Is 4 plants too many for 70cmx70cm?

@fronti Im wanting to swap it out for an SF4000 soon. But I'm worried because that light is 64cm and my tent is 70cm lol. Bigger light also means more heat. Its at 28 degrees now and when it flowers in a few weeks properly, I'm already concerned the temperature is significantly higher than normal.

Ich hab 9 Stück /SoG oder normal 4 Stück drinnen ! Also alles gut ! Evtl.Bessere lampe

@MrGrowthSpurt I topped them because I have a scrog net. The back left plant is stretching and growing well. But I never get bushy plants like all the other grows I have seen. If you look at my other questions.. I have a previous grow on week 6 with auto ultimate that was better than my current grow, I'm not happy but it is what it is. Better than paying for it lol. My tent is 200cm high, so not a problem. I am just worried I am putting too many plants in this small tent and everything is not growing. Would the tent be better with just one plant?

4 plants in 4 gallon pots in a 3feet by 3 feet tent. Its gonna be a tight squeeze especially once they start flowering, however its should be manageable especially if you perform LST. I have a 4x4x6' tent with 4 10 gallon pots running currently. I wouldn't worry so much as far as the horizontal growth, more so the verticle growth that will happen when they start flowering because in most tents you can only pull the lights up but so high. How tall is your tent?

Also too add because I ran out of characters: I am running in 16L fabric pots. . Bio bizz soil. .Spiderfarmer SF1000. . Plagron 100% organic box . Dutch Passion Auto Ultimate. Is a 70cmx70cm tent only best for 1 plant at a time? I don't mind as at the end of this grow I will swap too only 1 plant if it will make yeild better. It's difficult too water as scrog net gets in the way alongside slotted into place humidifier and dehumidifier. (I have zero space on the tent floor) lol. I am also using 4 pot saucers. Any good advice is appreciated. Thanks.
