Why Single Plant ScrOG? 0
A single plant ScrOG (Screen of Green) makes most sense as apposed to 2 or more plants under a large net. Here are 10 excellent and compelling reasons why.
- Ease of providing individual plant care - When 2 or more plants are placed under a single ScrOG net, those plants are typically treated the same out of necessity. Growers have trouble getting to plants at the far reaches of the grow. All plants are treated the same despite their strain, maturity level or health status.
- Simple to move around if necessary - If you need to pull a plant from a grow for any reason, you will need to cut the net and remove it, leaving remaining plants unsupported.
- Improved light distribution - Growers can rotate and custom adjust screen heights. Plants grow at different rates and mature a different rates.
- Easy to remove a troubled plant from the grow space, lowers risk of damage to the remaining crop
- Easier to water and flush
- Allows gardener to harvest plants individually at precise maturity
- Eliminates crawling under nets, wire or mesh
- Wheel chair / handicap accessibility
- Irrigation equipment accessibility
- A single plant can be scrogged at an optimal time in its growth cycle. Otherwise, only the most aggressive growing plants enjoy the full benefit of Screen of Green.
Laying claim to the method of ScrOG, Wolf Segal says the original concept involved a single plant. Wolf would argue that several plants under a net is not scrogging at all.
A single plant can be ScrOGged at a reasonable price in less than 2 minutes with a rigid lightweight screen such as P SCROG screens, P SCROG Portables and Smart P SCROG. Because of this efficiency, scrogging larger numbers of plants (100s) actually becomes reasonable and a more efficient practice.

Changing nutrients under a DWC ScrOG 1
ScrOGging with Deep Water Culture (DWC) presents unique challenges compared to other methods of growing under a ScrOG. The biggest issue DWC growers struggle with is topping off and changing out nutrients (nutes). However, DWC growers can enjoy all the benefits of ScrOG without ever removing the net pot, disturbing the plant, ScrOG or root zone with this simple method.
Like anything else, there may be many solutions to this issue. One solution you may find quite useful involves exchanging nutes with a pump and topping off between changes with a watering can.
Nutes can be changed using a common small utility pump found at most hardware stores.
It is best to prepare your buckets at the beginning of the grow. Drill a hole in your net pots big enough to receive the end of a garden hose and buy rubber stoppers to plug holes when not in use.
The pump utilizes common garden hoses to transfer liquids. In the case of DWC, the nutes are sucked into the pump and pushed out the other end. The flow is unidirectional so the gardener uses the pump's input to suck old nutes out. Then the pump's output hose is used to push old nutes into an empty "old nutes" bucket. Old nutes can be used on outdoor plants, don't throw them away!
The pump's hoses are reversed to add new nutrients to your grow's DWC buckets. Then the pump's input hose is used to push fresh nutes into your grow's buckets.
DWC reservoirs of healthy cannabis plants are full of robust and abundant root systems that will burn out your pump if sucked into the intake side. This is easily addressed with "hose filters" found at hardware stores. Some pumps come with filters.
The filter should be placed in the end of the hose that goes into the reservoir, not the end that screws onto the pump. This placement makes it easier to clear any accumulated debris during pumping.
Root debris will accumulate in filters during the process and should be kept clean to avoid blockage and burning out the pump.
In between exchanges, nutes can easily be topped off using a common watering can through the same holes.
Reservoirs and root zones can be kept clean through use of H2O2 after each nute exchange and/or through the use of Hydroguard.

"Grow Your Own" state cannabis laws 1
Grow Limits: An adult over the age of 21 may possess, grow, process, or transport no more than six (6) plants total, with no more than three (3) plants that are mature.
Grow Limits: A medical marijuana patient or the qualifying patient’s designated caregiver may cultivate up to twelve (12) plants if they live more than 25 miles from the nearest medical marijuana dispensary.
Grow Limits: Adults over the age of 21 may cultivate up to six (6) plants per residency. Medical marijuana patients and their primary caregivers may cultivate up to six (6) mature cannabis plants, or up to twelve (12) immature cannabis plants. With the recommendation of a physician, medical marijuana patients may be permitted to grow a greater amount per the patient’s needs.
Grow Limits: Any adult resident of Colorado may grow up to six (6) plants per person, with no more than three (3) plants in the mature/flowering stage at any time. Non-Colorado residents may not cultivate cannabis. No more than twelve (12) total plants are allowed per residence regardless of the number of adults living there. Cannabis plants must be kept in an enclosed, locked area out of view. Homegrown cannabis may not be sold to others.
District of Columbia
Grow Limits: A registered medical marijuana program participant that indicates their intent to grow on their application may grow an “adequate supply,” or no more than seven (7) plants total and no more than 4 oz. of usable marijuana jointly between a registered patient and caregiver. A qualifying patient may designate a caregiver on their application to grow no more than seven (7) plants total on their behalf. A caregiver may only grow for one patient at a time. Whosoever is designated to grow medical marijuana should tag each plant at the base with their 329 card number and expiration date. Act 241 eliminates the ability of a caregiver to grow medical marijuana on behalf of a qualifying patient after December 31, 2018 (unless the patient is a minor or adult lacking legal capacity or resides on an island without a dispensary).

Anyone who elects to cultivate marijuana plants must keep the plants in an enclosed, locked facility unless the plants are being transported. Minors, incapacitated adults, homeless qualifying patients, and registered patients in hospice or nursing facilities may not cultivate his or her own marijuana. Only designated primary caregivers or designated dispensaries may cultivate on behalf of a qualifying patient in this case.
Grow Limits: Adults over the age of 21 may cultivate up to six (6) mature plants per person for personal use, and plants must not be visible to the general public. A qualifying medical marijuana patient with a hardship cultivation registration may cultivate a limited number of plants sufficient to maintain a 60-day supply solely for that patient’s use. He or she may apply for a hardship cultivation registration if the patient can demonstrate that his or her access to a registered medical dispensary (RMD) is limited by:
- Verified financial hardship
- Physical incapacity to access reasonable transportation (an inability to use public transportation or drive oneself), lack of personal caregiver with reliable transportation, or lack of RMD that will deliver to the patient’s or personal caregiver’s primary address

He thought of ScrOG in jail 3
On October 26, 1989, the DEA in conjunction with dozens of other law enforcement agencies raided hydroponics stores in 46 states, arresting 119 people, seizing several indoor gardening shops and thousands of cannabis plants. The largest single seizure belonged to Wolf Segal (Farmer in the Sky), 12,000 + plants growing as "Sea of Green" (SOG). Operation Green Merchant became known by the early cannabis pioneers as "Black Thursday" as many people swept up were hauled off to serve time in jail.
The Sea of Green method and cloning cannabis plants were techniques learned and brought to the US from Holland in the 80s. SOG is used to create "perpetual harvests". The method involves high plant counts per cu ft/m and short grow cycles. Clones are introduced to 12/12 flowering with little to no veg cycle. Many growers cannot use SOG due to local plant count limitations.
It was the high plant count associated with SOG that got Wolf "top grow bust" recognition. And while serving time in jail, he came up with the concept of Screen of Green (ScrOG). The concept was to grow short bushy plants with longer veg cycles that were 2x3 times more productive than traditional growing methods. This method would allow Segal to have big yields with lower plant counts.
Wolf explains the concept in this video shot at IndoExpo, Denver 2017.
