Small space DWC 1st time grow...pray for me!

Well the plan is to transform this former shelving into a grow box. The dimensions are 18"×36"×60". Like I said working with limited space but even a miracle needs a hand...so I'll try to give as much info as I can on my process or plan if you will...and please believe all knowledge is greatly appreciated. I may not know but not afraid to ask.

Ok wife surprised me and ordered hydro kit. Little did she know it was for fresh herbs...when the package came the look on her face...priceless. Anyway got some decent seeds from a bag of something. But for first run purposes I'm willing to experience the grow if you know what I mean...get technique down, familiarity with plant life cycle and try to perfect my grow space or at least get themax out of it.

1st pic is completed boxing on frame
2nd is lined with mylar...that's the hydro kit inside.

I built this unit which I plan on transferring my unknown seedlings. I used an old aquarium pump but I might use the little pump that came with the mini unit to get as much O2 as possible to roots.

I'm gonna use these air stones.

My AN sensi grow A/B comes today. Along with meters to measure ph and ppm. I brought a root stimulator I saw in home depot thst wasn't very expensive( close to my limit on funding for the week) but anyway want to get the unit up and running and get seedlings transplanted.....the fact that they're starting to curl down I'm thinking they're ready to feed.

Look what just came! Time to get to work!!!

Ok....put it together. Res is 15gal/56.78L. When I checked ph and ppm..initial readings were 7.41ph and 108ppm. Ok I used 60ml Sensi A/B and 100ml root stimulator... I figure these were a good starting point to introduce nutes. Mixed in food let it it agitate for about 5min and tested it again...ph 6.14 and ppm 462. It was close to lights out so I will let it role and check again at roll call! I guess my question here would be are those parameters good? Or should I just observe what happens?

I know my bastards are lookin ratchet!!! I'm working on it! New light was defective so that is a little setback.

Looks fine to me. Those are little seedlings? Maybe a little high on the ppm.

Ok will monitor the situation. Thanks

Ive had those air stones before dont they float?,get the round cylindrical type.

You need bubbles popping under each net pot,water level 1/4" below net pot.

yeah I noticed that... I was also considering a larger pump...one with more output.

Looks like a nice little cabinet. Do you have ventilation in there?
If I was using that unit I would choose the best 2 plants (assuming there female) and eliminate the rest. Hopefully they would be at either end. Then scrog them to keep everything low. You should have your res temp around 18 celcius. A small USB fan pointed at or near the seedling helps strengthen them. Airflow and fresh air are critical especially when plants get bigger. I know all too well from my first grow. I also agree that your ppm are too high. They would be fine with .5ml per litre. I doubt you will ever need to go above 700 ppm even in flower.

Thanks bro.....

Well after some rough times with ph and light issues. My other option came. I moved two plants with strongest roots into the 3.5gal buckets...up the pump and air stones...placed 3gal of purified water in each initial ph was 7.42. Used 1.5oz Sensi A/B ph dropped to 5.56 in each bucket. The tent is 2'×2'×4'. I have 150watt led in there with another on the way. I put the desktop fan in for air circulation. Oh yeah ppm was 636ppm. Is that cool? Ummm what else??? Hoping that I can get them back on track...cause planning on letting them veg another 3/4 weeks. Is that a good idea?

This is new pump.

My opinion is that they are burnt pretty bad but we already mentioned that your ppm are too high. Don’t pay attention to the directions on those bottles it’s too strong.
There are ph buffers in that fertilizer and I highly doubt ph was the culprit. The buffers should last a few days at least unless your water is way different then mine.
How do you get the heat out of your tent? Any air extraction taking place?

In the back I have to holes I use to vent during the day...ok about ppm what would you recommend?

Try about 300 ppm I think they will be just fine for a while at that.

So should I drain and refill using lower ppm?
