Late Sunday Update

Late Sunday Update

I got off track by a few days everyone, but back to update you all on what has occurred over the last week.

All of the Thai Stick are at Day 129 of Flowering. They will need at least another 45 Days to finish up properly allowing for seeds to finish developing. As each day passes I can see more and more seeds developing on the ladies. I should have a pretty good bounty of seeds from the 3 ladies to play with in the future.

In the meantime, Ive planted the 6 Durban x Thai Highflyer seeds I accidentally produced. This will give us some sort of idea what to expect, and some beautiful plants I imagine waiting to be seen.

I now have the room for those future seedlings now, because 10 of my Shit x HazeSkunk seeds turned out to be MALES!!!! Only 3 confirmed females, and one unknown at this point. Total bummer, but I already had something I was wanting to plant in case such as the case. Expect to see updates on the Highflyers in the near future.


Some crappy camera phone pics of TSF at Day 122. She's turned out amazing for her first time fully flowered out She looks more like a weeping willow than anything else. She has foxtails upwards of 5 inches long!!!!! Big fat greasy calyxes stacking on top of each other. How I love it!

Her buds look more like dreadlocks of foxtails. Hideous looking things. I can't imagine anyone would even want to smoke those fugly buds..

Support is a must with this lady and I just dont have enough by the looks of my last check in with them. Gonna have to invest in a lot more next time I run these ladies. They've really blown me away by how much buds they are offering up.

 

[SourDank]

Sucks about the high male ratio man, but I'm sure you'll have those 3 ladies shining soon. It's gonna be so odd watching you grow a line that doesn't take 100+ days to flower lol

 

[Dave Coulier]

You've incredible skills making the Thai look that good for so long.
I'm going to have to take notes on what you're doing, because you're doing it like a legend!

Awww shux! :shuffle: It takes alot of care and dedication to keep them healthy for so long, but I still can do better. There are times where I get lazy on feedings, so I know Im leaving something on the table. Each time we run these ladies they outdo the previous generation by leaps and bounds only getting bigger and better each time.

Take your notes, but get yourself a hanna suction lysimeter too if you really want to step up your game. It does alot of the hard work for me. From a 30ml sample extracted daily I know if I should feed, flush, or provide a milder feed. Notice no water only in there. Water only feedings lead to nutrient deficiencies if done too often. Im going off on a tangent, but Ive got more saved for those suction lysimeters and how they can improve your garden for another time.

Thanks for joining in and following along. I hope you'll stick around to the very end.

They're looking incredible Dave. Bet that 4 month cured Thai was amazing

Thanks SourDank. Its definitely the uplifting high you need to get stuff done. avoid it like the plague if you want to sleep though. Very clean and clear social high with loads of energy to boot. Good to start the day, but not necessarily what I want to end the day. The cobs are how I like to end my nights.

Dave I find your thread inspiring and luv your realistic approach to your educational grow.
Its like you grew out something that I have had in my head for years.
When others are over I show them your project and they have the holy Shit face on.
For now I will keep growing my Hybrids,But in the future I would like to climb Everest....Its all a journey

Déjà Vu....Ph-patrol

You're just buttering me up aren't we now? j/k. Im glad you enjoy the thread and get so much out of it. If my thread can help someone then that just serves to inspire me more and get more out of my garden. And of course share the rewards here for all to see.

I wish I could see the holy shit face on them. It gives me a kick hearing that. I like impressing people with my ladies and buds. I think Ill continue with that tradition here. hehe.

Get your sherpa ready and climb that mountain. Those pure sativas aren't as daunting as they may appear. I tend to look at as more time with my ladies I so love and care about. Why have a 2 month fling, when you can have a 5-6 month one?

HAZE OFF?!? Don't tease with that haha, it would be something to see you doing all those hazes side by side. I don't know if I'd ever leave IC, I'll just sit on the last page of your thread hitting refresh repetitively like a crazy person.

i can't wait to see how these hybrids come out, especially giving the genetics those little beans will be holding who doesn't love sativas?! Looking forward to seeing what comes from those brother

It could very well happen someday. It'll be a challenge to keep them compact. Thats alot of damn Haze to be growing at one time. Im gonna have to plan out the logistics of how I would be able to grow and flower out 25+ expected ladies. We'll figure it out and make it happen someday.

