My temps have been good (high 70s to around 80 to 82 with lights on), and most other conditions seem to be dialed in pretty well. It's a pheno hunt, and I have 5 distinct phenos, so it's been a challenge to find the "sweet spot" that favors the most plants. Next step is that I have multiple clones of about 8 plants, and I'll do another SOG with anywhere from 3 to 7 of each (divided into two tents; one for the sativa phenos and one for the indicas) and compare them side by side. Then they'll have a fair chance, because with 26 widely varying plants crowded into the same tent, some plants that might had a lot of potential are just not going to hit their mark because your nute mix or feeding schedule or whatever is dialed in for a different pheno.

So we'll see. As I said in another thread, trichome coverage is not always a direct indicator of potency. I may have some pleasant surprises in store for me when it comes time to blaze up.
Hitting it with some good UVB will help bring out some oil in this critical stage. UVB T5 bulbs are usually $30(Hortilux) or less. Either way, Id like to see another update or two on it as time goes on

1 week out from pulling my first canna coco run. Two 2x4 flood tables. Both Canna nutes, one side 600w Sunmaster Full Nova MH with 270w blue LED, other side 600w hortilux HPS and 270w red led. Ran slightly lower than directed and still got some nute burn. next run doing a side by side with full line vs coco a+b, golden tree and cal mag.

ya, if you were to use the recommended feed chart, could you imagine how burnt your tips would had been? holy hell. i have read journals where growers were giving em the full 15 mL. Any strain i have had would be FRYED mixing at their suggestion.

I know that if I read all 2226 post I would probably find my answer but I am impatient, that is one of the reason I smoke, slows me down.

I am not a new grower, I have years of growing outdoors and have been growing indoors for 5+ years.
Outdoors was all native soil organic grows, indoors I have gone from my very attempt was in DWC, what a fuckup that was, listened to salesman. He ended up selling me organic fert, I had 6 every nice strains gifted me by a friend. They got root rot so bad, it was very ugly.
From there I went to a soil smart pot grows, not to bad, decent yield and good bud, Querkel. Then I discovered Manifold/Manline growing and did my another grows using that technique. All of my grows since then has been using that technique but I have gone to using coco (not Canna) Hempy's. Not bad grows, but have a few problems, most my fault.

I am wanting to change methods of grow in an attempt to improve both yield and quality.

I am growing in a DYI cabinet, 4' x 2.5' x 6'. My thoughts are to use 3 gallon Smart Pots/Canna Coco & nutes, two plant SCrog using DTW. I have read to add a layer of the clay pebbles to the bottom for better drainage, not sure if I need that as I have wire stands that are one inch off the floor and just the perfect size to fit the Smart Pots. So I guess that is my first question, is using the pebbles necessary?

I am used to watering/nute my Hempy buckets by hand daily or every two days dependent on growth but from what I understand I need to water/nute the straight coco during veg 3 to 4 times and during flower up to 5 times per day. So do anyone have any idea how to build a DIY DTW water system for a coco SCrog grow? I plan on using Canna A&B at the manufacturer's recommended rates. Is this a good idea or is it to high a rate of nutes.

I need it simple and dependable.
That would be nothing like our government! :cool:8-)8) bongsmilie

If there is an experienced Canna Coco grower out there that would like to take on a protege and teach "Grasshopper" the best methods? I am an ol' dog but I can learn new tricks! :weed:

Peace out,

My thoughts are, you have top to bottom drainage with smart pots so no need for anything. Cannas site even tells you 100% coco no adatives. I recall reading on here somewhere about people having problems with the clay pellets and smart pots. Might have been icmag though. I just started growing in coco as well. 8 plants in 15 gallon smart pots with 40 liters of canna in each. Only two weeks into veg and I'm already watering every other day. Got roots blowing out the bottoms and showing half way up the sides. I'm not a canna expert, but from what I'm experiencing, you don't have to be to get great results. There line up is designed to take care of itself. Use their feed calculator and PH your water anywhere between 5.5 and 6.2 and the coco does the rest. You don't have to be exact, only in that range and the canna takes care of itself! I've done several 1:1.5 soil analasys and they all came back perfect even though my res PH continually fluctuates between 5.9 and 6.3

3 to 5 times a day seems excessive. Canna is not cheap either. You have to be daddy fat sacks to run like that. Please photo journal if you do. Im curious to see the results.

Oh yeah, I forgot. Canna recommends watering when the pots lose 50% of the water fed. They got a lot of great info on their site.

I run canna nutes and canna coco for the past year or two with no problems. I did read that with the rocton at the bottom helps with better drainage but I never used it and never had a problem. I use 2 & 3 gallon smart pots because I veg short and run 6-12 plants under a light. Kind of like a sea of green with topping and lolly popping. But I run the same pheno in order to keep the same flower height for all the girls. So to answer your question what is a DTW?

Quick question, out of the bag, canna coco is ready to be used? So we don't need to flush at all? Should be ready for its nutrient water? For example, if I have a seedling in rockwool ready to be transplanted into coco, the coco should be flushed with scheduled nutrient water, then transplant seedling in rockwool into moist coco? Or can somebody detail how they transplant into coco including when to water coco. (Before or after transplant?)

Thanks!

If you are using bag coco from canna, it is ready to grow. Plant your plant, and water according to their feed chart. If you use canna blocks, you have to expand them with plain water, transplant, and water with normal nutrient water.

Blumats for auto watering DTW that's simple and dependable (and reasonably cheap). A lot of coco guys swear by them.

I've never used blumats. Always been curious how good they'd work. What would you say would be the limit of plants in one room that Blumats wouldn't be sufficient enough.

You can use it straight out of the bag but when I'm transplanting I'll always add a little Great White and Aqua Guard. Just a super small amount. I mix in 4 gallon encrements so it would be a 1/4 tsp of Great White and 3ML's Aqua Guard.
The reason I do this is because I do run to waste and a little bit each time seems more sensible since I'm always flushing salts away. So that means I'm flushing other things away. Probably pointless to others but my roots seem to love it.
I've experimented with not flushing compared to flushing every watering and I don't care what anyone says. Flushing everytime in Coco makes all the difference in the world. Even if it's just a little bit (10%) it's better than nothing. I know some people will disagree but it's my preferred method that I get the optimum results.

There's no limit. Blumats are good for plants in any container size. It's all up to you and how you setup your reservoir + lines. They have some general guidelines AFAIK. I don't use them, but many do and the results are no doubt excellent. I use a lot of organic nutrients and they aren't well suited to organics. They're great for chemical growers though. They're also great for RLOS growers. I'm using a lot of molasses and kelp/fish emulsion currently - some alfalfa with a decent base soil but it's not too strong as I've had some issues with certain plants I'm running using rich soil.

I've read both sides of the flush fence, and for myself, I only flush every third watering. I think it has do do with setup and genetics. I've been doing 1:1.5 soil tests to see how much salut build up no runoff gets. What I've found is, with runoff every water, my root zone never got above a EC of .4 with a PH of 6.0. Once I started my current program, runoff every third watering (only 10%) my root zone now has a EC of .5 to .8 and the PH 5.9. I also noticed my plants responded better to the higher number. My brix went from 7 to 10 in a week. Again this worked for me with this strain, but it's not the only way, or the best way :) My next run is going to be 4 WW and 4 AK47. Will have to see how they respond.
