Purple Thai etc.

[Thighland]

I thought some ppl might be interested in some sativa strains I'm growing. First is the Purple Thai, which apparently has purple flowers. It was bought from a local seller, one day he said it was land race, then next day it was a hybrid.

Nonetheless the two seedlings are growing well, having sprouted on 23/9. Temps are 29 - 33 celsius, it's rainy season, so humidity is generally in the 90s. They are currently on 20/4 hrs lighting.

Potting mix is well rinsed coco, rice husks and worm castings in equal quantities (the next mix will include powered seaweed and charged bio char).

Yesterday a friend checked the lights with his meter, they were a bit low so we bumped it up to about halfway on the Mars FC 3000, at 30cm from the tops of the tallest. I'm a little concerned about light burn, as I've had problems in the past. The new shoots emerging from top look a little white. Could this be light burn starting?

The rainy season is coming to an end, I plan to move these outside to flower and would appreciate any advice on when and how to do so. I also have some other local strains and will post about them as they grow.

Your plants look pretty and healthy too. The way I put indoor plants outdoors is by slowly introducing them from shade to full Sun. Depending on how strong your area Season is, will determine how fast you move them to full Sun. In hot Summer outdoors I have to put the plants in the shade under a tree and move them into the Sun very slowly, It can take up to 2 weeks in hot Summer. However, I'm in Fall now and can put plants out directly outdoors because the Sun is not that hot. I just put 3 out for up coming fall flowers. One thing to remember is you have to cover the pots from direct Sun if you are not planting them in the ground. If you are planting them in the ground make sure you don't plant them too deep because its very easy to do. Keep us posted friend and thanks for sharing your growing experience with us.

Thanks for the info. I have a frame set up with netting and shade cloth, I will use that. Is it worthwhile checking light levels, starting at similar levels to the tent and then gradually allowing more light?

Regarding planting to deep, several plants have had a lot of stretch due to low light, with the lower trunk having no branches. With the high humidity roots were appearing from trunk, so I buried it deep to allow these to grow. I'd read this was a good idea, the plants are doing well in the ground.

If the plant stem is woody you shouldn't plant it too deeply. Plants that are planted too deep in containers or in the ground will have transpiration issues. This rule of thumb is for all horticulture plants.
One of the most common mistakes people make when growing all plants in containers is planting the plant too deep in the container or in the ground. Even in professional nurseries, most plants are usually planted too deep for convenience. In horticulture, I have learned that if I plant a veg plant too deep in the soil it can slow down growth and come back and bite me on the ass with mold. . The plant's root flair exposure will help transpiration between the water and gas exchange in the roots zone when the plant is planted correctly.

There are two main categories of roots, "Monocot and Dicot". Monocots are fibrous and Dicot is a tap root. Cannabis is a Dicot, but when the stems are rooted the roots are Monocot roots. Cannabis is a one-season annual plant with a tap root and it's very unlikely there's enough time in a season to grow fibrous above the tap root when planted too deep.

Thanks for the info, I will keep it in mind as I live in a hot climate.

Any suggestions on a good size to put them outside? Bearing in mind they are most likely 100% sativa.

15-30gal. It’s a good idea to sink the pots in the ground if possible.
You mentioned it gets hot where you are at.

 

[X15]

Or 300 gal. Depends on how big you want them.

 

[Creeperpark]

The only reason to wait is because of a frost or freeze. If those are not an issue, then put them out right away after acclimating the plant to the Sun. Good luck and happy gardening. Keep us posted and thanks for sharing. your grow.

No chance of frost or freeze, just heat and torrential rain. Is there an optimal size for putting them outside? I'd like them to be a decent size

 

[Thighland]

Three weeks old today, the plants are looking good, I think it's time to move them outside.

I'm having some problems with other plants I moved out, yellowing leaves like a lack of nitrogen. Is there anything I feed the plants to help prepare them? Now they're watered with aquaponic water at 6.2ph. They are darker than they look in the photos.

One is also showing some brown on the bottom leaves which concerns me.

 

[Creeperpark]

I always work on the outdoor plots before I put the plants in the ground. I add compost and a complete NPK amendment to the soil before I plant the new plants. You can top dress the plants with some Alfafa or blood meal to turn the green leaves darker. Be careful until you get dialed in adding anything as a top dressing. It just takes a little blood and a lot of alfalfa to get results.

 

[Thighland]

Thanks. The plots are pretty much prepared, they will spend some time in the greenhouse aclimatizing before going in the ground. There's a monsoon about to hit, possibly last for the year. The ground is still pretty wet.

There's no alpha or blood meal here, but I do have biochar composted with chicken manure, worm castings,

bat quano and seaweed powder, plus cow and chicken manure. The plants will be watered with water from my aquaponics system, as well as solids from the filter.

Can anybody guess what is causing this browning on the lower leaves? It seems to be spreading.

 

[Creeperpark]

Those are water spots from your water type or water management. If you have hard water, you may see lime deposits on the leaves.

Two days ago I moved them outside. Today is the first sunny day, very bright but they are coping. Here's a pic, they have not been planted in the foam boxes, it's just to cool the pots. They are in the greenhouse now and will remain there for a few days, it's not so bright. Once they show sex I'll pop them in the ground.

Now one month old, today I moved them into full, they are doing fine and enjoying the great outdoors.

Looking good, i hope that you have good luck with them!
