Caly Posted May 25, 2020 Share Posted May 25, 2020 Hi All, So I’m starting my grow this weekend and I’m unsure whether to grow in pure coco (pro plus) or get a coco perlite mix? What are the benefits of either and which is the best to use? Thanks 2 Link to comment Share on other sites More sharing options...
golf.007 Posted May 25, 2020 Share Posted May 25, 2020 Pure coco imo is the best and nothing else is needed, adding perlite to the mix is just making less room in the pot for roots and fucks with the cation exchange rate. pure coco ftw 4 Link to comment Share on other sites More sharing options...

seb88 Posted May 25, 2020 Share Posted May 25, 2020 It's not required and you can get great results without. But, I do think growth is a bit faster with some perlite mixed in (im using about 15%). I've played around with and without and think I get slightly better results with, but that difference isn't much, and I've not done a side by side grow so couldn't be certain. It allows more oxygen to the roots but will require more frequent watering to keep it saturated. 2 Link to comment Share on other sites More sharing options...

zen-ken Posted May 25, 2020 Share Posted May 25, 2020 @golf.007 you have probably forgot more than I will ever know about coco lol. im intrigued tho as to why the pure coco. i hate perlite but vermiculite is a winner winner in coco ime....I found it very easy to overwater in pure coco but this was 20 odd years ago Link to comment Share on other sites More sharing options...
HippyHair Posted May 25, 2020 Share Posted May 25, 2020 Only easy to over water if you haven't setup the root system properly. I've never had a problem over watering its why i went coco. Dirt is typical of over watering but treat coco like dirt i do before a root system is developed. 2 Link to comment Share on other sites More sharing options...
joba Posted May 25, 2020 Share Posted May 25, 2020 coco or coco mix is hard to overwater but possible,you saturate the root ball if you not fully rooted and over water,keep that in mind,always best to feel them by weight not just to look especially when they are young if hand watering go plain coco if using drippers go mix but 60/40 mix i would recommend 1 Link to comment Share on other sites More sharing options...
Rufus Brown Posted May 25, 2020 Share Posted May 25, 2020 Only use canna Coco but they were out of stock on my last order so had to grab some bags of ecothrive Coco lite which is a 70/30 Coco to perlite . Will let you know how I get on with it . 1 Link to comment Share on other sites More sharing options...

T0M Posted May 25, 2020 Share Posted May 25, 2020 Dna coco Cork mix I liked definetely noticed better root development. I've used the coco perlite mix aswell and imo plain coco is better. 1 Link to comment Share on other sites More sharing options...

catweazle1 Posted May 25, 2020 Share Posted May 25, 2020 Which do you want: more air, better gas exchange and eliminating overwatering or (supposedly) more roots? As far as cation exchange capacity goes, it is small and for the slight alkalinity just soak in ph5 acid for a day or two. I'm an outlier on this here I think. 2 Link to comment Share on other sites More sharing options...

So if I get a 70/30 this will eliminate over watering completely? 1 Link to comment Share on other sites More sharing options...
