These plants are in VEG right?

also do you know what strain your plants are. or even if there indica or stavia?

Also what spectrum lights you have (xxxxk)?

More light is needed. Looks like you have stretch if they are in veg.

I use spirals as well. I have 8 in my homemade hood and these are only 100 watt equivs. plus 2 2' floros. (removed some for my clones - for anyone who remembers)

If in veg you could also top emm. count down 3 nodes from the top cola and do a typical clone. Some people dont agree with this but it works if space is needed. I know alot of professional growers take there clones from the top of there plants instead of the lower branches. Like I said I know someone is going to say something about doing this cause I was told not to but others have had good success doing it. I don't know all depends on who you talk to.

How big is the space you are growing in? L x W x H

oldsanclem 30 - 50 watts works. you don't always have to have 50 watts. for bigger better buds yeah but if your starting and don't have the money that isn't entirely needed. You can never have enough light for the babies. There light pigs.
