Hi rsj
Looking good ... Glad you got them in the tent now
Where have you got your thermometer ? .... Check the temps at pot hight , Between 75 and 85 at peek heat it optimum temp and thats fine so dont worry to much , Get a reading frm soil hight and let us know whats happnin down there
Question about your drippers ... hard to tell from the pic ... but are they in the soil or above ? ... Might want to concider moving them a bit futher away from the plants and wet the area near the edge of the pots to encourage the roots to go and look for the water rather than giving them water ... They will be happy to not look any futher ... small roots = small plants
Im not sure about the drip thing ... but 15 minz 3 times a day could be excessive ... You might want to concider letting them run dry from time to time ....Others may be able to help with that though
On the whole... Looking good ... and your now well on your way
Are you using Nutes yet ?.. if so what ?... and how much ?
