Avoid These 13 Common Marijuana Grow Room Mistakes

There are common marijuana grow room mistakes most of us make.

They increase our grow room costs, cost us time and effort, and decrease the yield and potency of our harvests.

Michael Straumietis, a long-time professional grower who founded and owns Advanced Nutrients, wants you to avoid these common marijuana grow room mistakes so you get your biggest and best harvests ever!

Not Planning Your Marijuana Grow Room Ahead of Time

Planning includes checking the electricity supply system to see how many watts of lights and other gear you can run.

It also means checking the main panel, the house wiring, and the marijuana grow room electrical outlets before you lay on the big electrical load that marijuana growing requires.

Most rooms in a home are on only a 15-amp circuit.

This level of circuit can barely support a thousand-watt grow light and the fans, timers, and other gear you need.

Unless you thoroughly look at your electrical needs and electricity infrastructure before you start plugging hydroponics gear in, you could blow your panel, or even start a fire.

You also want to plan how many lights you need, how tall your plants can get, what kind of grow system (soil, ebb and flow, drip irrigation, aeroponics, hand-watering, coco coir, rockwool, etc.) you’ll use.

Will you use a grow tent or other pre-fabricated chamber?

How will you achieve adequate air exchange and air movement?

Know all this ahead of time, before you put live plants in your marijuana grow room.

Germinating Marijuana Seeds (or Getting Clones) Too Early

Many marijuana growers germinate their seeds or buy clones before their grow room is ready for plants.

The plants want good light, water, and conditions, but the marijuana grow room is only half-built, and lacks equipment and function.

It’s best to wait until you’ve created a fully-functioning marijuana grow room before you germinate seeds or procure clones.

Failing to Use Reverse Osmosis Water

Only reverse osmosis water can give you absolutely pure zero parts per million water that works best for administering hydroponics nutrients.

Only reverse osmosis water is 100% free of minerals, pollution, pathogens.

Allowing Diseases, Pests, Pets Into Marijuana Grow Room

Outside air, and outsiders, are massive threats to your cannabis plants.

Unless you bring spider mites, thrips, aphids, fungus gnats, gray mold, powdery mildew or other cannabis attackers in with a batch of clones somebody else cut, you can filter your air and otherwise guard your marijuana grow room so no problems enter.

Because once they enter, it’s hard to remove them.

Inadequate Temperature & Humidity Control

Look here for ideal grow room environmental conditions.

Many growers run their marijuana grow room too hot. The heat problem is most often caused by inadequate venting and air conditioning.

Hot conditions stress plants, provide a breeding ground for diseases and pests, and makes buds thin and light.

Also know that the best temperature for your hydroponics nutrients water is 68F.

Colder than that and it hurts your roots. Warmer than that and it can provide problems with dissolved oxygen, pathogens, nutrients absorption.

Growing Indica & Sativa Marijuana Strains Together

The problem is mostly the height, although Indica and Sativa marijuana strains have other crucial differences that also make it not such a great idea to grow them in the same environment.

If you do grow Indica and Sativa strains in the same environment, be prepared to have to adjust grow light height, plant height, and harvesting times to accommodate the differences in how tall your strains will grow, and when they’re ready to harvest.

You may also have to run two different feed programs, because Sativa and Indica often handle nutrients differently.

Using Hydroponics Nutrients Not Meant for Marijuana

At present, only one brand of nutrients and fertilizers has reliable testing on marijuana plants and are made by a professional marijuana grower.

Those are from the company called Advanced Nutrients.

The guy who runs that company has been a professional marijuana grower and researcher for many years.

He made the company’s products so you have faster-growing plants with bigger buds and more THC, taste, and aroma.

Wrong pH of Hydroponics Nutrients Water

A massively common and very harmful problem in marijuana grow rooms.

The best way to deal with it is to use pH Perfect hydroponics base nutrients that automatically balance almost any type of water to 5.7 pH, which is the optimized pH for nutrients absorption.

Not Planting Sufficient Number of Non-Feminized Marijuana Seeds.

Many marijuana growers choose not to use feminized marijuana seeds because they want the option to grow males so they can get pollen to breed their own cannabis seeds.

For example, let’s say your marijuana grow room has lighting and other structure for ten full-size female plants in bloom phase.

You plant 12 non-feminized marijuana seeds. Seven turn out to be male.

You have to get those males out of the room, whether you’re using them for pollen or just killing them.

But then you have a marijuana grow room that can handle ten blooming plants, but you only have five females.

Under-planting can be a big waste of your marijuana grow room capacity.

You don’t want your marijuana grow room to be so crowded with plants that they’re leaves are touching, but you do want to maximize the space you’re using.

Not Recognizing Hermie or Male Plants

Many growers fail to notice early enough that their cannabis plants are going hermaphrodite or male.

This can result in unwanted self-pollination and/or pollination of nearby female marijuana plants.

Inadequate Lighting, Air Exchange, Vertical Height

A quality 1000-watt HID (high intensity discharge) grow light will provide adequate light for an approximately 5 X 5-foot area.

Some people say you’re only good for a 4 X 4 foot area with a thousand-watt grow light.

Having a light mover can help increase the coverage area and light distribution a little bit.

But if you try to get by with not enough light for too large an area, your plants grow slower, you get smaller/thinner buds, you get less THC and other cannabinoids.

For adequate marijuana grow room vertical height, you need at least 8-foot ceilings.

If you’re using double-ended bulbs (which run super-hot and generate massive amounts of light intensity per watt), you need at least 10-foot ceilings.

You can’t let your plants get too close to hydroponics grow lights, or else you’ll burn them and make the buds airy and damaged.

And remember, LED and other types of non-HID lighting might work well in small chambers, with autoflowering cannabis, or with small Sea of Green or SCROG (screen of green = net-supported plants), but they don’t have  enough intensity to feed adequate light to full-size marijuana plants.

Plants Too Tall When Put
Into 12-12 Bloom Phase Lighting

Most marijuana plants stretch 100% or more after you put them into bloom phase, Straumietis reminds us.

So if you have eight-foot ceilings and an HID grow light with a reflector, and you need at least 18-24 inches from the top of your cannabis plants to the bottom of your reflector, you can’t let your marijuana plants get much taller than 3-4 feet In grow phase.

Most indoor marijuana growers let their marijuana plants get no taller than two or close to three feet before triggering them into flowering.

Improper Harvest Timing, Drying, Curing has given you the ultimate guide to harvest timing, drying, and curing, so click on this highlighted link.

The harsh fact is that many marijuana growers do everything right in their indoor marijuana grow room, and then ruin their beautiful buds by harvesting at the wrong time, and/or by drying and curing the wrong way.

“We’ve all made at least some of these mistakes,” Straumietis says. “But now you won’t make them. You’ll see increased yields, fewer problems, and more profits from your grow room!”
