Nute & Reverse Osmosis questions For Hydro

Mine don’t die

if your houseplants don't die from your water, it's safe to use for growing

Mine don’t die, they just get yellow and just don’t grow, they hate it. I started giving the house plants RO water with jacks classic bloom booster 10-30-20 mixed every other time. They seem to thrive, the money tree is getting huge, and the orchids are growing nice and just keep blooming.

buds will grow whether they are covered or not. i don't trim hardly anything and even my lower buds grow nicely. but like treesome said, the ones that lay on top of each other could cause some humidity/mold issues.

I completely understand what you’re saying now. If I have two big fans, one oscillates, the other is a box fan. The other two are 6” fans, one is oscillating on the tent pole, the other sits on the ground blowing up from the bottom. Everything gets pretty hard wind blowing 24/7. That should help dry it out right? The humidity stays at 62% now unless I open the bedroom door and drops to like 52%. I’ve been fucking around with it today.

Make sure your ph is good and keep from over feeding and your good.

That’s the stage I’m trying to focus on right now. Trying to figure out the feeding with AN for the rest of the grow. I’m going to get jacks for next grow and do shock. I feel it’s going to be better for me, time will tell tho. Honestly though, DWC uses so much water and nutes. I’d like to do something that works, gets good results and I don’t have to fuck around a lot with so much water. I know I don’t want to do soil, not even a little bit. I’ve never grown any other types of hydro but DWC or the UnderCurrent setup.

It’s a great hobby but try not to over think it not like they will just up and die in hours if you make small mistakes.

This is honestly what I think about all the time. If they’re ok, not too hot, not underfed. I love doing it, plus the benefit of smoking my own hard work. I worry about the roots getting rot bc the waters getting too warm. It stay right around 69-74 degrees. Depends on the ambient temp in the room. With that small 170 watt peltier cooler setup I have it honestly keeps the water 6-10 degrees cooler. The warmer the room gets, the less efficient it is. But, I don’t know if it’s really working that good considering I’ve never turned it off to check temps. I actually unplugged it today to see if it jumps more unplugged. I don’t keep the res lid closed either. If I close it the heat builds up in to and raises the water temp. So I leave it cracked. Wry little light hits it and the entire tote is wrapped in thermal tape.

You heard wrong. The amount of chloramine in tap water is well below any levels that will cause any harm to your plants. Myself and tens of thousands of others have been using tap water that contains it for decades. Not a single problem from using tap water that contains chloramine.

"We treat Portland's drinking water with chlorine to kill harmful microorganisms and make the water safe to drink. We then add ammonia to the water to form chloramines, which make chlorine last longer and better protect public health."

I meant I heard it’s a pain in the ass to get out of the water if needed.

I would look at running a sterile res over a chiller of that type. Maybe run an external water pump that pushes water through a cooler filled with ice. You would only need a small pump because you don’t want the water moving too fast or it won’t cool very well but I think sterile is the way to go. I have a brand new 1/4hp chiller that I turned on once then un-hooked it and just got some Dutch master zone and some pool shock.the reason I unhooked it was because I was already pushing my electrical circuit in my space so I didn’t want to put more load on it so chiller just sits there. Wish I would have done some research on sterile before I purchased it but I have one if I ever need it down the road. rkymtnman knows a bunch about running sterile so I’m sure he could answer any questions you have about it if you would like to try it.

Maybe you should switch to say flood and drain or DTW they are both really simple and provide excellent results. I started with bubbleponics and quickly switched to flood and drain and now trying DTW with Coco also trying some hempy buckets with perlite and all seem to growing like crazy. I really like the flood and drain since it pushes all the stale air out and sucks new air in each time it floods and drains but can be challenging if you have space restrictions. All these systems can be DIY pretty cheap

how much room you think would be needed for 2 plants? I’m just growing for personal use and want to harvest once every three months. One month veg and two or a little more for budding.

More fans do not reduce humidity. Bringing drier air into the grow space does tho. My grow room is 7x9' and I just use a 12" oscillating fan to move the air around and that's been fine for the last 20 years. 6" exhaust that won't even come on unless it gets too warm or humid in there and during the winter neither gets up too high unless I'm running a 1000W light.

I’m sorry, I meant having the fans will help so moisture doesn’t build up in between the leafs, not reduce humidity.

Ah. It will do that for sure but it's not usually that big a problem. I have a 16" wall mount fan in there too but don't really use it unless I have the room packed with plants and even switched out the fan blades for one from a 12" fan so it's not such a hurricane in there.

Yeah, mine are living in a hurricane for sure lmao. I cut the door in half too so the bigger oscillating fan can still hit them with air lol

i use this in a 3x4. and then i made a drain in it so it goes into the drain instead of having to empty it all the time. it helps during lights off a decent amount.

Robot or human?

Me and a buddy were talking about this actually. We were wondering if running one in the actual room would hurt the plants. We figured it wouldn’t but then started wondering about it effect on co2. He runs a 5x5 with co2 in it. Would that effect his co2 in anyway?

not sure. i imagine you can use a dehuey in a sealed room.

Unless it has an exhaust hose for the heat it generates then it won't affect CO2 levels. I want to get one of those 3-in-1 portable AC unit's with the dual hose so it's not blowing CO2 out of the room with the exhaust from the single hose units. The 2nd hose draws in cool air from outside and blows it out the other hose so room air stays in. I don't have 750-$1000 to spare atm tho.

If he's using an exhaust fan then CO2 is kind of a waste of time and money.

You can do 2 smaller plants in a small setup and it wouldn’t take up much space at all. All you need to make sure of is having your flood table above you res so it can drain back into the res on drain cycle. I have a buddy that purchased the smaller 4’x2x4’ tents so he could put the tents up on an elevated platform that way his res was directly under the tent and it made the tents at waist height so it was really slick. Then he used small cement mixing tubs from Lowe’s with a 27gal res and it worked awesome. Just need to make sure you have height for couple week veg then flip them to flower and mainline them or LST them and you will be able to pull way more than you will ever smoke before you harvest again and you will have some extra to give friends. Pretty easy to achieve a personal stash out of 2 plants in a flood and drain setup that won’t cost but maybe a 100 bucks in total

 

[Treesomewanted77]

2 of each of these and some hose and a pump with a Y so you can use a single pump to flood both tables and then a tote for a res and whatever medium you want. I recommend hydroton to start with its super simple but you can do it so many different ways. Then just time how long it takes to flood the tables and set your timer so it shuts off soon after the table have filled up and let it drain. Set it to flood and drain 4 times in a 24hr period and should be fine. Most say not to flood during the dark but it rains at night so it’s fine to flood in the farm period. My buddy did really good with this setup and schedule. But there is a ton of options that I would choose over bubbleponics

So, I’ve been looking into jacks. I see the 321 and I see another one, 12-4-16 and 10-30-20. I guess I’m more confused then what I thought. I want to use RO water for it. The schedule @TintEastwood says it’s for the first two weeks after flip. What jacks do I get for the entire grow? I’ll add in the
mr fulvic 1mL per gal
clean kelp 10mL per gal in bloom
bulletproof SI 2mL per gallon
southern ag capful once a week in feed res
You recommend. I just want to make sure I get the correct jacks for my RO

Yeah, that’s too much
