SIP thread -- (Sub-Irrigated Planter)

Nugnewbie said:
Hi @GrassBurner , I am a new grower and have 2 City Picker SIP, each w/ 2 plants in each. I am 20 days into flower. How long did you veg for to almost fill your 4x4 with one plant?

Looking back through the pics, looks like 7 weeks. I took 21 cuts off the plant around week 4 or 5, probably slowed her down a little, but she is thriving now :blsmoke:

yup, the runt on the right just never took off,, i couldnt cut it down so its alive down there hahah, well first time filling the box with one plant, the big plant is a praying monster , gonna be allot of bud come harvest

Hell yeah! I'm doing 2 per box this time but they are clones of the same plant (in each box) with almost no training and flipped at about 8" tall. I probably could have topped once, but they really do grow to fill the available root space
 
i would sure like to have a second grow space, with my son and his GF living here, and they both smoke me under the table, i am doing 2 winter grows in my little wardrobe just to keep up, they are enjoying some autos i grew outdoors last summer (thanks Rob) but they have plans to head off to college next fall,,, so it will probably be the usually grow box,,, i have ran so many grows thru this box since it got put together,, with the SIP and cobs this thing is almost auto pilot most of the time,,,

looking forward to seeing your grow progress, its surprising how big they get in these sips,,,

I think I'm actually around the same time as you - 4.5 weeks of 12/12. They're starting to chunk up a bit. Right side:

I have flowered this plant 3 times and kept a mom for a year and a half. She's always done that crinkly leaf thing ever since she was a baby, in the same space/soil with other plants that look normal. I keep her around because the smoke is my favorite. I think either she is very finicky/sensitive to light and nutes, and hopefully one day I will figure out what she wants, or she is just a mutant and will always look funky no matter what.

This one is the night time weed. I also had a runt this round (the one on the left/front). It had kind of a rough transplant and just didn't catch up. These were the same size when I put them in.

Is it just the light showing those leaves on the crinkly one? Sure looks like it needs some Mg?
I know some strains dont like the constant moisture,cant regulate that but have you grown that strain much bigger?Wondering if it still shows the clawed leaves?
So far with my sips small plants haven't done so well,just to wet, they dont drink fast enough.

I find myself wondering if we are going to ad.nutes to the res and pour.teas over the top ect ect , why not.just grow in coco and get the full bore benefits of hydro without the work of a DWC , or go hempy bucks which is a sip with a res with nutes and get full blown hydro results , not knocking anyone I would never do that, but I gravitate towards easy inam lazy beyond measure and sips take all the work out , ,

Been thinking about this, found the https://biotabs.nl/product/pastillas-fertilizantes-biotabs/ , but seems like you’l have To PH water if am not wrong , maybe worth a try ,

I hear you about having a strain that you like and love, having a mother is a dream come true, since I don't have space to keep a mother or to even cut my own clones I buy clones from the state legal store , but they keep changing the strains , almost never the same choices grow to grow , I enjoy trying different strains but I miss old favorites, , I totally get the runt factor , I grow in really hot soil for my water only grows and this one strain I choose just never could get used to the soil and got left behind , , it finally adjusted to the soil but by that time the other plant had taken over the space

I'm not really sure, you're right there is some yellowing between the veins, it's not the light reflecting.

I thought Mg at first too, but it's mostly on the upper leaves. So then I was thinking Manganese deficiency (looks similar to Mg but it's immobile so it affects newer growth). The first time I grew her, I did foliar sprays and top-watered with epsom salts (for Mg) and a micronutrient thing and soluble kelp for the Mn, neither one made a bit of difference. Last time I grew her I didn't pack the soil in the SIP as tight (not on purpose) and it was actually fairly dry, this time it's pretty wet and she looks basically the same...

It could also be a reaction to the light intensity, because the mother plant does it when she grows close to the light too (which is just an LED shop light, not the COBs I have in the tent), and the most affected leaves are the ones that get the most direct light.

At this point I'm thinking she is just very sensitive to light and nutes, doesn't want much of either one, and too much throws her off. Next time I'm thinking of doing more training to keep her short and wide, and might go with a weaker soil mix, see how that goes.

I have a 4-foot by 8-inch shelf with an LED shop light that I use for clones and a couple micro-moms (in 4 inch square pots). All I've grown is bagseeds from some modern poly-hybrids, no big names but that crinkle leaf one has really stood out as a clear/energizing daytime high with no hard edge or burnout. I'm glad I've been able to keep her around, even if she looks kinda crummy. No stores that sell clones where I'm at (yet), but I run into the same issue with the flower they carry at medical dispensaries - find something you really like and it's not around the next time you go shopping.
 
Flipping these girls tonight. Fed them some liquid fertilizer 2 days ago, top dressing them with 3tbsp flowergirl and a cup of ewc tonight. Got another bottle of Neptune's Harvest on the way.

Dracarys in the 4x4 is filling out the net, it's been flipped to flower as well. She's been chugging water. Did a lot of weaving in the net tonight.

Dracarys in the 2x4. Need to do some training on it next.

Released predator mites, rove beetles, and watered in nematodes in all the containers. Also released some ladybugs. Anybody have any experience using any of the enzyme products out there as a preventative?

It seems a SIP and a "wicking bed" are very similar, but not exactly the same. And other than the fact a hempy is watered from above, even they have a couple similarities, I think. I have a couple questions.

1) Can these be done with synthetics (ferts, not materials)?

2) What other mediums/substrate do you guys think would work (synthetic or otherwise)? As a wicking medium?

I've read before about the various wicking abilities and limitations of different substrate options, ie: how high water can actually wick up them.

Edit: found this, just started reading. https://www.roogulli.com/uploads/1/2/5/6/125620770/research_proposal.pdf

yes I run my sips with synthetic nutes, but never in the reservoir, when you get into flower they are so thirsty that I can top water nutes in no problem. I run with a top layer of sand on soil. I fertilize with 800 ml so it doesn’t supersaturate the soil

How often and at what strength do you feed? Also how big are the sips? Thanks
 
I've used Aqua Flakes A+B with a little Multizyme in my city pickers reservoir numerous times, but only in flower when they are super thirsty. Quick fix when you're having trouble keeping up with their appetite. I don't think it's in the res long enough for more than the wicks to absorb.
