How many can I plant?

Dont waste your money , this lamp is no good. For 100 more you can get marshydro tsl 2000. It's around same size. I growing 6 autos, under it. Check my latest grows

I say 4-6 pants depending on how packed you want it! But you’ll need another set of lights to get good buddy! Check in a spider farmer led sf2000 would be perfect for your size! Good luck 🍀👍

Hey @GooseGrower! Fluorescent lamps are OK for growing but they have to be placed relatively near from the top tip of the plants. That means that with that lamp size and 230w of light you can cover effectively around 60x80cm (2,6x3.4feet) or maybe 1x1m. So... around 20-30 plants I should say. You can also use LEC/HPS/LEDs of your final setup but dimmed to match 200w.

A Good general rule of thumb is 1g per watt. It’s a really rough umber as can fluctuate widely. Autos for most people average 40-60g but again can vary widely by strain and grower. So with that said it would be good for roughly 4 autos. These number can also change depending on pot size. Smaller pots=smaller plant=smaller yield= more plants. You may also want to look into a more powerful light because while it will grow Some solid bud, you could increase yields by increasing light wattage. A 5x3 can handle way more than 200. Another general rule is 50w per square foot for hid and 35w per for led as. These are usually looked at as the low end as well. At 15 sq/ft you could easily get away 750w in there. If you have no issue with hps a 600w hps can be picked up for around the same. Pm if you want more help. Hope this helped
