SIP thread -- (Sub-Irrigated Planter)

[meangreengrowinmachine]

I had mixed up some em1 and molasses and water about a week ago to expand it and today made up some bokashi bran and added it to the top of the SIPs. Also have added some cal mag (always freaking cal mag issues with leds) and some of the expanded em1 to the res. Come on ladies time to take off so I can take a bunch of clones and hopefully not fuck that up this time! Lol

I've just recently started reusing my soils. No soil testing done here. Not saying I won't or wouldn't. I'm just going by what I've read on re-amending used soil, since I do quite a bit of reading. So I guess you could say I'm just winging it. I'm just playing around in a 4 x 4; and honestly, not that dependent on one grow if it does go south. I have enough stash from previous grows. I'd just start over, but with fresh media; couldn't have two busts in a row. lol

I think when you reuse it more than once or twice is when testing would be wise. By then, things could easily start getting out of balance.

I looked up the Lamotte Soil Test Kit. Like you said, it just checks for N-P-K and ph.
IDK. Seems a little pricey for just that.

I've seen some on these forums send out soil samples to Logan Labs for testing. They say it runs about $45 for there basic. Couple guys posted there chart or graph they got back, it looked pretty thorough.
Cal, mag, the micros. They have a website, think they're in Ohio.
I see Build-a-soil also uses them.
I may get to that point in the future. I'll see what happens the next couple runs.
I have one started now in recycled soil, so far it's looking good. But it's early, and it seems like deficiencies rear there ugly head in flower.

Yea, I'm not sure how the soil micro life would be in your old sips. I know I've read that life in soil slows with cooler temps. But how much , and what temps??
It may give you a little jump start with a living soil.

I wouldn't be scared of it. lol

I'm still a Novice compared to your set up. Wish I could do that. I'm a closet grower. I always save my soil mix from my last grow. Always wash those clay pebbles before use. My favorite amendment is the roots from the last plants grown in the pot. It adds so much humus. It has whatever was used previously. I never tested it but so far no gnats and everything is so green. I've been using a variety of was left over in the storage. The main ingredient added this year was some organic Miracle Grow Soil in a bag for $6.50. Not much just enough to add a little soil. When I add nutrients I never go over 300 ppm unless needed. Green really green so nice.

So for those who've had full runs, when you get to last week or two of flower do you do anything to prepare specifically?

I.e. I'm sitting here wondering if I should be trying to get any remaining water out of the rez's to let the girls run a bit dry the last few days. With these SIP deals I've let them go until chop day without really doing anything to stop them from drinking - but was considering it this time.

I gave them what will be their last watering, only using activated EM and just a dash of fulvic. Game plan being no more, let them run dry and call them ready when they start showing a little wilt. I'm around week 8 and thinking it'll be a 10 week run so the 2 gals per container should hold them over until then.

Just curious of anyone else's final week strategy and if they do anything special for SIPs.

I’ve had mixed results with these. That said I have 2 SIPs with 2 Critical Kush plants in each that are ready to chop. This strain seemed to do really well and yes, I haven’t watered them in a couple weeks. They are still in the flowering room, but moved out from under the lights.
I’m chopping this week, so I’ll update later.

i usually dont do anything differant on previous grows,, i would water and keep the light on 12 12 all the way to chop,,, BUT this time around i am letting the res run out, and let the res sit empty for about 3 days, not that i feel it wil lhelp the plants any,,, i just want the sip to be much lighter in weight when i go to lift it out, it should be about 50 pounds lighter this way, does it benefit the plants any?,, not sure, but thats why i am doing it

I do the same and basically for the same reasons (weight of all that water). I did try a test last go round not super controlled but there did not seem to be any difference in production or dry times or anything really between the SIP that continues to be watered and the one that was left dry.. sooo... I dont think that helps but my experience lol

Water soluble gypsum last 2 weeks of flower
4 gram a gallon

Gypsum has calcium and sulfur.
Two great amendments.

