Dunno if anyone remembers these pop bottle SIPs and perforated nursery bag SIPs I was showing as SIP seedling propositions, but I’ve running them through some testing while my GG4 flowers in one 5x5, and I’m still struggling to clean up and reset the other 5x5 because I haven’t been feeling well.
Anyway I decided to keep two of plants running, one of each SIP type, and run them all the way to harvest in my little closet propagation zone. Each pot style has less than 500mm soil, same as a Solocup, the soil is 2 parts Promix, 1 part RezDog Ultra Myco Enhanced Worm Castings. (Doin the Trump capitalization thing, just to see how it feels).
The lights are cheap non-horti types, purchased at clearance prices. I know plants love to veg under them but the flowering performance, surprisingly, isn’t too shabby thus far. I do have some redder, small led supplementation I may add.
I love how the training came out on these Yumboldt Autos by Rocket Seeds, even though they are old school, small autos, I like that they fit the environment - and even in just 500ml soil they pray nonstop. That’s how you know your Sips are humming along.
I am running forced air with small aquarium air pumps into each mini-reservoir and run them 15 minutes every 45 minutes. When I started this the plants reacted strongly and positively, praying even harder and showing real growth spurts. I also experimented with keeping rez ‘too’ full and making plant a little puffy then adding air pumps and puffiness immediately disappears. Now with pumps running all the time plants won’t look over watered even slightly, no matter what I do. I am surprised how big a difference this air injection is making.
Recently I root drenched with an organic pH dropping mix I made and they loved it. I figured since the plants Germ d on Feb 1-2 that the worm castings might be done and getting acidic. Wanted to give them more calcium also. I’ve started on a weak Lucas formula for these ladies at same time and plants love it. I also have some bloom stage microbe mix that I keep using on these, and I’ve been playing with my KF and Jadam products I made last year and now have in great volume.
Anyway, these SIP types both would make great Sea of Green SIPs or used for the seedling stage as it creates SIP-type roots from day one of life and is a reliable way to avoid stalling your plants after transplant into SIP.
