I have 6 sativa budding in veg and the more I clone off them I’ve noticed the buds getting bigger each time ,they are under 6500k Cfl and about 30k lumens in 3x3 tent just wondering if this is going to hurt anything,oh and they are 33 days in veg some buds close to a 1/2 inch
Welcome to ILGM.
Are these Auto seeds? It sounds like it. How big are the plants? Could you give us some pictures? If you fill out the support ticket below it will give us some information to help you out. We have a lot of experienced growers here.
COPY/PASTE: This “Support Ticket” into your forum post. Answer these simple questions the best you can. If you do not know, or do not use something; Just say so = NA
ILGM Support Ticket:
What is the strain and type(unknown bag seed, strain name, regular seeds, feminized seeds, auto-flower, etc)?
Indoor or Outdoor? If outdoor, planted in ground or in a container?
Size of space (max height and area, length/width)?
Soil or Hydro? Type of Medium used? System type?
pH? Of the soil or medium (root zone/reservoir/run-off) and of the water and/or nutrient mix that is fed to the plant?
Type and strength of nutrients used? NPK? EC/TDS/PPM levels? Of what you feed it as well as what is in the water by itself and in the soil/medium (run-off), or reservoir.
Temperature? Day vs. night temp or highest and lowest temps? Root zone temps?
Humidity %? Day vs. night
Ventilation system? Size? CFM? CO2? AC, Humidifier, De-humidifier?
Number “weeks/days” from into Season, Vegetative Growth or Bloom/flowering?
Add anything else you feel would help us give you a most informed answer. Feel free to elaborate, but try to be brief and to the point. Short and to the point questions and/or facts will help us help you.
Take care and have a good grow. Jerry
Soil FFOF,day temp 80 night temp 65indoor 3x3 all the plants are over 1ft tall I only feed with FFOF big bloom in flower no nutes every other watering I water every 5 days let soil dry out they are now in 1 gal pots started clones in pint pots after they rooted in cloner
What kind of plants are they? Name of the strain ? I agree the sound like autos if they’ve got buds that young.
What light schedule are they on?
Pineapple haze light schedule 18/6 feminised
Pictures? We always like pictures haha
18/6 light schedule
No pics ,sorry they have just started doing this slowly I have cloned these plants for over 2 years but the last 3 times I have cloned its like it’s getting worse I also have feminists white widows and have cloned these with my pineapple and they are not doing it they only show sex or mid preflowers in veg at around 50-60 days cause I veg for 60days then flip for a perpetual grief
The Answer Is:
you have several lighting systems to choose from, including compact fluorescents and high pressure sodium (HPS) lamps. Among HPS lamps you have a choice between a single 100-watt lamp which uses a total of about 120-watts and emits about 8,800 lumens(73 lumens per watt) or a 150-watt lamp, which uses about 180 watts and emits almost double that-15,800 lumens (87 lumens per watt).
A 42-watt compact fluorescent (CFL) emits about 2700 lumens(64 lumens per watt). Four 42 watt CFLs use 168 watts and emit 10,800 lumens. Other size CFLs have a similar efficiency.
However, that is only part of the story. Plants use mostly red and blue light. Yellow and green light is of little use to them, so light that is emitted in these spectrums is wasted energy. Most of the light emitted by HPS lamps is in the yellow spectrum. Only a small amount of the emitted light is in the orange or red spectrums, which plants use efficiently. Warm white fluorescents (2700 Kelvin) emit a greater portion in the red and orange sectors.
Although fluorescents produce only about 75% of the light per watt that the HPS does, the amount of light usable by the plant is equal or probably higher with the fluorescents. You may wish to experiment to see if adding a single cool white CFL to replace one warm white results in shorter, stouter stems and more vigorous growth. The reasoning is that warm whites don’t emit much blue light, which the plants use for photosynthesis and to regulate their growth. The cool white bulb supplies the blue light.
My call for your unit would be to use several (three to five) CFLs with a total input of between 120-160 watts. Although the 150 watt HPS is a bit more efficient that the CFLs in total output, watt for watt the fluorescents provide as much useful light as the HPS lamp. Heat is another consideration. The HPS runs much hotter and emits more heat than the flourescents.
Make sure to use reflective material around the garden so that any light escaping the garden is reflected back to the plants. Any light that doesn’t get to the plant leaves is wasted.
Look at a lumen/watt ration of various CFL’s. The higher the wattage of CFLs, the lower the lumen/watt ratio. This chart was submitted by Jerry Garcia, a grow buddy from another grow site, and edited for typos.
the 200w listed at 9250 lumens for a lumens/watt ratio of 9250/200=46.25
the 150w is listed at 7500 lumens for a l/w ratio of 7500/150=50
the 125w is listed at 6500 lumens for a l/w ratio of 6500/125=52
the 42w are listed for 2700 lumens, l/w ratio of 2700/42=64.28
I have some 26w that give off 1700 lumens for a l/w ratio of 1700/26=65.38
GE lists some 13w that give off 825 lumens for a l/w ratio of 825/13=63.46
So, according to these numbers the most efficient bulbs for growing are the 26w that emit 1700 lumens. If you used 8 26w bulbs (208 watts total) you’d be getting 13,600 lumens…4,350 more lumens than a single 200 watt CFL. AND the eight 26 watt bulbs would cost less than the one 200 watt bulb.
I suppose you need to purchase more sockets and cords and things to support 8 bulbs, but in the long run more lower watt CFLs seem like the way to go.
Hope this helps
@garrigan62 Thank you for taking your time,however this info I already know and I believe I have the proper lighting for veg and flower,I’m very glad you came to this thread can you please reread the thread and my post
