    id go with 3-4 for that kind of space.took over a scared freinds botched 4x4 grow an this numbskull got 8 different types in 5 gal totes with 2 sites a piece for the hydro. Some got beat out for light by others an made a big tangle mess under the lid between 2 plants. some where good but were ajoined with a lack luster partner. i use a 400 m/h with supp flouro's to bump it to 800 for my 4x4, but I use 5 gal bukcets with hydro set up. point is don't bite off more then you can chew.

    Using any light efficiently isn't about the number of plants; it would relate to the total area of your canopy.. If you have 2 plants with a large canopy, then it would be efficient enough. The intensity of the light just diminishes, of course, the further away you get from the center & bulb itself. DWC can make large plants, quickly, so a 600 Watt light for 2 would give you an almost maximum yield- if there is a good balance between your elements.

    You are correct B3RNY. For the best balance of elements the plants will need space to breathe. I can be a strain whore at times an grow 3 in a space where 1 or 2 should be. So yea, don't listen to me.

    To be honest mate do what you want under it, its all about building experience jus remember theres a good rule to work fromis gram per watt so 21oz per 600watt, so do you want to do... 21 1oz plants or 4 5oz plants. Personally i would rather do 4 plants spread them out, trim all bottom off and build a nice canopy but thats just doing it for a hobby/intrest. Try both ways see what you prefer brother

    Why not plant one every 3 or 4 weeks, that way you end up with a perpetual harvest? I run 6, 3 at a time in 7 gallon pots.

    Check out my 12/12 sig thread. I went on in that thread to do a 3 cycle, 3 week harvest perpetual. In there is even schedules for everything. Maybe you'll find it useful and can adapt from it.

    I did 9 in 3 gallons under a 1k and they got too big
    Scope my thread there's a link in my thread

    I'd do 16 in 1 gallons but veg quick they usually always double or triple in size after you switch to 12/12 so veg once there like 5 or 6 inches.


    Or do 9 in 2 gallons would be nice but flip right at like 8 inches and you have abunch of 1.5 to 2 footers.

    Hope this helps.
