    Hi peeps, myself and hubby decided to move on from growing in soil to using coir instead. We have read up and prevailing advice seems to be to keep the pH in 5.5 to 6.5 range, similar to hydro. Can anyone experienced in growing in Coco coir please let us know any good hints or tips for this method? Thanks :bigjoint:

    Coco is a hydro medium so you must treat it as such. Watering at least once a day is a must, starting nutes early on due to most coco having no nutes in it. Get a good coco nute lime cana. Keep ph at 5.8 to 6.0. Calmg is a must with cococ as is a regular water only watering to keep salts frome building in the coco causing calmg issues.

    Really watering once a day is a must? Lmao I water once every 3 days I'd say it's not a must maybe if your running a straight Coco but no need for it get better results with tupur it's a Coco mix with organic matter from Oregon forests and perlite it's my favorite honestly and you can kill the game with it I worked for a company that made 120,000,000$ last year in Colorado and they run this system use tupur if your a soil grower you'll love the mix with way faster growth

    Agreed watering every day is not a must...almost ridiculous sounding...keep ph in 5.8 to 6.4 range.or as close as possible..cal mag is a must....flushing regularly is a must if u dont have good organics

    T5 n led like coco growing fursure...u can get crazy results with limted root space. Ph is everything. Organics or fox farms...cal mag is really important heard of bone meal mixing or calcium nitrate directly into coco...mycos/fungus/castingings VITAL

    We are using a third perlite in with coir. We are using cal mag supplement. Due to limited height in our grow room we have downsized our pots to 3 litre (when growing in soil we used 18 litres) ... will this still allow enough root space for good growth? we will be scrogging due to limited height. Any input much appreciated.

    If you're using 3 liter pot be prepared to feed multiple times a day when lights are on. 450-600 ppm, pH 5.8-6.2. I only allow a 15-20% run-off once a week, I never give strait water till my last feeding before harvest.

    some new coco products claim to have been pre-buffered and nutes added, any thoughts on this type? also sold compressed, but marketed as potting soil

    if its true, there should be no need for nutes or calmag till flowering stage

    Does that not seem like a step backward though pre adding nutes to Coco. Surely we have more control over what is in our pots with it remaining inert?

    This Guy is one of the few who is passing solid Information...

    OP, coco is great. To start:

    - get a brick of coco coir, I got mine off amazon. Once you prepare it for use just mix in plain filtered or RO water with Calimagic (follow instructions) I mixed my coco with 25% perlite

    - once you have your germinated seed you can place it in a solo cup with the coco. Cover it with stretch wrap and some air holes and you can place it under your light at a safe distance.

    - just give it an easy watering around the edge here and there, you want the roots to search the coco for water. but seedlings don't need much for 10-14 days so don't give nutes till after then.

    - coco needs specific nutrients, there's a few good brands like: coco advance nutrients, general hydroponics series works well, cana coco too.

    -Watering really depends on Strian, light and if there's trianing. I topped, LST and scrogged my plant. I water about 1 gallon a day. Half gallon when lights turn on, half gallon hour before lights off. I'm in a 3 gallon smart part. NEVER GIVE PLAIN WATER. If you ever do flush do it with a very low / watered down feeding. 300PPM or less.

    - ph does work well 5.6-6.5 ... Remember coco takes calcium and magnesium at 6.1 -6.2PH the most efficient. It's ok to go back and forth between levels as long as it's in range.

    For best results invest in a PH meter and a TDS meter.


    I love coco so far the growth is amazing

    Doing straight coco or coco and perlite is a drain to waste hydro setup and it needs to be treated as such. If you treat coco like it is soil you will have sub par results. Coco that is pre charged with nutes is just a light nute to get plants started and will not last long.

    So i want to try coco but have always run super soil, can i mix 50/50 to have buffer of soil and a little more speed with growth. My plants are always healthy but I get no big buds always small rock solid but small. Any advice would be great

    I don't think switching to coir or a coir blend will help increase the size of your flowers, that's going to be more determined by genetics and environment.

    My environment is good 70 to 80 degrees rh a little low in flower room 30 percent rh. Genetics are solid get them from friends in the industry who only use quality from big breeders it's definitely me or my SS. Trying it out 20170227_213535.jpg 20170227_213526.jpg

    Just transplanted babies into new mix today one cbd oj kush in 100% coco and cross of the black and 9 lb hammer seedlings into mix 50/50. Cutting edge nute line I just picked up only time will tell. The seeds i crossed so those in not expecting much just trying it out flowered one a while back that was nice smoke but I'm not s breeder by any means let alone a good grower no green thumb here I can't get it right after 2 years beginers beat me by far. I do have flush and cure down my buds are always good quality clean white ash solid stone but very little every time I'm lucky to get a zip per plant 2000 watts led

    If you were using HIDs I'd say 80F is a little too high, but your running LEDs. Also it looks like you do a lot of training. I have some plants that will actually lose yield when trained compared to just letting them go.
    I average over 2 zips per plant with 600 watts of HPS, 21-25 day veg, coir DTW. DSCN0668.JPG DSCN0621.JPG