I can't imagine you're the only person excited bout the Durban x Thai hybrids. I feel like an expectant father hehe. Im so excited for whats to come. Expect lots of sharing later on as they come along.

Learn from my mistake, look at the product info for the size. I found one on Amazon for $14USD and jumped on it. Damn thing is HUGE, it must be for trees. Maybe I just need to grow trees then....

 

[Dave Coulier]

Ive confirmed another female tonight. 4/14 Ugh. So gross right? They're looking real fine and healthy right now as a consolation prize. Need a upcan into a larger container very soon though.

Ive had to tie all 3 down with some white shoestrings to keep them from getting too close to the light. They do stretch, since they have 25% of Sam's Original Haze in them.

With it being 75% Skunk they will flower pretty quickly. Buds are already beginning to form on 1 of the ladies, with another very close behind. The first time from seed, after a 3 week veg, had them all being ready by Day 110-120. It'll be interesting not having to do updates on a lady for 5-6 months straight!

You got a 3 foot model!! Definitely way too long unless you are using deep containers. 2ft+. The 30cm, and 60cm are the best ones. The 30cm work very well on 3 gallon and less containers. The 60cm works fine in 3 gallon, but I think is better suited for 5+ gallon.

Just in case you dont know your metric conversions, thats 3, 2, and 1 foot models.

Anyone else out there picked up a hanna suction lysimeter yet? Dont be the last kid on the block not to have the cool new toys.

Sunday Update

Sunday Update

Well, its technically not Sunday in my time Zone, but I still have 3 hours to do this update if you live on the West Coast. That counts as Sunday right?

Lets get to the Gypsy Nirvana Thai first. Those sexy ladies are at Day 132 now and are developing so many seeds at such a fast pace. Those seeds may be ready sooner than anticipated. That'd be a welcome development. Im looking forward to being able to devote more of my space to the Durban after the Thai come down. I think alot of Durban lovers would like to see them get front and center for awhile too.

Back to the Thai, I accidentally snapped a side bud off TSG's huge main cola, so Ive got something to sample on early. Although its got lots of under developed seeds to pick out. I dont expect anything exceptional out of it at this early of flower and a quick dry w/ no cure. Ill still enjoy it though.

Aromas range from very strong pine(TSA), to Pine mixed with a touch of Menthol/Medicine, and citrus aroma, in no order. One day Ill smell strong pine, the next day citrus or the Menthol/Med terps come through stronger.

Soil fertility levels are hanging around 900-1K PPM leading to a general chlorotic appearance on fan leaves and lots of single bladed leaves in buds drying out, which actually makes trimming later on much easier. I can easily pluck them out once they're shriveled up completely. These leaves have almost no resin on them. These Thai dont really develop very frosty sugar leaves. Most resin development is on the calyxes.

Im gonna keep fertility around this level for the time being, or at least attempt it. Too high for too long and you risk "fresh" bud growth occurring at the tips of buds. The lower portions of the bud flower normally, but at the apex of the bud, shoots out new undesirable growth. Ill opt for a slow controlled fade towards the finish line and not risk over-doing it. There's a fine line to walk with these ladies, and you can easily push them over the edge. Suction lysimeter for the win!

Ive also switched nutrients Im using. No more GH 3 part series. It has too much Nitrate N in it, and too little Ammoniacal N. Fertilizers containing NN:AN ratios too skewed towards NN will cause your media pH to shift upwards, which the Thai currently are at 8.0+. Definitely not ideal. An issue to be aware of next time I flower them out.

Im using Dyna Grow Foliage Pro 9-3-6 formula which supplies 1/3rd of N as Ammoniacal N. That will help alleviate the pH drifting up. I think Im going to switch to the Hi N pro next time as it has a bit more AN in it. Its also alot easier to just use one container that has everything in it barring silicone. I got sick of having 3 jugs with the GH 3 part series. It becomes very tedious over time.

