Problem with the soil Biobizz light mix

[freaky99]

Can anyone tell me the exact percentage of perlite in Biobizz Light Mix soil?

I've done a lot of research, but I can't find anywhere the exact percentage of perlite contained in the Biobizz light mix... Some say 10-15%... Others say 30%?

I use Biobizz light potting soil for my auto...

During my last cultivation with this soil, I noticed that the soil remained wet for almost an entire week with only one liter of water in a 20 liter pot at a temperature of 23-24°C and a relative humidity of about 60% and already quite large autoflowering plants (80 to 120 centimeters with many long branches)...

This caused nutrient blockage and pH issues...

I have the same problem when watering young plants... 250 milliliters of water and the soil stays wet for almost a whole week... Sometimes it stays wet for more than a week...

I think I'll add 20% perlite...

How much perlite to add at most?

It's not a problem if I have to water every day and use more fertilizer...

If biobizz isnt coco which it sounds like its not. Sounds like you need to run coco if you wanna water and feed more often.

This doesn’t make sense a plant 80-120cm should drink down a liter in less then a day when my plants are that size they are drinking a lot more. When plants are young it’s not uncommon to go a week without watering even in coco.


If you really want to add perlite it’s all personal preference up to 30% generally. Haven’t heard of many folks adding any to biobizz but I have no experience with it so it’s just hear say

I used BioBizz Light for several grows, adding at least 20% perlite. Just keep in mind, you're diluting the nutrients in the soil by that much, so you'll need to feed earlier and more vs. uncut soil. The only difference I saw vs. coco/perlite was smaller plants, lower yield. I saw no benefit for me in using the soil uncut.

I suggest dilute the Light Mix rather well with perlite and a smaller portion of coco and from there just treat it like coco. The soil will get you through say about 2 weeks, then start feeding reduced dose nutes.

If you want more flow biobizz makes a biobizz HF which has like 20% more perlite in it for increased drainage but the light mix is definitely good enough. I might be thinking of promix soil though so don't quote me. Its hard to keep track of all the different soils used. If you arent getting good drainage or airflow through the soil it could be compacted or packed in the pot too tight? Are you in plastic pots, plastic pots do not dry back nearly as fast as fabric pots. A good rule of thumb if you can do it is to heaft your pots and go by weight, once a pot is half its saturated weight it can be watered again. I usually wait a little longer like 1/3 it's saturated weight.

But it sounds like your plants also may not be transpiring water very effectively either, but that could be a number of problems. Your environment seems fine though so I can't really speculate much.
