So here we are DAY1 since SOJ (Start of Journal)
We need to catch up for the last week. I have done many things for this grow, primarily building a Flood and Drain Hydro System. I am not going over that again, if you need more info on it I have documented a tutorial on its build, you can find a link to it in my Sig.

So we will get started on the good stuff the new babies:
I bought these clones from the same place I got my Blueberries Clones I am totally happy with them.
Here are the pictures of them when I brought them home:
This first one had a nice little side branch already going

Nice and dark green very healthy

This one has a really nice double stalk if done right this could be a real jewel! :) Its unfortunate that I don't have room to do a flux, I think this would be a good start.

The stalks have lots of new growth sites and should really respond to LST



The clones came in soil, so still being new to this I asked around and got some good :420: advise on the transplanting them to Rockwool.

First thing to do was prepare the rockwool cubes for transplant. I used 4" rockwool cubes split in half. I soaked them overnight with PH 6.0 DH20 Water with 1ml/G of Cal/Mag and 1ml/G of Roots Excelurator. I split the cubes in half before I soaked them figuring it would be less of a mess, and it was. Just be careful dry rockwool is ichy! :24:

Here is the soaked Cube cut in half ready for the transplant:

I cut off the side of the cup and you can see they are well rooted.

I decided that since I was going to encase them in the 4" cube I did not need to totally wash off all the dirt. I also figured the residual dirt would provide some initial nutrients so I would only water them the first day or two until I built the new system

Here I am inserting the plant into the rockwool. As you can see the roots are nice and white and healthy, now lets keep them that way.

Fold it back together and use rubber bands to hold them.

Here they are in there first temporary home until I can move my single plant BB LST. I used 4 CFL 75W for this.

Then I decided they needed more and I added my spare Fluorescent.

Here are some close up pictures of them. The transplant went well and they don't look any worse for the wear.



The next day I made some room in the main tent for the Single Blueberry and moved them into the Veg Tent. Next step start the training and get the new hydro set up.

We were going through a heat spell here so I left the tent open a lot but it was still hot, they seem to be handling the heat fine, being sativas

A series of first LST training using wire ties to lightly stress them into laying over. I do not have room for 6'+ Sativa's so if I'm going to be able to grow them they will have to lean over. But if done right it will open up many new bud sites for large Zips. Its what I did with my BB grow and I have a large number of large buds.




So a few days have passed and I have built my new Hydro System and its time to move the Cookies into the new pots for the Flood and Drain Hydro System.

I used 6" square aerated pots because I needed the holes up the side of the pot for it to work. I first laid down a layer of Hydroton so the rockwool wouldn't sit in the leftover nutrient at the bottom of the drain tray. Then a layer of rockwool cubes:

I removed the plastic from around the 4" rockwool cube and took a look at the bottom. After just two days the roots are starting to pop out the bottom! :thumb:

After putting the plant into the pot, you need to fill it with rockwool cubes. It was a tight fit and I wanted to makes sure there were no voids down the side I poked and pushed them down the side.

Top them off with some more hydroton to prevent rockwool algae. All six are done and you can see the first feeding.

Then I was informed by helpful 420 members that light shining into my drain tray is bad so I made a top for the tray from the lid and covered the bottom with aluminum tape. There is a rather humorous recount of my experience making it in the tutorial.

OK caught up with the grow to date. Will be having daily updates from hear on out until harvest.

Your clones look really healthy. I've never seen a soil to rockwool transplant. Nice work TrysHard, I'll be rooting for you the whole way.

I love the kushy earthy flavor of GSC

I'm in...lol.

Not sure what I'm going to learn here..not a bad thing, you did a great job on the last.

Just along for the ride.

Well I am going for some changes this grow once it gets into the tent. Also I think the longer veg and this being a Sativa should necessitate some adjustments for me. I also am planning from moving to a ebb and flow Flood and Drain to an Top Feed and recirculate system.

Subbed' looks good so far.

Count me in!


Love the home made dwc! I use something similar for cloning only using a mist spray! Fantastic!

Thanks everyone welcome :welcome:

I've never smoked it, like I've never smoked Blueberry, but I've seen pictures and a GS Cookie won the LA Cannabis Cup one year I think with 26% THC. So I going for it, although the training will have to go well to make sure they fit in the tent.

Thanks Welcome

The new Flood and drain system seems to be working well and the clones are looking good. I did some tightening up on the training and took some close pictures for everyone to look at. Please look and tell me if you see anything, I don't, but might as well make use of expert eyes.

Temp 84F
RH 55%
PPM 1127
PH 5.8

I've numbered them for ease of identification and discussion.
The Overview 5-20

Cookie #1 This is the V Shaped one. I should have some fun with this one.

There they are 1 week into the new grow.

Does the new growth look a little dark on the edges?
