it’s pretty quick to change to the reading, I’ve checked it and calibrated it, but I let it sit in for about 10sec and swirl it and wait a few more. Basically until it stops changing, so if there’s any fluctuation in the reading I keep it in. When I put the meter in the mixture it goes quickly...

Apera ph20

Before I left for work I mixed up a few gallons and the pH was down under 5.5, and when I got home 12 hours later I tested again and the pH was at 7.1, so I guess I could mix it and give it some time to stabilize. I wonder if it would stabilize in my soil if I put it in there while it’s low.

Are you saying at that pH level I am good to feed, or should I pH up? I’ve been told both but I’d like to hear some more opinions.

I am growing in soil with Mother Earth Groundswell soil, and I went ahead and got their liquid nutes on a good deal, but when I add their low dose recommend 20ml to 2gal of water, it takes my water pH from 7.5 to 5.6. Is this normal for liquid nutes? Should I let it set out and stabilize? I’ve...

My basement tent is about 65f with the lights out, and 72f with the light on. I put a heater in there, and that brings its own challenge with the humidity, but I can easily keep it above 70f lights out and 80f lights on. I'll have to experiment and see what works. I have a humidifier so that's...

I’ll have to crank up the heater then.

What is the ideal temp in your opinion? It’s very hard to get my temp up without throwing everything else off.

I found an Apera EC60 meter on eBay for $30, you should check that out. They have the PH20 for under $30 as well.

Would it be better for this temp to be cooler (65f) and stable, or for it to stay above 67 like this and go up and down between 67-71? My oil heater takes a few minutes to heat up, then hits the temp and shuts off, and then repeats. Is this fluctuation okay or could it be bad for my plants...

The humidity in my basement was getting really high and I read that exhaust straight into the basement could cause mold. I don’t know if it is true or not but it scared me lol.

I have a dehumidifier in my basement and my exhaust fan exits out of a vent in my basement. If I put it in my tent I think id just be sending the dehumidified air outside. I wonder if it would still help at all in the tent with constant circulation.

By extractor do you mean exhaust fan? if so I could turn it down I was just nervous about not bringing in enough fresh air.

I always thought plants breathe CO2 so I was a bit confused that I’d need to pump oxygen in for the plant. Is there a reason for this that I’m not considering?

Do you water with 100% RO, or do you cut it with tap? My RO water doesn't seem to be very good for my plants, but it runs through an alkaline filter and comes out at about 50ppm and 8.5-9 pH

I bought a little 700w oil heater from Amazon and just got it in there last night. it's at 70f with the lights out now, around 74f with them on, and still room to heat up some more if that's not enough. What temps would you recommend?

Do you also use calmag in your water?

Hey fellas just wondering how you guys run your air intake/exhaust in your tent. I am in a basement that is about 68f in the day and 62f at night, so keeping my tent around 70 isn’t an issue with lights on, but it gets difficult to do as the heat from the light is gone and I’m pulling cold air...

Okay thanks. I made the solution and sprayed my plants so I’m hoping for the best. I’m not sure how to like a post but once I figure it out I’ll show you some love on here.

Can foliar spray be accomplished with a regular spray bottle or would I need a mister? Also, looking up epsom salt, I see some for plants and some for soaking, are those essentially the same thing, because I have some epsom salt for soaking I could use.
