I've grown in Northern Wisconsin and Upper Michigan, where outside temperatures dip as low as -45 Fahrenheit. Pulling air directly in from outside when temperatures are low can give you some massive temperature swings. Here is my solution: (I use it year round) Having an air cooled light...

They work decently enough under minimally damp conditions. I once had a closet that shared a wall with my mini laundry room. The closet and my clothes became damp and moldy as a result. In this situation, the damp-rid was sufficient to dry the area up a bit. In a grow room, they are relatively...

On tomatoes and peppers, you want to take cuttings of 'suckers.' (The downward pointing stems that many gardeners remove because they don't produce anything.) It's pretty much the same process of cloning MJ.

They're a bit pricey. Many hydro shops carry them, especially the online ones. Sometimes they're marketed towards folks using them for extracting essential oils from herbs, etc (doesn't work as well as it does for weed though) Bubble hash oil is very pure. Great stuff. I've smoked it, but...

If you're making hash oil in those quantities, it might be worth it to invest in some bubble hash bags.

I've used 4 foot tubes in the past. I clone in pots of coco, so the length is not an issue, as it would be in a cloner. But I want to try CFLs to make my colning setup more compact. (I'd like to move it to a shelf in another room to free up some space in my grow room.

Soap is harmless to plant roots. (Read 'SOAP,' not 'detergent) Dish detergent can be harmful to your plants, but Dr. Bronner's won't cause any harm. I would use the 'baby mild' unscented variety. Add a couple drops every few waterings. The rewetting issue in peat is usually only bad if you...

That .02 of dissolved solids in the water is likely coming from the metals the water came in contact with on its trip out of the air conditioner. While the EC may be lower than that of your tap water, the water from your air conditioner could contain lead, copper, aluminum or zinc. Its...

Hey everyone. I'm looking to make my cloning setup a bit smaller, and want to try CFLs. For those of you who have cloned under CFLs, how many plants per light, and what wattage have you found to work best?

Personally, I wouldn't want to smoke hash oil made with acetone. It's like organic produce-- many will tell you that the small levels of pesticides in traditional produce aren't harmful to humans, but I'd rather not ingest poison, even in small amounts. I use Everclear or cheap vodka. The...

You can put germinated seeds directly into neoprene collars. It is a bit tricky however, and there is significant room for error--- I suggest buying a 99 cent bag of lentils from the grocery store and germinating them and trying it first with them, so you can get the hang of it. A more common...

Right on man.

I'm not sure i completely understand the question. Are you asking for ways to propagate to ensure all plants are females? If so, cloning is the way to go. All of the clones will share the same genetic makeup as the "mother." Search the forums, and you will find lots of info on cloning. If you...

WTF? Obviously a typo. I would venture to guess that they intended to say 21 degrees Celsius (70 degrees Fahrenheit)

This is a common misconception. Drain to waste in coco or hempy only wastes a small amount of nutrient solution with each watering. If you compare either to a recirculating system and do the simple math, recirculating systems with a fresh res every two weeks or so use MORE nutes. Think about...

flood and drain is a great way to get your feet wet with hydro. It's where I started. The primary difference between flood and drain and drain to waste like hempy or coco, is the need for adjusting your nutes. Flood and drain requires a bit of knowhow when it comes to tinkering with DIY...

Right on man. Start simple, and build on that with what you know.

DWC is great, but for how simple it is, there is still quite a bit of room for error, especially when it comes to pH flux and nutrient uptake. IMO, hempy or hand-watered coco have much less room for error, mmuch less tinkering with nutes, and much more wiggle room. When you're just getting your...

I'm a teacher. That's what I do best :)

Hey everyone, I've noticed a lot of newbie hydro growers with great ambitious DIY hydro projects. High pressure aero, low pressure aero, NFT, DWC, etc are all great ways to grow in hydro-- but they all have a learning curve, especially if you have never grown in hydro before. If its your...
