when to switch fro florecent to hps

hi im just wondering when shall i put my babies under the hps???? they r currently under floro and are about 3 inch tall...is it time??? thanks

I do it after they harden off from the clone process. So about 3 weeks old I suppose.

I suppose it depends on the wattage. Pics would help. Three inches with one node? If it's a high wattage you can start with it a little further away and lower it a little each day til it is at a comfortable distance. If it's a little 175, fuck it fire it up and let em bask in the Caribbean sun.

Height is not necessarily a good indicator...how many weeks old are they? Give em at least 3 weeks preferably 4 to get a good root system going...no roots=no buds, so don't rush it! Then you can put them under some powerful light at a distance, watch them, and move them ever closer...if it's 400w or better, 5 or 6 feet away initially, moving to 18" or so...ya gotta watch the plants and read them correctly to know exactly what they want...DP's are what they SHOULD look like at 3 weeks...he's a master tho! Beer cups, DP? LOL! Only the masters know for sure....Show him the finished buds in beer cups, DP!....Love that pic! LOL!

3 weeks vegging under High Output T5 & then a transplant under 400 watt HID....:rhinoceros:

thanks for your inputs...i germinated them a week ago on in tissue n that,,then put them in their pots the day after with the roots bein inbetween 2-4 cms..a few have 2 nodes a few only 1..my last grow went fine got what i wanted but just abit curious this time as im doin more :) ,ive got 2 600 watt hps when there ready tho..so you say leave them a week longer????? thanks
