, and bad RH% can cause blemish and imperfections. If neither of them present just let it go a few days see what the next set of leaves look like

Hello and thank you.
RH% like humidity? I was always within the media-recommended.
I use tap water but with Oxyplus and Nutriflex for seedling and vegetative stages, which should regulate the PH.
The other babies don’t seem to have those spots.
I’ll keep an eye as you suggested.

I agree, this could be early sign of something, or it could be nothing. The first few leaves on a plant can look a little rough without any issues. If you see it getting worse, spreading, or continue on newer growth hit us back up. But i wouldn’t worry about this right now.
