A few things that I've learned about growing in coco with a drip systm DTW

This is a great topic. I want to try it, but i have a few questions. I have red all the posts, but... Sorry.

So my setup will be 400W HPS with drip system ala Pico. My tent is 3.3x3.3x6 (100x100x180 in centimeters). My useful height for plants is ~75-80 cm (2.5-2.7 inch). I want to grow 4 plants in fabric pots. I can't decide which one should i buy. There is available in 3 (0.75 gallon) liters and 7 (1.75 gallon) liters. (From the 7 liters i can make a little smaller as i fill it up just 4-5 liters for example)

Can you give me advice on the medium size (pure coco) if i will grown:
(perhaps same stains per round)
- pure indica strains
- indica dominated strains
- hydrid strains (like 50-50%)
- sativa dominated strains

Week 7 using HGO dtw method try it people you wont look back :D

These are in 5.7ltr pots

I'm on the edge. Of what I'm not sure.

Hydroton in the base of the pot will just give you a perched water table and less room for roots to grow. The root ball in that pic looks fine, fwiw. Multi feeding coco dtw ftw!

Please help me. What kind of pot should i buy for this setup? I am serching for this info, but i can't see exact informations. I do not want under/over size. My goal is all in all ~300 gr (or 10 oz) per round. The round will be indica dominated strains. (Blue cheese)

Dont know what country your from but in the uk rhizo pots(fabric pots) in sizes 1ltr,2ltr,3.8ltr,8ltr,12 ltr and think they go upto 50 or 60 litre.

I use 8l rhizo but i have more headroom and i think that maybe on the large size, unless you was doing training or scrog.

Peace.

Yes only not too dry

When they're that small it's easy to get the coco too damp in that size pot, as soon as roots are poking out all around the bottom then gently water to run off, but make sure it can drain away and not sit in a puddle

Feed them every time

Hello All,

First of all I would like to say thanks to all the contributor here. It's such a great thread with so much information to learn and all kind of great helps.

I am a new grower on my first run, therefore sure will run into many problems and definitely be asking a lots of question. I would like to thanks in advance and hope to learn to be a better grower.

Question: What is a consider a wet and dried period?

to help me have better understanding, please help explaining more in details.

My few example of wet and dry; Veg Stage Day 1 - 7. Plant in 3.8 L (0.8 Gallon) Air pot or should i have a smaller pot for Veg day 1-7?

1. Feed the plant once to run-off and not feed them again for 3-4 days? Then feed them again when the Coco are still wet?

OR

2. Feed the plant once but NOT to run-off and not feed them again for 3-4 days and let the Coco completely dry out then feed them again?

OR

3. Please give an example in more details so I know exactly what to look for when I feed them for the first time, how long should I let them dry out and what SIGN do I look for before I feed them gain?

Thanks again guys, looking forward to learn.

Rice

Hey guys, I am looking to build an automated drip system for my 4k stadium. I got my pump, tubing, tees, reservoir, just need my pressure compensators. Any one wanna share what you think are the best pressure compensated drippers?

I am running 80 plants on 4 shelves on both walls. 2 gallon smart pots. Top shelf is about 6 ft high. 10 inch drop on each shelf 10 inches out.

I have pulled 7.5 lb last round hand watering, want to up that a bit.

Do you guys water day and night.?Or just daytime.

Hey PF...I ran vertical racks with angled shelves on all 4 walls with 64 plants using 3 stacked 600`s at several locations for several yrs with dialed results , and the biggest hurdle is the "head pressure" of the pump to be able to push juice straight up 6' while maintaining equal flow and pressure to all 80 sites simultaneously on all other levels all the way round the room....that said....

I built "Pico" manifolds with PVC and tophat grommets using 1/4" open end tubing hooked to basket stake sprayers in # 5 smartpots fed once a day DTW....now....

With smaller containers you`ll need multiple feeds depending on how hot it stays in the room to prevent premature drying of medium that causes residual salt buildup that in turn causes ph imbalance and lockouts .....but....

I never fed during lights out so as to maintain "moist" but not wet rootzones....fully recirculating hydro setups feed 24/7 to maintain dissolved O2 in the medium`s solution it sits in for life support...anyways....

If you go with pressure compensated drippers , be sure to employ "dripclean" to prevent uneven flow and distribution to each plantsite from clogging that`s inevitable and will happen at some point in the game , thus why my open ended drip tubing always performed without a hitch....and hey....

Maybe drippers have gotten better in the last few yrs , but just remember .......keeping a check on 80 plants with automated feed can be a drag without proper planning and execution....regardless....

Good luck and....

Peace.....DHF....:ying:......

Hey DHF, definitely using dripclean. I have bought a 1/5 hp sump pump with 25 ft of head pressure. I am hoping this will be enough. I am sure this will be a learning experience. I won't have plants in till October so I have plentyof time to tweak things. Trying to reduce the work load and unlock the potential of multi feeds in coco.
Thanks for chiming in DHF your knowledge is greatly appreciated.

It was learned long ago with dripclean that instead of manufacturer suggestions of 0.04 ml per gal that does well with drippers and equipment to prevent residual salt buildup , a full 1 ml per gal goes a long way to prevent total residual salt buildup in the coco as well....and.....

As long as lower ppms/ec in the 600-750 ppm/1.2-1.5 ec range across the board are maintained for dialed results , .with lower ppms/ec , DTW all but needs no runoff with dripclean @ 1 ml per gal consistently in the rez.....that said....

If you use vinyl tubing , punch tools and fittings for feed instead of hard plumbed cpvc with tophat grommets , make sure to put feedlines in the drain zone where all leaks can runoff to a sump or drain , cuz they will leak at some point....bet on it....

I put all my feedlines behind the plants in the troughs that drained with equal sized tubing to each plantsite for proper pressure flow and distribution of juice.....regardless....

Once a feed manifold is pressurized , with all things being equal , either with pressure compensated drippers or open end tubing hooked to basket stakes , once dialed all plants will receive the same amount of juice where there`s no drowning 1 plant and starving another......anyways.....

Just tryin ta help from all those yrs.....Good luck and holler if I can help....PM`s always open so as to not clog threads..........

Thanks again Dhf, I am sure I will be picking your brain as the build goes on. Much respect for the experience.

Invaluable info here. I switched from .4ml to 1.0ml based on one of DHFs posts on the girls got skills thread and I stopped having lockout issues ever since. Saved me a ton of nutrient in runoff too. Thanks DHF

Hey Waxy - that's the exact question I was going to ask.

I have plants that are a few weeks into veg. Is there a way to slowly introduce dripclean so it doesn't mess everything up? Or do you have to start from the beginning and that's just the way it goes.
