I've done a super simple Hash Plant balcony grow with great success. The cycle ran about 5 1/2 months, the plants got roughly 3ft tall, yielding 2-4 ounces from each plant. Here is the formula which I followed....

I used an Earthbox with Fox Farm Ocean Forest potting soil, and watered with evaporated hose water. After about 1 month, I started feeding them a compost tea every 2 weeks and used neem oil during veg as needed during flowering.

Earthbox - Self watering planter box with built in resevior to prevent over/under watering.

Fox Farm Ocean Forest potting soil - The best soil money can buy. It has all the nutrients you need for the entire grow pre-mixed right into the soil. I recommend about 3-5 gallons of soil per plant.

Evaporated hose water - No need to spend money on purified water. Just fill up a bucket of hose water and let it evaporate for 48hrs.

Compost Tea - After 1 month of growth, start feeding your plants a compost tea every 2 weeks for beneficial bacterias.

Neem Oil - 2 treatments a week during veg, then as needed during flowering will keep the pests away. (I recommend the company GreenLight. They make organic neem oil that can be used all the way up to harvest.)

Follow this forumla and you will grow organic goodness.... I promise you.

The only problem I can forsee is the photoperiod. 12/12 will send them into flowering. You need at least 14hrs of light to keep them in a vegatative state. Figure that out and it is off to the races....
GROWxMOREx420 Reviewed by GROWxMOREx420 on . balcony on the equater, getting started Hi all, I just signed up and searched the forums before posting. I have the following environment: 19th floor apartment, big balcony, 75-85F, 40% humidity, 12 hours of light and 12 hours of darkness all year round. Light cycle from 5am to 5pm. Balcony faces the east and receives good light from 6-9am, decent indirect light after that. Powerful lites are on the balcony that could be strong enough to add more light time. Gets moderately windy. Rains hard in march and april. Very sunny beyond Rating: 5
