check out the new setup

So I was moving right along with my grow, germinating seeds like crazy and putting them in soil. They were all doing great, slightly slowed growth from learning how much water they needed but healthy plants all in all.

Then the weather started getting warmer and I had to buy an air conditioner for the room, and it started to throw everything off. I would water at night and come back to check the soil and it would feel really cold. Before I knew it, my seeds were turning to mush and my plants started getting realllly sick. My temperature thing would read like 70° at night, but apparently the soil was getting much colder at might when it was wet.

Since my closet was really cramped and I wanted to clear it out anyways, I went in search of supplies. I just had my plants sitting on a table in some trays, and when I would water it would puddle up in the corners.

My plants started to suffer from a phosphorus deficiency BC it was being locked out from the cold. I bought two heating pads to put under my trays and run at night, but they come with this damn auto-shutoff function, so they would only run for a half hour and then shut off. Furthermore, all of the energy was being transferred into the water in the trays, and so instead of the energy heating the soil it was used by the water to change from the liquid to the gas phase. And then I would fall asleep, so basically all they were doing was drying most of the water out of the tray and then shutting off before they actually heated anything.

So I made a setup that allows my runoff to drain in a controlled fashion. I found a lid at walmart that was perfect to use as a tray, and has all these little channels for the water to drain. I did a little work with the heating pads and managed to bypass the auto shutoff feature and leave them on high, and then taped them to the bottom of the lid. Here's what it looks like:

The channels work perfectly to keep the water from sitting and keeping the plants soggy. This was a huge problem for me that constantly led to over watering. I drilled a couple holes and put a bowl underneath, I'll probably put a funnel and bottle eventually but at least now I have a way ton check the pH of my runoff now.

I've been running the heating pads for like 4 days, but only with the new setup for 2. Like I said, at first the heating pads weren't doing much. But now, for the first time in what feels like weeks, my plants are FINALLY THRIVING AGAIN!!!!

I had heard that if you can keep your roots at a steady 72° that it would do amazing things, and I have to say I have turned into a true believer. I really thought I was going to lose my plants, but they are def. coming back. I need to buy a timer tonight for my heating pads so they only run like 4-5 hours in the wee hours of the night. I had no other option when I was wiring them up but to make it to where they are on as long as they are plugged up.

Glad you've sorted your issues.


Its surprising how much rootzone temp can impact on above soil growth isn't it.

Oh yeah man, def. BTW Jondamon, I've been wanting to ask you-- I have already taken six leafs off of this plant
View attachment 2702814

I know you have really good results with trimming and whatnot, this plants been really sick for about a week and he's on the mends. I have already taken six leaves off, I waited until they were completely dead before removing them. I'm gonna flower this one (if its female) but I was wanting to top it, how long do you think I should wait?

You need it to start vigorous veg growth before topping for the best chance of it doing its thing.


It looks a little worse for wear.

The swolleness to the leaves looks like it needs a good feed.

Have you been feeding it yet?

Well, I gave it a couple feedings of Buddha grow when it was a little younger, but stopped feeding and put it in fox farms soil. Last night I gave it water treated with Epsom salt and calcium nitrate.

You need the new growth to look normal and not swollen or droopy, this way you know your plant is growing well and can withstand the topping.


This is how mine are before topping.




Where I generally top them.




I generally allow plants to reach 7 nodes high and then top them back to leave 3 nodes.


But like I mentioned they need to be vigorously growing in order to not get knocked back too far by the topping.

Awesome, yeah I think you are right about the feeding. Larry (my big plant, the one in question) was just starting to show his new growth being affected. Out of everything that has happened so far, the new growth has been the only part that was fine but now I'm seeing some yellowing on the tips of the top leaves, which i guess isn't really new growth. Im thinking nitrogen deficiency.

The picture quality isn't the greatest. Now that my bigger plants are perking back up should I start giving them nutes? I'm using roots organics Buddha grow, its a 2-.25-1.5 so its pretty weak, plus organic so I've not noticed any problems with burn.

The other plant that's close to his size has lost 4 leaves, but has picked up much faster.

But I figured he's old enough to start with nutes.

The two old ones are in fox farms ocean forest soil, tho, so I figured the calcium nitrate and Epsom salt would be sufficient.

If Larry had an N def it would start at the lower leaves not the top.

What sort of NPK have you got for veg/flower?

The puffy leaves look like it could just be a slight case of over watering.


Leaves should be standing proud, erect almost but not virtically.

How often are you watering Larry?

Picture 2/3 looks ok.

Slight amount of leaf edge roll up.

Did it dry out and droop at all?

Is there an oscillating fan near to the plant affected?

Theres 1 of your thrips ... or whatever you wanna call um:) they hop...like micro caterpillars that hop

Yes the way your leaf is being eaten/marked up... I get that too

use monterey garden spray with spinosad or anything else with spinosad

OK, I'm checking my girls really closely. I'm not sure, but I think my poor quality image might be throwing you off. I checked in (what I'm pretty sure is) the exact same spot and it looked like maybe a crumb of perlite or some of the lime powder was sticking to it. Just to be on the safe side I'm gonna read about these little "thrip" fellers and see if I might have the problem.

Okay, yeah I've gotten used to them being over watered BC I was using a humus amendment and it held water like a sponge. I transplanted my two big(ger) plants into ffof and added a little perlite, but it still holds water so long that it droops a day or two after I water BC its still soaked. Since I put my pads in there its better, but I'm still wanting to add more perlite. I thought my new drain tray and heating pads would help, which they have but he's still not draining properly.

Here's my NPK. I'm not sure what most nutes look like, but I'm assuming they don't look all dark and chunky like mine (I'm guessing) BC mines organic.

I water my seedlings twice a day BC they dry out that fast. Larry gets watered with about 2 cups once every other day or so. I'm definitely thinking the puffiness is from over watering.

BTW, the npk on my nutes is 2-.25-1.5. And no oscillating fan, just a stationary 20" fan and the fresh air from the intake duct, which comes from an air conditioner in the window

Larry should be getting watered when the pot has lost around 50% of its wet weight.

Then you should water until runoff occurs out the bottom.

Then you should wait until the pot has lost 50% of its weight again.
