Thanks Joe, I couldn’t see how it could be a nute deficiency and I know the temps in there are controlled, so it seemed odd to me.

I'm not sure if you're adding microbes on a regular basis. But, you could try a once a week microbe wash on the top of the soil and see what happens. It won't hurt anything. The upside is the microbes will help deliver whatever the plant is missing if they are in fact not getting something. I'm getting really well developed feeder roots growing into the compost and fertilizer layer by giving them the microbe solution every week. I had good feeder roots in the last grow with an occasional microbe wash. But, with the once a week application I have a solid mat of white roots growing up right out of the soil. It's absolutely wild. I should have taken a photo when I had the plastic cover off on Monday.

Are you talking about mycorrhizae?

Yes, fungus, but also bacteria as well. Yes, mycorrhizal fungus like Glomus aggregatum and Trichoderma reesei but also bacteria like Lactobacillus and Bacillus licheniformis. There are a bunch of others too, but you can usually find products with a mixture of all of them. The nice thing is the good bacteria and fungi crowd out the bad pathogens in the soil such as powdery mildew spores living in the soil.

hmm so as I am getting the flower room set up and looking to make a giant scrog screen (57" x 57") a thought occurs to me... how the hell am I going to reach the back of the thing... any suggestions? Just go under? lol

I've been adding some of this to my soil, what do you think?

Oh yeah, that's gonna be tough. Mine is only 3 feet deep and that's about the max. I can reach and prune. Do you have solid walls or a tent? If you have solid walls you could mount pipe rails on the sides to be able to grab and lean over the canopy. I have one that I clip my fan to and it's pretty handy for leaning into the closet and doing work.

I had my screen set 8 inches above the pots last grow and found that was much too low and couldn't effectively prune the underside of the canopy or add soil amendments. I set it 13 inches above the pots this time and it is much better for maintenance.

well.... this is going to be a height issue i think lol... what happens when you dont look on your sips for 2 days... also a shot of the flower room as I re do the door way with a new temp doorway ( have it all framed and ready for a 36 inch interior door and will be adding plywood and possibly insulation to the small framing that isnt done. For now its all just panda filmed.

unless you have a cover crop, all but one of those mycos are useless & even if you do, just 2-3 are. If you wanna include a range of good fungi make an IMO from the KNF school of thought. If your looking for a range of laboratory and/or beneficial bacteria i like Biorighteous from EJ.

You don’t need a cover crop if you’re using a plastic mulch layer. It essentially works in the same way by protecting the microorganisms from light and from drying out. I agree you need some form of mulch whether it is a cover crop or some other material to have it work effectively. You don’t want the top few inches of soil to get crispy dry.

i was just saying that in reference to the 16 different mychorrhizal fungi in that rainbow product. only one colonizes MJ. if you had clover and cereal might get use of 2-3 of em. Glomus intraradices/ Rhizophagus irregularis are the same & i think there 1-2 other names for it. I only know of that one type that'll colonize MJ and ive only ever heard of one other, which is a type that colonizes alder.

Week 4...

Also, the clones in the middle of the Dewey Mister grew roots better than on the perimeter. Next time I will rotate them.View attachment 4115484

Looking great man! The stretch on that one side is no joke and I think I will have a very similar situation going, hopefully I can control it as I go into flower. How long have your clones been in? I took 5 or 6 from each of my 3 plants hopefully can get some keepers. I have had kinda hit and miss success with cloning and not really sure why.

Here are some pics of her ladies in their new home and the clones, hoping I can not kill these ones and can keep some control on this massive stretching, hopefully some more fun pics to come in the coming weeks! Flower time!! Excited to see how this turns out with this light combo!

Thanks, yeah the stretch was ridiculous for that plant. I think it has topped out thankfully. Sort of enjoyable to see a plant go that bonkers.

I kept the clones in the bucket for about a month. It was a bit over two weeks until they started getting roots. I stuck them in soil this past weekend. I think I may grow one outside this year in a new SIPs I’ve been wanting to build.
