My mission this grow has been Temperature and Humidity control. It was all over the place in the beginning. Night and day pushed temps and RH all over the place. I broke down and bought Inkbird thermostats and humidistats. The thermostat is hooked to a space heater that is on half power and kicks off when it brings it to the desired temp and has day and night temp options. The humidistat can either kick on the dehumidifier or humidifier based on a set value range. My dehumidifier hasn’t arrived yet, but since the thermostat has stabilized the temps the RH values have been in a nice range.

Nice garden. I really like your scrog nets for each plant.

Nice garden. I really like your scrog nets for each plant.

Thank you. It really makes defoliation and watering easy. They were made by a friend of mine.

Nice start to your grow journal, and welcome to the playground.

It must get tight come watering time.
I will be along occasionally to see how you are coming along.

Stay safe, and grow well my friend,
Tok..

Be careful with that space heater. If it's the kind that heats up the red coils it puts out red light still during lights out if it's running. I think that's what caused one of my plants to Hermie. Not positive, but it seems that way. I use an oil filled portable radiator now in my grow shed. Less to worry about & a lot less likely to start a fire.

The other thing I noticed is you said you are pH 6.5. For Soil you want 6.3 pH. If you start at 6.5 you don't uptake the available nutrients at 6.3 & 6.4. The pH climbs in the soil so you have to start at the low end to take up all nutrients.

nice job. i like the individual scrog nets.

as @Buds Buddy mentioned be careful with the space heater. i use a similar one in my veg space, but i keep it below the level of the plants, and a simple piece of electrical tape blocks the light. a radiator type heater will put out more even heat.

Real nice Jim! I have to say your net setup is the best I've seen!

Yeah, a full 4x4 would be. Those pvc trellis set ups are so I can remove each plant and put it on a table to water or defoliate etc.

I will go and cover the little light in it for sure. I haven’t seen it glow coils when it heats.

 

[Buds Buddy]

I don't know why; but only green lights can be on during the dark period.

Subscribed!

Day 21 F final trim of the under carriage.
Still dealing with less than ideal RH.

 

[StoneOtter]

There's a lot of bud on those branches!

 

[KingJohnC]

The plants appear to be growing well and forming tight bud sites at the nodes with close internode distances.

 

[Tokin Roll]

Nice looking ladies @jimgriggs and clean setup.

Should be a very impressive tent come late flower.

I appreciate it. I didn’t read the yield estimates from seed provider before buying. It says 5 to 9 oz per 3x3 ft. Do you put much stock in that?

 

[KingJohnC]

Indoor harvest depend more on the efficiency of the grow methods use of effective light intensity from the light source over square foot coverage of the available area rather than only strain generalities.

The method you are employing to grow the cannabis plant spreads out the bud sites over a larger surface area to enhance available light effective flower distance over the plants canopy surface area to increase the amount of potential growth to more bud sites versus single dominant cola formation.
