Nice healthy plants you got there Capt. And glad to see your using the Kit.
Growth may not be as fast as some other methods but also each individual plant maybe be more vigorous then the next so hard to tell what’s it all down too on small sample sizes. Plus I’m with you. It’s the end product I care about not a few extra leaves or colas over the entire grow.
I’ll throw in what I can recall about fabric pots.
I have seen many use the fabric pots with great success in the kit and maybe 1-2 that had some issues. From what I can remember the fabric pots air prune roots. So when in veg in 1 gallon pots. Doc suggests Plastic pots because the roots will meet the wall of the plastic pot. Then they will begin to turn and get “root bound” this is a good thing because shortly after (maybe 1 week tops) you would be scoring the roots with a clean blade. And putting the rootbound plant into a much larger pot with a lot more soil. The plant with the help of Roots powder and scored roots now spreads its legs ( roots ) and grows a lot in a short time frame.
With a fabric pot the roots don’t get bound and grow around the pot wall. They meet the fabric pot wall and just stop growing there. This makes sense to lead to a slightly weaker and less robust root system. Atleast it will slow down that root growth progression. I still believe in the fabric pot the roots will eventually fill out the pot it just might take longer.
Another reason I don’t use Fabric pots in the Kit is that they dry out faster. When plants are rootbound in pots they drink fast. Every 2-3 days they need water or will wilt.
In flower they also drink fast and I water every 2-3 days. That’s in plastic pots. So if it was Fabric it could even be as little as every 1.5-2 days they need water.
This could either be a good thing or bad. Sometimes I want to give plants more waterings in a given 70day flower cycle let’s say. Other times I’m quite happy to wait days until they need a drink.
Hope this helps Capt. I say either plastic or fabric will work well. But just pay attention to these kind of details as ur kit grow progresses. I’m sure a couple others will chime in with more thoughts.
Have a great day and you are going to love Doc’s Kit. I would also advise you to check out Dr Ziggy’s Low and Slow Drying method to ensure the final product is top notch.
