I read a little bit about heat issues in "The Bible" I guess it can cause nitrogen lockup, which then causes the problem. Our plants get too cold at night, hopefully once we warm them up we wont have this problem. I re-programed our home thermostat to see if it will make a difference. If this...

I'm losing more plants. I'm really discouraged. I had to remove some leaves today, they were crusty to the point of breaking off in my hand. The owner of our hydro store mentioned the temp fluctuation from day to night. Could that be what is causing this? We are working on correcting the...

I haven't fed them anything yet. The Ocean Forest claims to be good for 30days. I water them every other day, or after the soil feeling dry when I stick my finger all the way in. PH in the soil right now is 7. I know it's a little high, the first time I watered I didn't have the PH adjuster...

A few of my plants have leafs that are curling under at the edges. Not all the plants are doing this, which confuses me, they all have the same conditions available to them. I am using Fox Farms Ocean Forest, and also adjust the PH of my water so that it's neutral. I have a 4x4x7 grow tent, with...

It's copper hydroxide, a coating you PAINT on the pots. It's not a nutrient, regardless of what that site says. It is "chemical pruning" of the roots, the roots wont touch the surface of the pot when the coating is applied. I either want to get that coating..not the treated pots, or try the...

I wonder if any local places here have those? It would serve the purpose I'm looking for. I saw them in the High Times Sept edition. I'd rather not pay shipping on them, since I see they are $9 for the 3 ga ones..

Anyone try them? Seems like they would be easier to find than Spin-Out. I was wondering how well they work. And what size I would have to get..

Spin-Out / Microkote is not a nutrient. It's supposed to stop roots from growing along the sides and bottom of the pot. Anyone tried Super Roots Air-Pots? They stop plants from getting pot bound as well. But they are pricey. I was told by a friend that Happy Frog has to be mixed at a 2-1...

I am thinking of using Happy Frog Soil, mixed with some clay balls, with a mulch layer of clay balls as well. I don't want to use anything that appears white in the soil, as I'd like to use the old soil in my flower gardens outdoors. The white specks look horrible. I'm thinking that I could sift...

The perlite is white, which I do NOT want. That's why I thought the hydro balls would work. Happy Frog is not cheap, it's made by Fox Farm. Microkote is a paint you apply to the pots, I don't see how kelp meal would replace this..
