Advice needed please

Hi i have a 1.5x3metre tent with two 600 watt lights and currently growing 8 seed plants each in 30litre pots. Just wondering if these lights are enough for them? Its my 1st grow indoors and have spent alot of money on all the good gear. Please help any advice is appreciated

I advise 9 15 litre pots under 1x 600w hps, thats gives about 1.5x1m coverage ..to 1 meter tall in 3 months with 2 months bud

There are 4 30litre pots under each light and im nearly 4 wks into veg. Have recently topped the 6 biggest ones. Another question how much taller will they get once i go to flower cycle? They are about 10inches tall now

To many variable here, like strain and how you grow, but aiming for a meter high in 3 months is good, at 30 liters is a waste of soil, and further from the light cause of the pot bulk
the idea is to keep the ship vertical, as 600w hps is the best lumen per watt value, the 600w footprint at 90k lumens(400mm/18 inches?)footprint is 1.5x1m to hold 9x 15 liter pots.

ps. if you still want 30 liter pots go get another 600w light, and some extra ventilation

Thanks for your help just assumed the bigger the pot the bigger the plant and no chance of root bound etc. so atm they are 10inches tall nearly 4 weeks into veg. When would you recomend to flick to 12/12?

I like to go 2 months veg and 1 month bud/ flower
