I am growing 1 plant in a 20L pot of soil. There is a layer of rice hulls on the bottom of the pot. Then I added the worm castings. On top of that is the biobizz light mix. I mixed in 4 tablespoons of dolomite lime and 3 of diatomaceous earth. I mixed in some mycorrhizae near the top. I wet the whole pot.
I let the seed soak for 24 hours in a cup of water, then put it in the soil. I could see the seed opening already when I put it in. 2 days later it sprouted.
Looks like we have the same sized tent... good idea to let one plant flourish in there! I'll be growing some mango smile later this year - great genetics! Good luck
@PositiveVibes,Thanks - I learned the hard way. My first two indoor grows, last year, I tried packing four plants in that little tent and it was so crowded in there, I could hardly get the watering can in far enough to water. That was before I learned how to prune 😆
I’m thinking maybe your PH was off . I can’t make out what kind of soil you’re using . I’m grow in coco and my ppm is around 1200 for my mango. Week 10 and not one yellow leaf ! Advanced Nutrients is the way to go !
