Existing shed. Insulating under the floor, doable but not easy at all. Adding another floor a couple inches above the current floor to add some insulation is doable (I plan on scrogging over growing a tall tree) but I am not sure how necessary such a investment actually is in my current situation.

How important is the insulation in the floor? I understand plants on the floor would make it more important considering cold roots = slow plants, but if plants are not sitting on the floor. Since my plants wont be sitting on the floor, I dont think that will be a big impact. I doubt much heat...

That is an awesome link. I'm surprised it's still up, I actually downloaded all of the books to my drive a while back. Everyone should see that

As far as I know closed cell insulation does a pretty good job soundproofing and insulating. I dont think either the roof snow would melt nor much sound escape. I am not too worried about those issues. I am dead set o the shed. For me personally it is the most convenient and I have the money...

Basement isnt an option anymore since that house is being sold and next house being bought does not have a basement. I have rooms inside I can use but the shed would be much more convenient since I regularly have family and guests coming to visit and have a room closed off to them will cause...

Ya plan is to build my own controller out of arduino (or similar item). I am totally open to using a tank over the home brewing, just seemed interesting and I am hoping there might be someone here who has tried to use home brewing solely for their co2 needs.

So you dont think the home brew stuff is worth it, should I just go ahead and do tanks then? Not a fan of buying a generator atm. Regarding ventilation, I understand how I would need to use it if I was using it for cooling but my plan was the ventilation is only for removing ethylene buildup...

A bit long of a post. Ty for reading if you make it to the end. So I am starting the planning process of my next grow. I spent a year growing in a basement in a 5x5 tent. I found that I really couldn't control my environment well. Everything was always dependent on how the weather was outside...

I mean one would prefer dull over sharp but I dont imagine it harming much. I'm sure it isn't sharp enough to cut you if you put your hand in the soil with it and nothing in the soil, worms/roots/beneficial bugs/etc., is moving fast enough to get cut.

That looks fine man. Both the smaller pieces and the larger pieces will provide aeration either way. Smaller pieces just take up less room. You can wash the dust off it you want, I do not think it will make much of a difference either way though. No need to exclude pieces smaller than 1cm, they...

I use medium sized pumice in my beds for aeration. Works great for me. On a different note regarding a post I saw earlier. Cover crop is not going to be stealing much in the way of nutrients. The amount of nutes found in your soil is going to be way more than the actual cannabis plant can...

I have encountered spider mites twice in my grow journal on this site, once was out of control due to vacay, but both times (one big and one little) infestation were taken care of with predator mites. The big infestation killed the plants but I reused the same bed and soil, without cleaning the...

What pests are you scared of bringing inside from your compost? Most pests need live plants to be a pest to cannabis, and a compost pile (minus grass growing in it) isnt going to be holding much in the way of pests such as thrips, spider mites, etc. Soil pests are not a real problem in compost...

Some latest pics. Found the spider mites. They've moved towards the top of the canopy leaving the bottom. Right there with em was some predator mites. Looks like the spider mites are losing (not too many were found)

So we have beaten the spider mites with our predator mites. No more damage being shown even on the leaves closer to the ground level that first were affected. We have 1 arise and 2 pure love plants in the bed. The Arise is getting huge, has a serious stretch. Was not ready for it and didn't...

ready to see trial #2 :)

Thanks man! Time for an updated pic. The other day I went in and committed some genocide to all the males. Time constraints (moving) prohibited me from having time to sex and then plant into the bed, so everyone went in together and while it will hurt overall yield, I will have something to...

Why does it require the exchange every minute instead of say 15 minutes? In a situation where the plants are 4-5" below ground level and 11-13" from the ceiling, temperatures at plant level should remain pretty constant without needing an air exchange per minute. I feel like exchanging air every...

I plan on building it sub ground to help with the temps and it would be the same as if I was running a carbon filter in the greenhouse, but cheaper over time. And yes, I'm thinking a big pipe, not just a standard 6in like for a tent. Greenhouses can have exhaust fans, this would be that just...

So i am hoping to build a greenhouse in the coming months and my goal will be to keep it odor-free. It will be a solid greenhouse, not a hoop house or similiar. My idea comes from how commercial compost facilities will use finished compost /mulch to cover the static piles, creating a bio-cover...
