Grow Mediums I want to try hydro, you want to do hydro with me?

[woody]

I would find a nice big spare bucket that you can set the lid and plant onto while you change nutes and give the bucket a clean- if the plant gets too large to move doesnt the alien have a tap to drain nutrients?
Some other brands have these fitted

You are probably correct @sanguine. I tried to google it, but it would be strange if it didnt have a tap. It looks like the water-indicator is a tube, wich possible can be taken off, and if remove the tube it acsually looks like a "tap". So that wont be a problem

Ill take a bucket and place where ive got lowest temps and see what temps are after some hours. If i need a chiller o not..
Thank sanguine

 

[woody]

Im not sure if @Mañ'O'Green uses a chiller or not? But personally i used sm90- its like hydroguard and ive had sucessful summer grows with high water temps.
But if i had the spare cash i might run a chiller too!

 

[Journey Man]

You mean that u can have like 25°c in the bucket if using sm90 or hydrogard ? Or is that pushing it little to high?

 

[Journey Man]

Temps in water at hottest place in the room is 22-23°C or 72F. If i put them closer to inlet i will be at max 20c. So im good with watertemps. But will use the hydroguard or sm90. I can only find sm-90 at the shops when i search online. So it looking like it will be sm-90.

My res temps hit 25oc+ quite a lot. Obviously these arent ideal conditions but i had no control. I use sm90 at .5ml per litre and its the only reason i didnt get root problems.
Plenty of air in the res also helps keep roots healthy

Thank you for that @sanguine. Wow, this is like going to school again. I get happy by learning new things. Its not to often i read all the days to learn new things. The only thing ive learned for last 10 years is actually only stuffs about cannabis. I think i have read from morning to late nights now for a couple of weeks, and more it will be. Awesome.

Don't try to move a plant until you harvest it; a pump is the answer to how to change nutrients on a big plant. Install a Bottom Draw Pump in the bottom of your reservoir before planting and just pump the old nutes out a hose - easy peasy. My current grow space pumps or gravity drains my waste water out into my flower garden outside no waste and gorgeous flowers. No lifting - I have a bad back.

Don't try to mix your nutrients in the reservoir with your plants roots in it. I have a 35 gallon top off tank on a stand outside of the grow room. Water/nutes in this tank are aerated at all times. It is plumbed to carbon filtered water coming in. Outgoing it is connected to my reservoirs and the drain with valves to direct the flow. My city water is pretty good at ~ 125 PPMs. First I fill the top off tank with filtered water and aerate overnight this dissipates the remaining chlorine added by the city and releases some of the calcium carbonate raising the PH. Then normally you add parts A - B to the water and adjust the PH using PH up or down as needed then add the rest of the nutrient components. Test the PH again. Follow the manufacturer's mixing instructions to the letter. Next I do the res change by pumping it out and refilling it from the top off tank. It takes me about 20 minutes so the roots are never in danger of drying out or stressing the plant. I have my system dialed in so that there is about 25% (~9 gallons) left in the top off tank after the reservoirs are refilled. Then I simply refill the top off tank with filtered water now I have a 25% strength (of the solution that went to the res) nutrient solution to keep the reservoirs topped off during the week. I know it sounds complicated but once you do it it becomes simple.

I have run Botanicare HydroGuard in reservoir temperatures as high as 87°F - 30.55°C without any root problems! Daytime temperatures in my tent reached 95°F on many days. I run 2 high volume air pumps (redundant in case one fails) when using DWC. I live in the San Joaquin Valley of California and we average 63 days of 100°F + every summer. Now I know that lots of people will tell you your res cannot hold enough oxygen at that high temperature - Hog Wash I have 2.5 pounds of high quality bud that says otherwise.

The high reservoir temperatures I get here in the summertime are the reason I am experimenting with a rockwool block grow right now. It pretty much negates the oxygen question. Will it improve my yield? Follow the grow in my signature and we will find out.

I don't know how to stress the importance of maintaining your water level in the reservoir at a constant 1/2" to 1/4" below the net pot is to the final result. USE A TOP O TANK with a float valve in your res. Be sure to position the valve so that roots will not interfere with its operation.

I don't know if you can take an auto to 300g but this is 2 Fast Bud Green Crack Auto plants that yielded 370g cured:

Allright. Will fix so i dint have to move the plant. Ive got a drench-hole in the green room and now it will become usefull.
I will get an extra backup pump if one gives up.
Got plenty of tips here, all info is good info!

The hydroguard i cant find in the shops, maybe they know where to find it. I know for sure my rez wont get over 24c, im guessing the air will lower the temperature some degrees aswell. Maybe, maybe not.
I will probably upload some photos when its time to start up so everything is looking okey.
Its very good that you point things out, like the top-off tank, then i know for sure its something i just need to have. Shoulnt i top up with the same nutes that are in the bubbler allready? Or top up with just 25% of the nutes in the bubbler? It was little unclear or i didnt understand exactly. But i think ill ask again when we are there.
Gonna be a fun adventure. I really appreciate all help. All i know ive learned from this forum, or atleast 95%. Awesome.

That is a nice harvest. Good growing man.

I cant see your signature below your name. I think it have to do with my settings or something. I tried to find your new grow by search but i cant find it. Can you post it here or say what forum its in and ill find it.

Much karma coming your way.

If you top off with ~25% strength of the nutrients in the res it will keep the res about the level you started with. Remember that with the flow from the top off tank during the week you are just replacing the water and nutrients that the plant used.
