I had trouble when I tried the humidity dome. Has this been working for you ? .

Thanks for sending me the link to your grow. Man you put in a lot of Labor. Your green house is awesome and I am jealous. It's taken me two days to get through this thread, whoooo. Thanks for showing your grow and inspiring us all.

Check out the grow logs and journals. Good luck with your farming adventure.

Here is a great cabinet grow going on right now. https://www.rollitup.org/grow-journals/210479-dual-areoponic-cabinet-ceramic-metal.html

Get some pyrethrin from the hydro store or you can go to the drug store and get bed lice spray. Spray under the leaves to kill the eggs.

You might be able to put the roots from each plant into a ziplock bag and use the bag to shield the roots when you push them through the hole. .

I keep my grow room at 66º in the winter

Cleaning the roots out when your grow is done will not be a problem.

I find that 70º is the point where pythium can start to form 68º gives me a small margin and that is why I run 66º .

In theory RO is 7.0 This is very hard to measure since there are no free ions in pure H2o We are measuring the potential of Hydrogen(pH) ions that are free in the solution. Pure H2o has no free ions since they are all bound up with the oxygen ions Your probe contains a either a...

I would think that if you are not above the tree line, you can grow weed.

Here is a picture of my hempy bucket grow. I flushed with RO only(No pH adjustment) Before flushing After RO only flush There is no reason to pH adjust the flush. If you are using RO or distilled water, you should not try to test the pH, as this will degrade the probe.

You do nice work.

So far I like the PinPoint meters. They are not temperature compensated, but they work well if you keep your calibration fluid the same temp as the nutrient rez. Using a chiller also keep the rez temp closer to constant and that contributes to more accurate readings on your meter.

Three things affect the amount of DO in your solution. • Temperature • Salinity • Altitude above sea level To increase DO you can: lower the temp, reduce your nute loads, and move to the coast. I am sure you will see improvement in your grow, if you lower the nute loads (try...

Check ebay= PinPoint American Marine pH meter

You need 35% H2o2 You also need to go to walmart and go the baby aisle. Get the baby medicine spoon and eye dropper graduated in ML The baby medicine spoon holds ten ML and is usually graduated in 1 Ml increments. They eyedropper is 2ml and is graduated in 1/4 ml increments. These tools...

Be sure your calibration fluid is the same temperature as your rez, when you do your check. I calibrate at least once a week. Try not to bang your probe or it may need re-calibrating. Try to limit exposure of your probe to RO. Try to purchase a meter that is accurate to.01 not.1

I noticed your stems on the fan leaves look red or pink. I think this is an indication of the pH being too high. Be sure your calibration fluid is the same temp as your rez, when you check your meter. If you are happy with the calibration, then you may need to shoot for 5.5 instead of 5.7

Please post a link to your picture grow log. If you don't have one, then you need to be careful. You are not making friends with your blanket statements and no proof to back up your words.
