If you have a oxygen problem. I heard you can use hydrogen peroxide in your water. If so how much. My soil feels really compacted. I just started my 12/ 12. My soil has perlite in it but probley not enough.
stick a fork in it, actually do it several times. all around the outside edge of the soil. Its kinda like tilling around the plants. Breaks it up a little so the water goes down faster which takes oxygen down with it. VV
I always try to give good advice. Flood and drain will pull oxygen into the plant when the water drains out. welcome to the forum. Always room for experience. VV
this isnt a mj plant but 40% of the jar is filled with 3% h2o2 and 60% water. thats a relatively high dosage but it survived and got rid of the slime that was growing in there.
h2o2 can be used to treat soil, when poured in some types of soil the soil will become very airy and drainable when dried and it will stay like that even after watering for awhile. you would have to do this before you put any plants in the soil though.
h2o2 does alot of things when it decomposes, try experimenting and reading about it.
