Athosanswered grow question 7 years ago
5000K or 6500K are very good for veg phase and 2700K or 3000K are ideal for flowering. If you want a mixed spectrum I would use half and half, I know many micro growers that prefer to do it this way, the bluer bulbs (5000K or 6500K) give frostier buds, but yield a little less (and you spend less on bulbs). I myself haven't tried mixing the bulbs yet.
Just don't use cheap no brand bulbs. Phillips carry very good choices I use 6500K 10.5 watts and 3000K 13 watts Philips ones.
As for the amount of wattage, 30 watts per sq ft is an accepted norm in the micro grow community regarding LED bulbs; you can get as low as 20 watt per sq ft and I've seen as much as 50 watts per sq ft. My first diary I was at 26 w/sqft and the last one was at 34 W/sqft and got 3 oz out of it (1.15 gpw).

[2 Pack] LED Grow Light Bulb, SPE 20W E26/E27 Indoor Garden Light Lamp for Hydropononics, Aquatic, Plants, Seedling, Greenhouse, Vegetables, Herbs - 166 Red 34 Blue
The TaoTronics bulb is supposedly full spec and comes recommended on many pages.
But always look at the specifics of the bulb, red light blue light ir etc.
Best of luck with the micro adventure

Can't say i'm a micro grower, but I'd say the principal is the same just on a smaller scale. Light will still be one of your biggest factors on the final outcome, along with air flow and basic feedings. A efficient full spectrum energy saving light would be the 6500K Full Spectrum Energy Saving Bulb 15w ES (=75w) worth looking into at least and you can use a few of them (top light and sides, but one for veg to begin with.

Where to prune fan leaves?Ok y'all, was hoping for a simple, hands off grow with just one topping early on. These babies have turned into dense bushes, and I want to defoliate the undercarriage a bit. Fan leaves are huge from the base to the top, so do I just prune out the lower, older fans?

Should I defoliate or not? Stunted autoBasically at the end of week 3 of flower. Question is, to defoliate or not to defoliate? She’s stunted by about 2 weeks already and I don’t think she’s going to stretch anymore… would she benefit from a light defoliation? A heavy one? Or would it be better to avoid it altogether?

Defoliate? Auto Week2 flower high humidityI’m struggling to keep relative humidity below 65%-70%.
Should I defoliate some lower fan leaves to help with this? Will doing so hurt overall yield? I’m at beginning of week 2 of flower. Any advice on this would be greatly appreciated.

Should I have trimmed the Bush?More than normal I have noticed a large amount of second growth at the base of the plant, im wondering if this is caused by adding new soil during flower? Or if this is normal? Also should I have just cut it off as it grew, seems to be a waste of energy as they won't get light.

Pruning lower growthI read that in maximizing yield you trim off the lowest two set of branches. I am growing my plant horizontally to accumulate more budsites without the use of topping until I have the desired amount of branches. Is it safe to remove the lower two sets of branches?

They appear generally healthy, but is it too early to try lollipoping?
Also, if I do lollipoping, will any other pruning be necessary?

Coteleidoni toltiCiao amici , in cicli scorsi ho sempre levato i coteleidoni ma non vorrei che questa cosa che io faccio danneggi le piante anche se in giro per il web e per le esperienze di altri grower mi dicono che invece levando le due foglioline lo stelo riesce ad irrobustirsi meglio.Pareri?

Scrog Defoliation during flowering - how hard to go?I'm going into 4th week of flower, and I'm fairly sure they're done stretching now, and have filled the screen nicely.
How much should I be defoliating at this point? Should I take just leaves, or also small budsites under the canopy?
