Ok so I've been doing a lot of reading lately
And sqm is what's confusing me...cause I don't know what they use to measure this
Like what's if I use 2 gallons pots and fit 10 of them in a sqm? Also as planta grow they expand outwards, what if 2 plants take up a sqm? What is the standard measurement for a sqm? I am so confused...please help me
Thanks so much

sqm = meters squared, an area thats 1m by 1m (1m approx 3.2feet)

Ya I know. what I meant was if you use smaller pots you can fit more and if you use big ones you will fit less. So when they measure what size pots do they use? 2 gallon? 5 gallon? Or do they measure by plants?

Meters squared represents the floor area of your grow and is the main factor in determining how much light to use. No matter what size pots you have or how many plants, your floor area does not change. A bulb will only supply enough light for healthy growth in a limited area and floor area is commonly how this is measured.

Yes I know and I know a 1000w hps will able to light an area bigger than a sqm. But my question is what is the norm? I mean I can have 20 plants in a sqm (though that'd be a real bad idea) or I can have 10. So when they say 900g per sqm. how many plants are they talking about?

There is no norm. Every strain is different and every grower grows differently. Some people grow huge, bushy 6' plants indoors that take up more than a square meter per plant. Others will grow a dozen little ones in the same space. The Mother's Finest we grow, for example, has a Haze phenotype that cannot possibly finish flowering at less than 5' tall, no matter how small it is when switched to 12/12. The exact same strain has an Indica pheno that can finish as small as 1 foot. Different growers may grow that indica pheno as many 1' little plants or veg it out more and have 3' plants when they finish. When creating a sea of green system, you first need to know what a plant's minimum harvest size is and what size to start 12/12 at in order to reach it. Most plants need to be a certain size to yield well. Harvest weight can decrease exponentially with smaller harvest sizes.

We grow plants that are no taller than the furthest distance away that the bulb can support healthy growth. This is just over 2' tall plants and about 1' space from the bulb with a 400w.

Ya that's my question, thanks for the answer.
I will be germinaing my white rhinos soon, would you happen to know the best height to reach before I start flowering?

To keep differences in light strength and plant stretching from being an issue, it helps to measure height in nodes. The pod leaves don't count so the first node is the next, single-bladed leaves. Three formed nodes, not counting the growing shoot starting to form the fourth node, is a good rule of thumb for minimum flowering height. This where the first full-sized, 7-bladed leaves appear. Some plants will still do well flowered at one node less but many will start yielding low at that point.

I've grown Widow before but not the Rhino, and it was a long time ago so I don't recall the sizes.