One downside is that I can't use Citric Acid as my pH down agent anymore. It appears to causes some sort of precipitate to form. Ill look into other options.

Quick! Some pics of Durban Poison D taken with crappy camera phone I took a few days back. I dusted her tonight by taking the male and shaking it over her. She got covered in it. I should see much more seeds forming going forward. There's already some but not nearly as much as the Thai who are in the direct path of the male.


Afropips Durban Poison D and Gypsy Thai Stick F sharing the spotlight.

She's probably around 40-50 Days flowering. I dont really recall. She should be ready around Day 75...if I hadn't seeded her. Gonna have to push her a couple weeks extra to let the seeds develop. She doesn't have the same deep purple she took on during last winter, but still purple even though in the pics its difficult to tell. I can't wait for winter to return and that deep purple returns.

 

[SourDank]

Even without the full on purple she is still a sight to behold everytime

 

[Dave Coulier]

Aww thanks bud. She's been a breeze so far. Reflowered in the same container and rootball as last time. Not what I recommend. Should have transplanted but I got a wee lazy. Should be more pics of pretty Durbans in everyone's furure. Hang in there all.

Just Some Afropips Durban Poison in veg

Just Some Afropips Durban Poison in veg

I snapped these pics a few days ago and wanted to share with you all some Durban in veg. Ive since moved the lankier one(DP-E) into my flowering tent 2 days ago.

First up is DP-I. She was struggling for awhile, until I transplanted her into a one gallon container, and began to fertigate with my reservoir water, which is usually 250-300ppm. I should test her soil fertility levels because she looks spectacular at whatever level its currently sitting. Lovely lush shade of green to her fan leaves, albeit small fan leaves, but T5's tend to have that effect on my ladies. Small leaves help me fit in more plants into smaller areas, so its really a plus I suppose. I always get the largest fan leaves using HPS, but also the most heat, excessive stretch, and burning of the upper canopy.


She's currently got 7 tops on her. Id like to double that by flower. I just went and topped the 5 most most dominant tops. I left two alone to catch up to the other 5. Ive already topped DP-E I just moved into flower tent, which happened to have purple sap appear afterwards. I snapped some pics that Ill try to upload soon. Not the greatest quality of pics, but who doesn't want to see purple sap?

Please forgive the messiness of the grow area

Afropips Durban Poison E

Afropips Durban Poison E

Here's DP-E in veg a few days before being moved into the flower tent. Tall and lanky with long internode distance compared to her shorter, more compact sibling DP-I. This is the Durban who bleeds purple when topped. I wont be getting those up tonight. Too much cob today, and too much work. Im finishing off my 3rd gram of 2 month aged cob today. Too much or too little????

Im in love with cob and just can't say no to her loving embrace..

 

[Dave Coulier]

Durban Poison

Durban Poison

This is the Durban Poison who bled purple after having the tops nipped off with my finger tips. At first a clearer sap pools at the sight of the wound, but then it begins to take on a deeper shade of purple as minutes go by. After drying out completely, it looks like dried blood. Pretty to look at first, but ugly at the end.

I dubbed this plant Durban Mantis because the sites where I topped took on the face of a Praying Mantis after the sap formed two bulbous looking eyes opposite each other.

 

[Koondense]

Amazing, it's the first time I see a cannabis plants with eyes

 

[EvilCartman]

Great thread, Dave.
It's certainly helping me as I fumble along with my own GN Thai SS. Got just the one girl, and I'm just kinda winging-it with the nutrients. Certainly a learning experience. I'm sure I tapered off the N too soon, then brought it back too much, ARGH!
I've recently noticed that unwanted elongation at the very tip on a couple colas, as I continue to struggle with the nutrient balance.

My first try at flowering it out had to be terminated early.. Boy, do these things get HUGE. She's in the corner of a 4x4 tent, and @ 15 weeks along, dominates her neighbors. Been watching for trich development, but didn't see a whole lot going on. Kinda discouraging. Must be as you note above, mainly on the calyx's.

