However , espouse our tips below for the best resolution potential , including how to rehydrate coco coir . We wish to make our seedling land in a charge plate tote bag , which makes it easy to mix and then neatly hive away to employ later .

Pre-Moistening

Before combine all the element , it ’s best to bust up and dampen the peat moss or coco coir slightly . Both peat moss and coco coir arehydrophobicwhen they ’re ironic , stand for they naturally force back water . So it ’s always a good idea to pre - dampen your seedling mix before use – include before fillingseed embark on traysor sowing seminal fluid . Otherwise you ’ll have a really hard time water your semen .

The wet also help toreduce dustfrom the peat , coco and perlite – none of which you want to inhale , and also makes a quite a little !

Slowly lend just enough weewee toslightly dampenthe medium , NOT make it squashy . If it gets too besotted , peat and coco tend to get clumpy , and it will be more heavy and hard to mix evenly with the other element .

Three five gallon buckets are aligned in a triangle pattern, one if partially full of perlite, one is partially full of peat moss, and the third is partially full of worm castings. A grey tabby cat sits next to the buckets.

How to Rehydrate Coco Coir

To rehydrate coco coir , bestow the condense brick to a large tubful or bucket and total a small amount of water at first . ( anticipate to use about 3 to 4 dry quart of water for a1.5 - pounding brick of coco coir . ) Let it sit for15 to 20 minutes , see how much absorbs , and then slow tote up more water until it easily breaks apart and fluff up . Remember , you’re able to always total more – but it ’s concentrated to take aside excess wet if you exaggerate it !

At the jeopardy of sounding like a broken record , the best seed starting mix is destitute of large glob . Just one clump in the improper place could smother a seed or prevent its roots from arise with ease ! Peat moss and homemade compost are especially prostrate to having a lot of lump and clod .

If call for , you could improve the texture of your DIY seed startle intermixture either byscreeningthe ingredient prior to mix , or block out the finished mix afterwards .

We use a DIY compost screen that we made to harvest and sieve worm cast from our worm bin . It ’s simply 1/2″ hardware material attached to a wood frame with a catchment holdall placed below . Put the contents on top , move it around to strain and work it through the screen , and then hit or break up any large clumps left on top .

A large tote contains peat moss, perlite, and worm castings, each lined up in a row, taking up their own portion of the inside of the tote. Two cats check on the mix from behind the tote.

That’s all folks!
