I used to just run 100% coco and had no issues. Edited May 30, 2020 by ukbudz Add more 3 Link to comment Share on other sites More sharing options...
H + H2O Posted May 30, 2020 Share Posted May 30, 2020 I use ecothrive coco, but the last time I ordered online I got sent their Coco light 70/30 mix, being too lazy to send it back I used it on half my plants and used my old bag of pure Coco on the other half. I've just chopped the girls last week and there was very little difference between the 2 substrates in the way of yield, the perlite holds less water tho so took slightly less solution. I bought the pure Coco again for this run but had enough of the light mix left to fill 2 pots, the other 7 I filled with neat. I really don't think there's much difference to be honest.

Guest icki Posted May 30, 2020 Share Posted May 30, 2020 (edited) Roots equal fruits, perlite just isn't needed in any regime. Edited May 30, 2020 by icki Link to comment Share on other sites More sharing options...

Adding 30% perlite means less available nutrients for the plant to uptake. Coco doesn't need any help in drainage it runs straight through so there is really no point in adding perlite. Atb That is totally moot when you water everyday or more... that's the point of watering: Feeding. It doesn't run straight through the pot enough not to drown a young plant. Perlite avoids this completely. Pour it all through and forget. Link to comment Share on other sites More sharing options...

So, what about gas exchange in the root zone... doesn't that matter? Is more air there not good? 1 Link to comment Share on other sites More sharing options...

Id say to this ...dont over water then.Perlite is a health hazard possibly thats enough for me. Ive had to sweep up perlite from 2 bags of that eco thrive soil I threw in my garden.

Owderb Posted May 30, 2020 Share Posted May 30, 2020 Coco emerged as a growing medium because of its drainage qualities and doesn't require adding anything to it The fact that coco drains that well is one reason we sometimes have to water multiple times per day In my opinion, especially when hand watering adding perlite only increase the chances of your pot drying out too quickly, especially in the warmer months I'm not saying you cant put perlite in as that is your prerogative but its certainly not needed and is a ball ache to get rid of whereas coco is a lot easier Owd 5 Link to comment Share on other sites More sharing options...
catweazle1 Posted May 30, 2020 Share Posted May 30, 2020 (edited) @Owderb In my thinking, the function of multiple waterings is to maintain a constant rhizosphere, and added aggregate increases the free flow of air within it. For the beginner - which is my main thinking here - it removes a variable that they need not mess up. I know there are a thousand ways to skin a cat but when you are starting out, the less things you have to control the better.

Owderb Posted May 30, 2020 Share Posted May 30, 2020 (edited) Thats OK if you are using an automated system but you dont want to be hand watering more than once a day as its a ball ache thats why I wouldn't add perlite like Ive said earlier I grew for years in a top fed automated system but I still only used pure coco. I also tried other mediums too like seramis but once again not mixed with anything. Feeding multiple times a day gives you all the gas exchange you need. I really cant see the point myself in mixing mediums. If in an automated system then you could use just pure perlite if you wished and feed 10 times a day Theres no right or wrong if it works for you then fine. I just like to make things simple and also think about how easy it is to dispose of afterwards Owd Edited May 30, 2020 by Owderb 3 Link to comment Share on other sites More sharing options...
catweazle1 Posted May 30, 2020 Share Posted May 30, 2020 Fair enough. Like I said, there's many ways to do things. Pick a system and stick with it until it's mastered. 4 Link to comment Share on other sites More sharing options...
Caly Posted May 30, 2020 Author Share Posted May 30, 2020 Thanks for the discussion lads, some interesting points that I’ve taken on board. I’ve mixed my coco now and will use it on this grow, then for my second I’ll go with pure coco and compare the difference 2 Link to comment Share on other sites More sharing options...

It's proven that if you use autopots with their air domes the this can increase yeild upto 130% compared to just using regular pots! Plus the easy of using the whole system. And i suppose if you wanted to top feed you'd still be able to you could just alternate or something! I personally do like to give them the odd couple of dry days threw out cycle so they become thirsty/hungry and have never thought of top feeding when in this state so maybe it's something I'll try before putting them back on the barrel! It’s like sex panther by odeon......they done studies you know ....60% of the time it works every time 1 Link to comment Share on other sites More sharing options...
SYZYGY Posted May 30, 2020 Share Posted May 30, 2020 Yeah just to add: pure Coco for me. You have to be a little careful when potting up in big jumps (1 to 9l for example) but other than that it's pour pour pour. Just don't compact it down or let it sit in feed. In flower my plants get auto-fed 5-6 times a day in 9l air pots and still I get barely any run off. If I added perlite the feed would have to be on constant! Plus, if you're digging used coco into your garden, perlite looks well dodgy. 2 Link to comment Share on other sites More sharing options...