Adding the last two weeks, I'm sure your going for building terps with the sulfur.
I've read where sulfur = terp city.

I have been adding one c. per cf. pelletized gypsum to my soil mix at the beginning.
Now you have me wondering if I could benefit by adding more towards the end?

Yes, soluble gypsum at the end helps mobilize k, which creates harsh smoke. Also helps with shelf life.

Too much P creates harsh smoke, not K.

Sub-irrigated planter
From Wikipedia, the free encyclopedia


Sub-Irrigated Planter
Sub-irrigated planter (SIP) is a generic name for a special type of planting box used in container gardening and commercial landscaping. A SIP is any method of watering plants where the water is introduced from the bottom, allowing the water to soak upwards to the plant through capillary action.[1] It is possible to automate the watering and thus SIPs are popular with professional landscapers in buildings or urban settings. SIPs are available as products, under brand names such as Planter Technology[2] (commercial) and EarthBox[3] (consumer), Ollie Plant Sipper[4](consumer), The Refuge Garden (www.urbanrefugegardening.com) (consumer/commercial) or as do-it-yourselfprojects made from plastic buckets and boxes.[5]



Would love to hear about your experiments, projects, failures and successes.

I actually do a similar thing to this in my outdoor grows where I will sit my fabric pots about 3 inches off the ground in a solid raised bed and then flood the table with oxygen rich (from air stones) worm casting/ chicken poo tea. It wicks to the top of the fabric pot by barely touching and gives pretty great results. Like a different take on DWC's.

Chop Chop, this was by far the Easiest Grow i have every done, water only the whole ride, never saw any insects or bugs, or creepy crawly things hahah, didnt spray anything on the plants the entire grow, just poured water from my tap into the fill hole, and this happend,, gotta love the sip

I'm calling on my favorite super hero, Captain Save A Sip, if he or she is out there I am need of help. My sips have had a little neglect while I have prepared my grow area. Long story short they have had a rough 8ish months of veg because I was starving them of fresh air for a long time and watering at times was neglected. Recently I came down with a case of thrips and spider mites, lucky me, but it seems like I have been able to battle through them with green cleaner and maybe an application of azamax. I am spraying green cleaner every three days for the last 2 weeks and plan on doing so until I send them to flower and see buds.

The base of my soil is big rootz by Soil King with grow stones added

About two months ago I top coated malibu compost on top

About 2 weeks ago I added fresh worm castings and about 500 wigglers per 27 gallon sip

About a week ago I gave a light top coat with some kelp, oyster shell, and rock dust and planted cover crop which has started...

Captain Save A Sip what should I do?

You should prolly pay more attention to your plants. Flower em, see what you get. Or start over and treat em rite.

 

[SUNDOG]

Thought this would be the place to post this.
No sips, just a first time "LAB serum " run. All most done I think? Oh and some tea brewing just for shits and gigs.

Something is seriously wrong with that soil. I would make soil slurry and test the ph.

 

[1shaggyDude]

Just popped a couple of greenpoints purple canyons (topanga canyon x purple punch) into their sips. Last run was a fire og (dearkheart) and a buddha tahoe og. Ended up with 472 grams!! These sips actually make it look like i know what i'm doing.

 

[1shaggyDude]

Couple pics from last run. First one is tahoe og the other is the fire og

Hello all this is my first time recycling ffof soil so far since last grow I've given them 444 about a cup and a half with the last top dressing being about 3 weeks ago now other than that I haven't given them anything else aside from two waterings with some tm7 im in a 15 gal sip pot and have done some lst
So I'm not sure if my pots are over wicking or deficient or toxic in some form and help is much appreciated. I'm thinking its maybe a magnesium deficiency or potassium toxicity but not sure. Plant seems to wilt top looks a bit yellow and sickly I get the rusty vanes and then the leaves begin to yellow from top to base and curl but dont seem to drop off right away
