    Alot depends on what strain you want to grow,how many.to what size,how big will your containers be,etc.When your thinking about set up its better to try and think about the whole set up together as some things jusr work better with others.

    Excellent plants you have. You have put a lot of work into them. I also decided this year to start growing marijuana at home. I hope it works. I plan to begin in the fall. However, I need to know more about this since I do not know when the marijuana growing season is.
    To begin with, I plan to buy a vape pen Canada and try it out a little. However, before I start growing marijuana at home and smoking it, I need to prepare my body a little.
    So I'm ready to take any advice on this.

    Thunderfirst, welcome to confusing marketing.
    Growing plants requires photons(just a unit of measurement) of light to grow plants. The confusion starts when we try to estimate how many photons of light a fixture can produce from each watt of electricity consumed. The efficiency of a light source has a huge impact on producing light(photon/watt)-this is where using power density(watts/sq ft) can help you estimate if you have enough intensity to grow good flower. For lower efficiency lights like CFL's, at least 50 w/sq ft. HID fixture(HPS,MH,CMH) 40-50 w/sq ft. Top-tier led's like a QB can hit that same light level at 30 w/sq ft.

    Thanks Spidermite.
    It's sure nice to have good BUDS to go with good BUDS. Lol😜. My friend grew a primo outdoor crop so I think he's using me as a test on indoor. Fine w/ me.

    You should be good with that light.

    Problem solved?
    Friend is having a Viperspectra 1000w shipped to me. Special at $109.00. Spidermite suggested a 450. Hope this isn't too much. Lol 😜. Someone said there is no such thing as overkill when it comes to light. Wish me luck.

    @ Spidermite I love the new signature 👍

    You need more light. For 4ft by 4ft I use 1000 watts actual draw from the wall. But that's just me. For $130 or so a viperspectrum 450watt (212 actual watts) would do good.

    How much are you wanting to spend and is heat a major factor?

    Unfortunately, efficient leds aren't cheap and cheap leds aren't efficient. You could go HID which is cheap and works well but not the most efficient and produces a fair amount of heat. Most of the leds that don't create much heat are low power or expensive. A watt used is a watt used and about the same amount of heat is going to be produced as a by product, LEDs tend to spread that heat over a much larger area than a single bulb of an HID. Changing my HID reflector and bumping up 200w yesterday affected the temp under the lamp (went down) but the temp of the grow room stayed the same. If you don't have deep pockets (I do not) or aren't willing/wanting to dedicate a lot of money to this, it becomes pretty hard to find lots of performance on a budget.

    I use HID because I wanted to have plenty of light to flower several square feet and didn't have the money to buy nice QB or strip based LED lights big enough to do what I wanted. $150 will buy you a 100w of QB or a 1000w HPS. I have 400w and 600w ballasts and can run 150/250/400/600 watt bulbs depending on how much light I need or if things get too warm and swap between spectrums for veg/flower.

    Previous problem was lighting.
    I'm researching LED light for 28" by 40" grow room. Any suggestions? I'm thinking I should not fill the entire area with light system. How much space should be around light system? I know LEDs don't emit alot of heat.

    Don't know any of the strains. All have been topped. Trying to keep small plants due to limited space. Maybe next grow will be 1 or 2 plants of certified strains with traits I desire.

    Thank you. They leggy one maybe a sativa as I really know any of the strains as they were randomly gathered from very good med grade. This is my first grow experimenting and with good advice may achieve a starting point from which to advance.

    It will start to flower as the natural plant instinct but I think what everyone is trying to say and I would like to add is that you will not get potential yields as you would under calculated lighting setup. Along the fact that the plants are in 10 weeks old, the ideal vegetative growth isn't there. The stems are thin and leggy. They have less leaves and overall there are bud sites but there is not much area for it to expand. We will have to see how much the plant stretches and how the leaf growth goes. I think what I want to say is you will have buds but the yield won't be much. You have used good capacity pots and you are also not in SoG method so the growth should be bushy and somewhat fatten. Just my opinion, not an expert one!

    Hope these help explain my delima. Some of these have already started flowering under one LED light. I'm hoping 5 of these LEDs is sufficient. Time will tell. 🤔
