Listen to this guy! +rep. When you do the switch to 2700K you should have the 40-42W (150w replacement equiv.) Bulbs. 2600-2800 lumens generally. And get good coverage, you can produce tight dense buds just like HPS bulbs, by vigelently keeping your lights no more than 2-3" away the whole grow. Keep a nice breeze in that space, and the heat is carried off easily, provided it's exhausted from the grow chamber.Get at least a few of the 26w CFLs (100w equivalent) and make sure they are the "daylight" or 6500k spectrum. Later, when you put them into 12/12 light schedule for flowering you will want to change to the 2700k CFLs that give more of the red spectrum light. Keep the lights close (1-2" away) so they don't make the plant stretch (but be careful not to let the plants touch them for long as they WILL get burned by even a CFL- it happened to one of mine). When you see a taproot start to peek out of that split seed, don't waste any time getting it planted. The longer the taproot sticks out, the easier it will be to accidentally damage it and kill the seed. You break that taproot, you're done! Tiny root means less chance of knocking it off when you plant.
Thats... very low.i have 2 25w cfl's(both say 2700k tho) 1 20w fluorescent and 1 14w fluorescent. not sure wat kind tho.
(they are both very bluish and are aquarium reflectors if that helps)
LOL What?!! No. Every darn seed i've every grown got purple in the stem and /or somewhere on a branch or leaf...I HIGHLY DOUBT, and almost boycott the idea of it being due to stress. Enjoy the colors friend. No worries.usually purple stems indicate low temps, or other forms of stress.
I grew enough plants without any purpling.LOL What?!! No. Every darn seed i've every grown got purple in the stem and /or somewhere on a branch or leaf...I HIGHLY DOUBT, and almost boycott the idea of it being due to stress. Enjoy the colors friend. No worries.
