please critique my new grow room

looks good, bue, please tell me its lightproof.

 

well i'll, give you credit on one thing,,,, you got all the tools to do it with,,,,

but youll proably not need that de-humidifier, as long as your intake and exaust air is,, '' equal'',,,,,, your overdoing it as far as '' equipment''goes.

dont overdo it when it comes time for your nutes to be delivered...... sometimes trying too ;; hard;; can lead to disaster.... good luck bro. and rep. to you for starting the process... good luck, and start a grow journal!!!

 

A dehumidifier can be useful in certain conditions. If ambient air around the op is very cool, a temp operated exhaust fan may not run very often, or not at all during lights-off.

A dehumidifier will both drop RH and will contribute a little heat during cooler months, better than just heating the room air. Especially nice when the ambient air is 16C(~60F) or under. RH can spike in such temps in lights-off, making powdery mildew almost a sure thing.

I run mine 24/7/365- and the free distilled water finds a use, usually recycling back into the op.

 

Try to straighten out the sharp bends in your ducts and eliminate any excess duct length; this will reduce flow restriction.

Run the op for a week with a bath towel suspended cleverly under the light but above a bucket of water, with a corner of the towel dipping in the bucket, to simulate the transpiration of water from a few plants.

Record the temps and humidity against readings from ambient air around the op. You should be able to keep your op only a Fahrenheit degree or two warmer than the ambient air intake. Note what happens to your RH especially in lights off. A peak-mem thermo-hygro is a mighty handy tool for the job.

 

your ph and ppm's?

 

100% guaranteed overwatering! The plant roots need time to dry up a little, if you are overwatering them the stay too saturated and droop due to a loss in static pressure within the plant itself. I would feed three times a day with even spacing between feedings. In addition, how much nitrogen are you giving the plants (nitrogen defficiency = yellowish color)?

 

Definitly should limit the amount of time they are saturated, so yes put your drips on a timer so that they drip for a few but shut off.

 

you must be smokin some pretty good shit, or you dont know what youre talkin about.
Those seedlings only requre minimal amounts of nutes for the first month at least, and they only look about two weeks old currently.
theyre showing early stages of heat stress so id suggest
lookin into that if I were you Bulldog!!!!
this is the second time ive read bad advice from you,
how come youre so quick to be the teacher when you have nothing to back it up.
and what is static pressure ? care to elaborate cause ive never heard this term used before today,
and i have 7 different grow books that ive read from front to back.

 

What's the time schedule for the drip ring? They do look overwatered, but i can't say that for sure. I would def put it on a timer.

It might be me but i can see it getting really crowded fast, with those buckets so close.

 

I've seen GREAT results with a system like that running 30mins every hr. Even when the lights are off.

Setup looks good, can't wait to see those babies when they are budding

 

thats not really that high if the seedlings entire life cycle so far
has been the same, but combined with oversaturation it would prolly
be just as bad as crankin it up 10 more degrees.
I dont know much about timer cycles for hydroponics cause i grow in dirt, but I do know you need to get the temp down just a lil bit
good luck you, should be fine
other than those 2 lil minor issues, your grow looks pretty sweet!

 

well shouldn't need to have your drip on a timer, I've run every one of my grows with the drip going 24/7.

The only time I've had a plant that looked like that was when there was a Ph problem. The next thing that could do it would be a temperature problem. There was also one plant that looked like that after a calcium/magnesium deficiency.... You should also try to make sure that the water going to your roots is pretty cool, if you could get it to around 60 degrees your plants would love you for it.

I wouldn't worry 2 seconds about having the drip going 24/7, just make sure that if you have any medium around their roots (ie rockwool and so on) it's not getting saturated by the drip system.

Also 81 f. is defenetly not to warm, and these seedlings will like a bit of humidity, so I wouldn't worry about dehumidifying your grow area. Maybe just around the room.

My advice actually would be to try bringing that ph up a bit to around 5.9 - 6.5, i think that's where your problem could be coming from.

edit: Hydroponic grows can handle a bit more heat than soil grows especially if the water is nice and cool

 

I grow in dirt and my ph is 6.55.
for hydroponics hes right where he wants to be, more bad advice.
leave ph alone bulldog, worry about heat and overwatering thats it thats all for now,peace
