This means that it doesn\u2019t contain any sort of nutrients or food for the plant, so your plants will be ready to accept whatever nutrients that you decide to give them.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-2424\" title=\"Growing Cannabis in Coco Coir Slabs - Fattening stage in slabs\" src=\"https:\/\/www.growbarato.net\/blog\/wp-content\/uploads\/2014\/10\/slabs-3.jpg\" alt=\"Growing Cannabis in Coco Coir Slabs\" width=\"382\" height=\"235\" srcset=\"https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2014\/10\/slabs-3.jpg 556w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2014\/10\/slabs-3-300x184.jpg 300w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2014\/10\/slabs-3-270x165.jpg 270w\" sizes=\"auto, (max-width: 382px) 100vw, 382px\" \/>There are growers that say that working with flowerpots and <strong>coco coir substrate<\/strong> is better than growing in slabs, but I disagree. Working with slabs has more advantages than disadvantages, as the slabs give your plants\u2019 roots\u2019 more space to grow compared to flowerpots; slabs offer more space even if you place more than one plant in a slab due to it being <strong>one big slab rather than a tiny separate flowerpot<\/strong>.<\/p>\n<p>Another advantage is that when watering, all you need to do is prepare your fertilizing mix, <strong>stabilize the pH and check the resulting EC levels<\/strong>. Either way, you can forget about watering your plants one by one which saves a lot of time and effort.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-2425\" title=\"Growing Cannabis in Coco Coir Slabs - Final result in slabs\" src=\"https:\/\/www.growbarato.net\/blog\/wp-content\/uploads\/2014\/10\/slabs-4.jpg\" alt=\"Growing Cannabis in Coco Coir Slabs\" width=\"205\" height=\"265\" srcset=\"https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2014\/10\/slabs-4.jpg 569w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2014\/10\/slabs-4-232x300.jpg 232w\" sizes=\"auto, (max-width: 205px) 100vw, 205px\" \/>I advise any grower that\u2019s planning their first coco coir slab grow to pick a top quality water pump, an anti-obstruction filter, <strong>one or two airstones and their corresponding air pump<\/strong> so that the water in your pump is constantly oxygenated. \u00a0You should also get some <a href=\"https:\/\/www.gbthegreenbrand.com\/watering-accessories\/1176-12-outlet-drip-manifold.html\">drip irrigation pipes with 12 outlets<\/a>, which are the key to a successful slab grow.<\/p>\n<p>As well as all of the advantages that we\u2019ve already talked about, you\u2019ll get much more yield, increasing the grams per watt ratio, obtaining more abundant yields of higher quality in around as much time as a hydroponic grow; you don\u2019t have to pay as much attention as with a hydroponic grow but you can get similar results. Of course, <strong>I don\u2019t want to discredit hydroponic growers here, I\u2019m simply stating that it\u2019s an easier method that offers similar results<\/strong>.<\/p>\n<p>Something that you\u2019re going to need to stay on top of is the height of your plants as they grow quire fast in slabs; the best way to control the height of your plants and the weight of the buds is by using a <strong>SCRoG mesh once flowering begins<\/strong>; you\u2019ll manage to keep the height under control and increase the weight of your yield even more.<\/p>\n<div style='text-align:center' class='yasr-auto-insert-visitor'><\/div>","protected":false},"excerpt":{"rendered":"<p>Today we\u2019re going to talk about growing cannabis in coco coir slabs.