Accidentally snapped off a top, the other day. She may make it to the finish, in spite of me.

Next time 'round will be better.

Glad you liked it bud. These Durban never cease to amaze me. More of those ladies to come in the future.

Your experiencing many of the same fumbles as I did too. They are tough to dial in. Each mistake just gets you closer to an improvement with the lady, so I view it as a welcome thing.

Huge is and understatement. They swallow their neighbors. Really got to flower small clones to have any chance of them staying in their allotted space.

Get your self a suction lysimeter and your guessing games Will be greatly reduced. It'll make your caring for her easier when you know soil fertility levels. You may struggle to keep her fed even then as mine can consume upwards of 1000 ppm during 24 hour periods under 1200 watts mh. Osmocote does heavy duty in keeping a constant supply of nutrients at the right levels. I use 6grams per gallon along with wsf feedings.

Those tops can survive nearly being snapped in half. I've had it happen from carelessness and colas getting too heavy. Wrap em back up at the wound and it'll form a knot pretty quickly.

 

[gorilla ganja]

When do we get our lesson in this " suction lysimeter" thingy you keep talking about Dave?
I can't do the a indoor grow a the moment. But next year we go legal and may be allowed to grow a few. I'm keeping my fingers crossed as this is the only way I can grow a pure Sativa up here.

Peace GG

 

[SourDank]

Durbans are looking A+ my friend

 

[Dave Coulier]

Remember those Durban x thai seeds I started awhile back? All 6 came up no problem after a few days in the old rootballs of the discarded shithaze males. Figured why waste good media and the containers aren't too big. 6" square plastic containers.

I killed one by overwatering it. Had to go away for a weekend and over did it on the watering before I left. 5 are left and healthy about a week to ten days old. Too far from the lights atm hence the etoliation.

I'll fix that soon. For now a few pics.



**Edit. I know you'll see the writing Ace mix on the side of a container. Thats not what currently growing in the pot. I grew out the Ace mix and got some nice pretty Bonzai ladies out of those containers. I think I have an album of that here.

I've got some time away from work finally so expect it tonite or tomorrow. You'll love it when growing long flowering sativas. You'll love it general!

Suction Lysimeters and how to Use them in your garden

Suction Lysimeters and how to Use them in your garden

Part 1.

Its time to share my handy little tool that I like to play with in my garden on a daily basis..

I lifted this directly from the product description on Hanna's website since it can describe it far better than I could.


Product Description

The HI 83900 suction lysimeter is built with a porous ceramic cap connected to a transparent tube for soil solution extraction. A rubber capillary is inserted in the tube passing through a rubber cap and reaching the ceramic tip.

The HI 83900 series lysimeter is an ideal tool for collecting soil solution samples and then perform quantitative chemical analysis. In this way the operator can easily monitor the level of nutrients, such as ammonia, nitrate, phosphorous and potassium, sulfate, calcium, magnesium.

The ceramic tip of the lysimeter can be used in all types of soil, and it is made of a sinterized material that does not react with nutrient elements. The soil solution, therefore, is not affected by the chemical composition of the ceramic cap resulting in precise and reliable tests.

The HI 83900 allows the extraction of a solution from the soil by creating a vacuum (negative pressure or suction) inside the sampler tube, that exceeds the soil water tension. This will establish an hydraulic gradient for the solution to flow through the porous ceramic cap and into the lysimeter tube. Typically, a vacuum of about -60 cb (centibar) should be drawn.

For better monitoring of soil solution composition throughout an entire growth period of crops, at least two lysimeters should be installed in the root zone of a representative plant, one at the upper and one in the lower part of the root zone.

For better measurement accuracy and repeat-ability, it is recommended to replicate installations in at least two more locations.


Below is the tool Im always raving about. This is the 2ft./60cm. model. It works great for 2-3 gallon containers. For 1 gallon containers or smaller, you'll want the 1ft./30cm model. For 5+ gallon containers, 2 the foot model will work alright, but a 3ft./90cm. model may be best. It looks like the 2ft model recently sold out on Amazon. Hmm I wonder why??????

