I got stoned and wrote a book. I love this subject. I feel that the organic community has fallen victim to the "stuff" mentality in the cannabis industry. I strive to use the absolute least amount of stuff as I can. I also strive to keep my grow has hands off as possible. Clover/living mulch/cover crops has completely replaced my need for the following: compost teas, sst's, top dressing, worm bins, secondary composting, and hay/straw.
Plants compete for nutrients in the soil with other plants. Why we pull weeds around other plants, they consume the nutrients and water that are supposed to go to the plants I want.
Maybe some hippy bro science organic shit but I can't see any benefit personally to any other plants in the same root zone as the plants I wanna grow.
You are absolutely correct. In small pots (anything under 15g) I don't recommend using cover crop or living mulch due to competition of the water supply. With clover im not worried about nutrients so much as just moisture in general. Not saying it cant be done (H.A.F lol) but it does require a much larger time investment monitoring the moisture levels.
Actually for your set up I'd recommend putting B/White plastic over the tops of those pots. You will literally see a increase in moisture retention and a fuller root ball as you wont be developing that crust on the top as the water evaporates out the pot and a little reflective light under the canopy. Not a big deal either way.
I read this whole study on helping people in areas with infertile dry land. They are growing plants in pots. Covering the pots with white plastic sheeting helped retain water and reduce heat on the root ball. It turned this whole starving community around. Amazing stuff. I think it was in those condition that they saw a 30% increase in water retention. And when you're hauling that water from the river 3 miles away by hand... Save every drop. Since your under HPS with that radiant heat beating down on the pots I figured I'd toss the idea out there. Might save you 2 or 3 watering in a cycle? (im such a cheap bastard)
I reuse all my soil, the older it gets the better the ph stability, I do not have the time to ammend soils for compost nutrients with the lights I use.
I have to use a synthetic nutrient. The pots are to small to sustain the size of the space and demand seeds puts on the plants in week 6+
I personally prefer compost beds opposed to pots. It's what all my outdoor vegetables go in. I keep a huge outdoor garden on my property.
I am so stoked to read this. NICE. Most people would toss it with synthetics. Glad you know better! In small pots this can be challenging. Its much easier to dump small pots into a bigger bin for cooking time. Ive set up a couple people using 2-3 gallon plastic pots. Have 2 batches of soil. One in use, one cooking. Once harvest, dump used soil into giant pot, amend and let set for 2-3 months while your next round is growing. If you are up for looking at a feed that's not a synthetic, check out Eden BlueGold Fusion flower or Organics Alive V-PK. I have several of my FFOF growers that have got off the 3 bottle and onto either of those with awesome results in 3-10 gallon pots.
Stoner Ramblings incoming.
Thats what too many people are missing from a living soil. It needs time to rest and recharge itself. It needs time to eat. THAT is the point of growing clover as a "living mulch". Ever seen a pot with out any mulch on it or some sort of cover? It gets all hard and crusty and shit. And give it enough time its dry 2-4 inches down. The clovers roots only go down a few inches. So you can either have that 2-3 inches dry,
or you can have a very fine root mass growing in it. This root mass is going to make a giant rhizosphere on the top layer. Its nice, moist, and almost spongy.
Now add that we mow this clover often. Now we got leaf littler. Its breaking down. Feeder roots are growing up into that rhizosphere. Bacteria and fungi population explode, nematodes explode, soil mites go up, (suddenly you have no gnats lol) break down is faster, worms move closer to surface because it stays moist and are eating the mowed clover. Soil biology is now PUMPING. That, in my very humble opinion, is Living soil.
And what all are we actually doing? In a bed or the recycle bin, mowing clover with some 14" grass sheers, dumping a small scoop of dry amendments over the clover a couple times a year, and hand watering in some micro nutrients. General watering is set up to water only 5% water to soil volume. So no run off. Its some really lazy shit. LOL You will notice that no shit teas were made, no seeds were sprouted and ground up. I didn't dump 5 lbs of worm casting and 3 cups of (laundry list of amendments) per plant and shit. I mowed some clover. took me 3 min per 4x4 bed twice a week.
This is kinda stepping into that area where we have to be careful with our wording. Organics and Living soil are similar but done differently. Same with cover crop and living mulch. They are 2 different systems, 2 different seeds/blends and several different purposes.
@TreeFarmerCharlie nailed it when he said that it was used for ground cover, moisture retention and preventing compaction. That's cover crop. So now that we know that living mulch is just a giant salad of greens that were mowing like twice a week to feed the soil, lets talk cover crop a little.
Cover crops can be used a couple of different ways but were going to keep it in the realm of what we're doing.
@Heisenbeans I'm going to apply it to your set up as an example.
So were in 2-3 gallon pots. Dumping in a bin and rotating soil. Your on your like 3rd or 4th cycle and you notice that it feels like the soil isnt as fluffy as it once was. So chop up the root balls really good, get everything nice and moist. Then you would seed in a no till cover crop blend. Now we're looking for plants that that got some hardy roots that will burrow down in that soil. Clovers,
Fenugreek, Vetch, Flax, Cowpeas, Buckwheat, Forage Peas, Millet, Lentils are all good seed to use in a cover crop mix.
Were going to let it grow this nice full green top and let them roots get all deep into the soil breaking it up. Then were going to cover it with plastic, killing it all, and let it set till we're ready to swap soils again. If you are doing this in batches now you got 30-60 days of that soil just sitting there. Water some microbs into it and maintain the moisture. You will be amazed at how fluffy your soil is 30 days later. Letting it break down the cover crop, applying the Living mulch, and you got a pot full of nutrients that you can grow plants in again. Be sure to then seed in a clover only living mulch cover. Keep it moist, and chopping clover and you will build an amazing living soil in a few months.
I cant really take credit for any of this just so we are clear. Everything here I learned from soil food web school by Dr Elaine Ingham and a few soil biology and regeneration class I took online at MIT.