The 2oz./60ml syringe I use to pull the vacuum inside of the tube. I do two full pulls of the syringe to create the vacuum needed to collect 30-40ml sized samples from the tubes. Samples can be taken daily if the user wishes.

This is the ceramic tip that the soil solution passes through and into the tube. It needs to be activated with the solution that comes with a brand new lysimeter. Take note that the activation solution is a bleach like substance and will cause you to get very high PPM/EC values in the extracted samples for at least the first 6 extracts. Maybe even upwards of 10-12. If your extracted sample smells like chlorine/bleach then discard it and continue extracting new samples until you reach the point they are 'broken in'. The ceramic cone should be kept moistened before insertion into the media. For storing long term a bucket with wet sand works very well, but I often let mine dry out and they work fine after resoaking in tap water over night.

Here is our stopper. Make sure to have that wedged in there really good. Once its in, you NEVER TAKE IT BACK OUT! Unless you are doing maintenance/cleaning of lysimeters. The reason why we never 'uncork' it is because doing so will increase the likely-hood of not getting samples extracted. I struggled with this for a long time until I learned to leave the plug in as I extracted samples. Once I left the plug in, Ive been able to get daily samples if I wish.

It will be more difficult on the hand to extract a sample when you are pulling the syringe against a vacuum(plugs still in remember), but you'll always get a sample. When done this way you are not constantly breaking the vacuum by taking the plug out as you extract a sample, then reinsert it, and pull your vacuum with the syringe. You should also leave the lysimeter in the ground alone and not fidget with it. You may need to push it deeper sometimes to get a better wedge between it and the media, but you dont want to be pulling it back out or twisting it around once inserted. Sounds so dirty..

Here is our tubing clamps that hold the vacuum we create with the syringe. I strongly urge you to buy more clamps from amazon or wherever you buy them. The one you get with the lysimeter will break at some point and you'll be pissed if you dont have any back up tubing clamps.

Part 2 will come later as I insert the pictured lysimeter into one of my durbans in the veg room under t5's. Im very curious as to what her fertility levels are. Lets find out together.

 

[Dave Coulier]

Part 2

Lets get back to our suction lysimeters and get it inserted into Durban Poison I.

This is the lovely lady who will be paired up with the suction lysimeter. Very healthy lady in veg, and Id like to know what her fertility levels are sitting at so we can try to maintain them going into flower.

Here were placing the lysimeter next to the container to help gauge how deep we need to create our hole with the bamboo stake.

Now that we have an idea how deep the hole will be, we need to create a hole for the lysimeter. I like to use a bamboo stake thats about 1/3rd - 1/2 the diameter of the lysimeter. The smaller hole we create ensures we get a tight fit between the media and the lysimeter after insertion. The stake only needs to go as deep as the tube will go. I also like to go at an angle rather than straight down.

The lysimeter has been inserted into the media to the appropriate depth, and the media around the tube has been pressed down a bit.

Now its time to attach our syringe to the plastic tubing coming out of the lysimeter and get ready to pull some vacuum. Before pulling back on the syringe, I recommend you move your finger clamp away to a spot where you dont normally clamp. You'll want to use your fingers to 'squeeze' apart your clamp spot if its compressed(which happens when you use the same spot repeatedly). Trying to pull a vacuum when the tube is squeezed shut from repeated use even though the clamp is released isn't very helpful, which is why were squeezing it back open if its gotten squeezed shut. I hope that made sense. Now that we've opened up the tube, we pull the plunger all the way back, then clamp the line shut in our normal spot. If the plunger doesn't try to pull itself back in immediately upon release, then you dont have enough vacuum applied yet. I hope you dont have weak hands. Ill do 2 full pulls of the plunger and clamp shut the line one last time, and then release the syringe from the end of the tube. You'll know you did it right when you hear the suction breaking.

Part 3 tonight if my internet cooperates with me.
